In the last decade, the advent of MEMS (MicroElectroMechanical Systems) technology applied to microphones and accelerometers has led to the development of small and inexpensive digital sensors with good performance. These sensors, born in the gaming and IT fields, are composed of a sensitive element and analog-digital converters integrated in volumes on a millimeter scale. The main advantages of digital MEMS sensors are extremely low costs and easier digital signal processing. For this reason they begin to find new and particular applications within extended networks of low-cost wireless sensors that allow to collect large amounts of data in real time for environmental or industrial monitoring, where, on a large scale, it is not always necessary. have high precision sensors, but at the same time metrological traceability is necessary, in order to guarantee the effective accuracy of the measurement. Furthermore, sensor networks require sophisticated data management, in terms of connection, transfer and analysis, and an adequate IT hardware and software infrastructure. However, for these extensive sensor networks it is not always possible to implement standard calibration procedures, which, in addition to technical differences, are not suitable in terms of cost when compared to the low cost of the sensors themselves. Consequently, as also reported by the BIPM strategic vision document in the context of emerging metrological requirements for the future, it is necessary that these technologies «are supported by a new metrology to support reliable and safe operation (including digital sensors) and to guarantee traceability chains and quality management requirements “.
In this webinar, the first of the second cycle of “Waiting for Matera”, we will talk about MEMS and extended monitoring networks together with Luca Nencini, Jacopo Fogola and Andrea Prato, respectively experts in production and adaptation, environmental applications and sensor calibration and traceability issues.
We will try to understand what they are and why they are cheap, what are the prospects and limits of general use for environmental measures, how they are used in networks for noise and vibration control and how to deal with the problems related to the management of large amounts of data and the need for good connection and large-scale reliability.

Auralization and acoustic spatialization are topics that have been widely developed, especially during the last few decades, in conjunction with the advancement of technologies. Among other things, the virtual 3D reconstruction – both sound and visual – of architectural and natural environments has represented in the last year the way to escape the restrictions of domestic spaces, considered very limited. Therefore, the evolution of microphones and spherical sound sources, equipped with mini capsules respectively for the recovery and restitution of sound, are the expedients through which the virtual reconstruction is made possible both in special listening rooms and through the ” use of cheap devices (such as smartphones and normal headphones).
During the seminar the operating methodologies and applications that took place both in closed or confined places such as the historical Italian nineteenth-century theaters will be exposed through the data collection of the SIPARIO project, and outdoors by exploiting the natural architectures of Paleolithic caves and inlets of which the project ARTSOUNDSCAPE is one of the leaders.
Through a “virtual” reconstruction, the acoustic evolution of the Roman theater of Benevento will be presented: from the original conformation in the imperial era, the abandonment following historical events and natural events, the decadence with the construction of houses in the cavea making it lose the memory until the rediscovery at the end of the 19th century and the return of the theater to the city in the mid-20th century.
Some results will then be shared which will be later discussed both from an acoustic and architectural point of view.

Thanks to the reduced CO2 emissions during the entire life cycle, wind energy is currently considered one of the most efficient energy solutions with the lowest environmental impact where the systems are installed in sites with adequate wind. However, the acoustic impact, together with the visual one, represents a significant obstacle for the construction of new wind farms, usually installed in places where the quiet and the landscape are the main attractions. Unlike the most common sources of road and railway noise, the noise produced by wind power plants has particular emissive characteristics and strictly dependent on natural phenomena. This has led to the development of specific measurement procedures for compliance with the emission levels, which also provide for a correct determination of the relationships between the wind profiles and the propagation of noise in the prevailing atmospheric conditions. The presence of low-frequency spectral components, amplitude modulation and a multiplicity of moderation factors, both environmental and subjective, are among the main aspects able to explain how, at the same level, wind noise is more disturbing than that produced by other environmental sound sources.

