Webinar “Beyond sound absorption – Towards zero impact acoustics”

Moderator: Arianna Astolfi (Politecnico di Torino)

The construction industry generates the largest waste streams in Europe, and in total around 38% of global greenhouse gas emissions. Deciding which sound-absorbing product to choose for a building is not trivial. Acoustic performance, design needs and budgets are usually evaluated. But today we know that every product present in a building also has an impact on the internal and external environment. Therefore, it has become imperative to look beyond acoustics and also take environmental impact into consideration. With reference to sustainable building certifications, our products can contribute to obtaining various credits. Low consumption buildings, with a low environmental impact, built with eco-compatible materials and with a high content of recycled material. Designed in this way, buildings become healthy environments for those who live there. Indoor air quality refers to the air you breathe in confined spaces. Room ventilation therefore plays an important role in ensuring good indoor air quality. This is why Ecophon promotes diffused ventilation false ceilings, which combine acoustics with air quality. Still relating to air quality, it is also essential that the materials comply with the criteria of low VOC (volatile organic components) emission. Regarding acoustic and sound comfort: noise is one of the main sources of stress and discomfort, especially in shared spaces such as offices, classrooms and hospitals. Numerous studies have shown that excessive noise can increase stress levels, reduce productivity and even lead to health problems such as hearing loss and cardiovascular disease. Some certifications evaluate various elements of the sound environment, including sound level measurements, speech privacy, noise reduction, and soundscapes. All these factors contribute to creating an environment conducive to well-being in different ways.

Speakers

Cristina Carrus for Ecophon: Ecophon is distributed in Italy by Saint-Gobain Italia S.p.A. and, develops and produces acoustic products and systems such as: false ceilings, sound-absorbing wall systems, islands, grilles and accessories for the installation of complete systems.

The headquarters is located in Hyllinge, just outside Helsingborg, Sweden. Ecophon is part of the Saint-Gobain group. Ecophon invests in research and development to create systems that keep pace with market demands and to create sustainable solutions. The brand has been collaborating with universities and research bodies for years to investigate the effect of sound on people and measure the negative effects caused by non-optimal acoustic design. For this purpose, a group of experts around the world specializes in the dissemination of acoustics and psychoacoustics and in creating healthy sound environments. We are leading the transformation towards sustainability in our sector, through the innovation of products, processes and projects that bring us closer to a circular business model. Involving all our partners and stakeholders in the journey towards zero-impact acoustics.

Webinar “Automatic Monitoring Services (AMS): Useful platform for the creation of a synchronized system for monitoring noise, vibrations, weather and dust produced by construction activities”

Moderator: Patrizio Fausti (University of Ferrara)

Construction activities involving urbanized areas can cause a series of disturbances and/or damages which can affect numerous sensitive receptors present near the construction site area. Such disturbances and/or damage may be caused by:

dynamic stresses in the ground (vibrations) due to the use of machinery and/or explosives;
use of noisy machinery;
dust produced by activities.
Thanks to the SvanNET AMS platform and the SV 307A and SV803 monitoring stations, it is possible to create a synchronized system that allows real-time verification of environmental impacts. The user will thus have useful data to plan, where necessary, mitigation interventions to control impacts. The purpose of the presentation is:

provide details about the functionality of the system;
illustrate the architecture of the integrated system;
describe the various elements that contribute to the creation of the system.

Webinar “Soundscape: new possible criteria for evaluating sound quality”

Moderator: Francesco Asdrubali (University for Foreigners of Perugia)

Sound quality metrics are often used to analyze complex sound scenarios such as Soundscape, to evaluate the impact on the health and well-being of people in a given environment. To create a metric based on the results of listening experiments, Psychoacoustic indicators are usually used, calculated as maximum, average or percentile in a linear combination. In many cases, the importance for the perception of individual events in terms of duration, amplitude and attendance through new evaluation criteria.

Webinar “Solutions for the localization of acoustic sources via beamforming”

Moderator: Luca Barbaresi (University of Bologna)

The beamforming technique is increasingly required for the identification of noise sources. The immediate visual response and the ability to follow the temporal evolution of the phenomenon have made this application indispensable. MEMS microphones have brought the cost of this technique within everyone’s reach, increasing its possible applications: acoustic insulation, gas leaks, electrical discharges, construction defects, fault detection are just a small example of the potential of these new products for the technician acoustic. Starting from the operating principles, some technical solutions will be presented through experiences in building acoustics, automotive and industrial systems.

Webinar “Parametric acoustic design through computational design”

Moderator: Paola Pulella (Vie en.ro.se.Engineering)

Computational design and digital manufacturing offer designers and architects the ability to represent and simulate acoustic performance with remarkable precision and to customize and control material and geometric properties. WOOD—SKIN creates an opportunity for dialogue in the design phase to treat sound as a guide for the design itself, offering the designer a simple way to differentiate the material and geometric treatment of existing rooms towards acoustic improvement.

Speakers

Giulio Masotti for WOOD-SKIN: As architects and designers we know how difficult it is to design and build complex shapes. This is why we created W-S, a product and a team to create impossible surfaces. 3D ACOUSTIC SURFACES: The patented WOOD-SKIN® technology is the heart of our projects. Our digital manufacturing process allows us to create world-class 3D acoustic surfaces quickly and easily. We have developed a technology made of software and selected materials that help designers to easily recreate organic shapes, giving the project a unique structure and aesthetic. The three-dimensionality of the WOOD-SKIN surfaces, the perforation possibilities and the optimization of the software contribute to creating a high-performance acoustic panel. In the rear part of the panel, between the WOOD-SKIN membrane and the ceiling/wall on which it is applied, an air gap is created. In this cavity, essential for acoustic performance, it is possible to insert a sound-absorbing material. On the front of the panel, the surface can be perforated based on aesthetic and technical needs, while the 3D surface guarantees unparalleled diffusion performance.

Paola Pulella graduated in 2020 in Architectural Engineering at the University of Pisa with a thesis developed at the Department of Audio Information Processing (Technical University of Munich). She qualified as an architect and engineer in the same year and has been registered in the National List of Competent Acoustic Technicians since 2022. She works as an acoustic consultant collaborating with Vie en.ro.se. Engineering, an Italian company specializing in environmental, construction and industrial acoustics. In the professional field, he has taken part in the acoustic design of interior spaces for the improvement of the acoustic quality of environments dedicated to speech, in the definition of acoustic solutions for the reduction of sound emissions generated by industrial and civil systems, in the acoustic impact analysis of infrastructures and the acoustic characterization of mechanical components. You have collaborated in research activities with various Italian universities.