Performance-based design (PBD) approaches are arousing growing interest in architectural design for two reasons: on the one hand, they give the opportunity to explore the performance of a building from the early stages of the design process; on the other hand, the limits of technology are gradually smaller, thanks to the availability of digital tools that are easier to use and more functional. However, the adoption of PBD in acoustic design is still infrequent, despite the fact that these tools allow you to combine different perspectives (e.g. acoustic and visual) at the same time by exploring geometric and material solutions that can adapt to optimal parameter values and perceptual criteria.
In this seminar some successful professional, didactic and research experiences will be presented. Despite having different objectives, these three perspectives agree in two key aspects that, at present, prevent the use of PBD tools on a large scale: it is necessary to improve the integration and interoperability between modeling and simulation tools and, together, improve the acoustic knowledge and programming skills of architectural professionals.

Many significant evidence of non-auditory effects of noise exposure on workers’ health has emerged in recent years. Among the surveys present in the literature, in the various occupational scenarios, the environments intended for teaching are particularly critical and are of particular interest for the medical-scientific and technical aspects that could lead to a revision of the legislation. At the moment, the Consolidated Law on safety at work does not expressly include the assessment of extra-auditory risk and even in the accident and forensic field there is little evidence of non-auditory damage, whether of a physiological, neuro-behavioral or perceptual-cognitive nature.
School activities often take place in classrooms with inadequate acoustic properties, where the background noise is high and has unfavorable spectral characteristics. Exposure to noise seems to have a significant impact on the behavior of kindergarten and primary school pupils and on the reactions of teachers to lead children to silence or to moderate the typical excesses of developmental age.
The BRiC INAIL 2019-ID 14 project sees five Italian universities engaged in ambitious research work on how inadequate acoustic contexts can lead to impairment of cognitive skills, particularly critical for the development of children, as well as an increase in the effort associated with speech. and listening, with the onset of fatigue and pathological or behavioral consequences in students and teachers of schools of all levels.
In this webinar of Aspettando Matera, the first results of the research will be presented, including the results of the research and cataloging of extra-auditory damage, through a reasoned review of literature and jurisprudence. The interventions will concern the cataloging of sources and scenarios capable of generating extra-auditory damage, first of all the vocal effort, and the possible implications deriving from the incomplete and univocal consideration of the problem at the legislative, regulatory and juridical level.
We will also discuss the medical aspects, the effects on heart function deriving from the increase in heart rate and blood pressure; how exposure to noise increases respiratory rate, disturbs the balance organ and even the digestive system. And above all the effects on the voice, one of the best known effects in the medical field, but ignored by the layman.

With the contribution of
AIA 2021 Gold Supporter.Many significant evidence of non-auditory effects of noise exposure on workers’ health has emerged in recent years. Among the surveys present in the literature, in the various occupational scenarios, the environments intended for teaching are particularly critical and are of particular interest for the medical-scientific and technical aspects that could lead to a revision of the legislation. At the moment, the Consolidated Law on safety at work does not expressly include the assessment of extra-auditory risk and even in the accident and forensic field there is little evidence of non-auditory damage, whether of a physiological, neuro-behavioral or perceptual-cognitive nature.
School activities often take place in classrooms with inadequate acoustic properties, where the background noise is high and has unfavorable spectral characteristics. Exposure to noise seems to have a significant impact on the behavior of kindergarten and primary school pupils and on the reactions of teachers to lead children to silence or to moderate the typical excesses of developmental age.
The BRiC INAIL 2019-ID 14 project sees five Italian universities engaged in ambitious research work on how inadequate acoustic contexts can lead to impairment of cognitive skills, particularly critical for the development of children, as well as an increase in the effort associated with speech. and listening, with the onset of fatigue and pathological or behavioral consequences in students and teachers of schools of all levels.
In this webinar of Aspettando Matera, the first results of the research will be presented, including the results of the research and cataloging of extra-auditory damage, through a reasoned review of literature and jurisprudence. The interventions will concern the cataloging of sources and scenarios capable of generating extra-auditory damage, first of all the vocal effort, and the possible implications deriving from the incomplete and univocal consideration of the problem at the legislative, regulatory and juridical level.
We will also discuss the medical aspects, the effects on heart function deriving from the increase in heart rate and blood pressure; how exposure to noise increases respiratory rate, disturbs the balance organ and even the digestive system. And above all the effects on the voice, one of the best known effects in the medical field, but ignored by the layman.Relatori

The COVID-19 pandemic spread to Europe after a few months of first appearing in China and Far Eastern countries and before spreading across the planet. The virus has had and is having terrible consequences on people’s health, governments and health authorities of various countries have often reacted by introducing restrictive measures to contain the phenomenon, including the closure of buildings and public areas until the complete lockdown. In this critical scenario, however, some positive effects were also observed. From an environmental point of view, in fact, during the lockdown there was a reduction in road traffic, as well as a reduction in navigation and air transport activities, which led to a significant benefit for air quality and emissions of noise in the cities.
During the seminar we will discuss the consequences that the pandemic has had in terms of objective reduction of noise levels, but also in relation to the perception of the sound landscape by citizens.
A summary of the results of the noise monitoring carried out, using smart sensors, in an urban area of the city of Monza, before, during and immediately after the lockdown, will be shown, using the data collected by the LIFE MONZA project. Some results of two international projects will then be shared, the first of which aimed at the documentation and subsequent analysis of the changes in the sound landscape, conducted in the different phases of the lockdown in a town in the Basque Country, in northern Spain; The second, The Sound Outside, which tells of the lockdown in the world during the first phase of the pandemic and which saw the participation of more than 100 sound professionals from various countries. The data objects presented will then be discussed from a philosophical point of view, in order to understand how our auditory perception has been strongly influenced by listening to the sounds of cities “in silence”.

The environmental quality of school environments is a multidisciplinary theme that covers thermo-hygrometric, acoustic, visual and air quality aspects. These aspects are very strongly correlated with each other, particularly in the behavioral reaction of students. An example: despite being hot, would the students open the window if it looked out onto a noisy street?
The study of these issues has assumed great importance following the health emergency, when the well-being of students has become a priority for institutions and families.
The webinar will see the intervention of two speakers: Federica Morandi, collaborator of Prof. Andrea Gasparella (unibz) and a school director. The results of the #vogliamoinvertirelarotta project will be presented, a research carried out at the beginning of 2020 on comfort in classrooms, through the analysis of thermal, acoustic, visual comfort and air quality. Students’ evaluations and their behavior in reaction to a non-optimal environmental stimulus will be presented. And it will be an opportunity to read these data in light of the recent return to school.

Correctly hearing, understanding and memorizing the teacher’s explanations are essential aspects in the learning processes that take place within the classroom, and which require the establishment of correct verbal communication between teachers and students. Classroom acoustics are therefore of great importance in facilitating or hindering students in their learning processes, and it is essential to carefully design school environments with the primary objective of reducing background noise and controlling the sound tail.
Students who learn in classrooms with favorable acoustic conditions will be able to hear better what the teacher is explaining, keep attention focused while carrying out a task and, over the years, develop better phonological skills, math and reading-writing skills . Conversely, poor acoustics not only compromise students ‘performance in academic tasks but also affect the amount of cognitive resources required of students to perform those tasks, impacting the speed with which new information is received and students’ motivation to stay focused. on the task. These effects are more pronounced for students of lower grades (primary school, lower secondary school), i.e. for those age groups in which key skills are developed from a cognitive, linguistic and academic point of view.

Anthropogenic noise, ie the noise generated by people, has so far been kept on the border of acoustic regulations due to its nature of “non-reproducibility”. Consequently, the technical-acoustic community faces it in a partial way, despite being the main sound source and cause of disturbance in many contexts, such as nightlife environments, restaurants, open-plan offices and school environments.
While international research has been studying for some time the effects that anthropogenic noise causes on comfort, well-being and productivity, an open problem is that of its measurement. Typically the anthropogenic contribution is added to other sources of noise: in nightlife contexts to traffic noise, in offices to noise from systems, in classrooms to the teacher’s speech. Recent applications of simple data-analysis algorithms make it possible to isolate the anthropic contribution and quantify the contribution of sound emission, in compliance with current acoustic regulations.
Among the solutions to mitigate this noise source, acoustic treatments are not sufficient, therefore it is desirable to promote the use of new strategies capable of encouraging virtuous behavior in people. In this sense, noise awareness campaigns have been organized and monitoring devices have been introduced, such as an “acoustic traffic light” which continuously detects the level of anthropogenic noise and warns, through light feedback, when it becomes disturbing.

Antonio Pappalardo, Mastro Pizzaiolo, La Cascina dei Sapori, Rezzato (Brescia), I couldn’t say when my passion for cooking began, because I am convinced it was born with me, and it has always accompanied me. Even as a child I loved helping my parents while they worked in their restaurant, and it wasn’t just a game, there was more. Something was probably already starting to make me understand what my path would be, and I always tried to follow it. It was precisely following it that I chose the hotel school for my high school education, graduating in 2008. And always following the same path I started my first work experiences, from which I tried to make the most to give even more definition to my passion. I wanted my training in the kitchen to be complete, and at the same time help me to take a specific direction. I worked in the kitchen, pastry shop and pizzeria, and that’s how I understood that the right answer for me was pizza. Because with pizza I didn’t really have to choose, I knew I was giving my creativity the possibility of having no limits. From the appetizer to the dessert, any dish I wanted to make I could combine with a well-leavened disc of dough, transforming a dish that was already unique into something even more special.
The new UNI 11532-2: 2020 standard for the acoustic quality of school environments aims to bring order in a field of standards that has been stratified over time and is not free from ambiguity. Made mandatory by the CAM of 2017, the standard is part of a broad context of European regulations on the subject (such as the English BB93, the German DIN 18041) introducing two substantial innovations. The first concerns the indication of a compliance interval of the reverberation time, according to the intended use and the volume of the environment. For intended uses that require the static presence of a person, this interval takes into account the acoustic absorption of the occupants. The second novelty concerns the forecast evaluation of the C50 / STI intelligibility criteria. The use of these descriptors, already anticipated in the CAM 2017, is detailed here and related to the specific context of the school environments (e.g. the role of background noise, the vocal effort of teachers …). The introduction of new design logics has consequences on the materials and on the different design criteria to be implemented according to the grade of the structure. Some case studies will be discussed and analyzed from several points of view: respect for design criteria, perception analysis, choice of materials.

Since 2015 he has been included, representing AIA, the Italian Acoustics Association, in UNI Working Groups (National Technical Standardization Body) operating in the field of acoustics. In 2015 he was called to be part of the ISPRA / Ministry of the Environment working group aimed at adapting the national acoustic legislation to the European provisions of the sector, directives 2002/49 / EC, 2000/14 / EC and 2006/123 / CE and Regulation n. 765/2008 / EC. He is author and co-author of scientific works on acoustics.
Antonio Pappalardo, Mastro Pizzaiolo, La Cascina dei Sapori, Rezzato (Brescia), I couldn’t say when my passion for cooking began, because I am convinced it was born with me, and it has always accompanied me. Even as a child I loved helping my parents while they worked in their restaurant, and it wasn’t just a game, there was more. Something was probably already starting to make me understand what my path would be, and I always tried to follow it. It was precisely following it that I chose the hotel school for my high school education, graduating in 2008. And always following the same path I started my first work experiences, from which I tried to make the most to give even more definition to my passion. I wanted my training in the kitchen to be complete, and at the same time help me to take a specific direction. I worked in the kitchen, pastry shop and pizzeria, and that’s how I understood that the right answer for me was pizza. Because with pizza I didn’t really have to choose, I knew I was giving my creativity the possibility of having no limits. From the appetizer to the dessert, any dish I wanted to make I could combine with a well-leavened disc of dough, transforming a dish that was already unique into something even more special.

The new UNI 11532-2: 2020 standard for the acoustic quality of school environments aims to bring order in a field of standards that has been stratified over time and is not free from ambiguity. Made mandatory by the CAM of 2017, the standard is part of a broad context of European regulations on the subject (such as the English BB93, the German DIN 18041) introducing two substantial innovations. The first concerns the indication of a compliance interval of the reverberation time, according to the intended use and the volume of the environment. For intended uses that require the static presence of a person, this interval takes into account the acoustic absorption of the occupants. The second novelty concerns the forecast evaluation of the C50 / STI intelligibility criteria. The use of these descriptors, already anticipated in the CAM 2017, is detailed here and related to the specific context of the school environments (e.g. the role of background noise, the vocal effort of teachers …). The introduction of new design logics has consequences on the materials and on the different design criteria to be implemented according to the grade of the structure. Some case studies will be discussed and analyzed from several points of view: respect for design criteria, perception analysis, choice of materials.
