Eterno Ivica and acoustic comfort for sports facilities
To optimize the acoustic performance of the Motta di Livenza (TV) Pattinodromo, 395 sound-absorbing panels supplied by Eterno Ivica were installed, designed to meet the needs of a 15000 cubic-meters space.
Sports facilities pose a challenge for acoustics and for all those who study sound propagation in space, because these spaces are often characterized by large volumes, reflective materials, and hollow surfaces that amplify reverberation and noise. In fact, these spaces are neglected at the acoustic design stage; therefore, they require customized solutions to ensure proper sound propagation and a careful choice of sound-absorbing materials to be adopted to counteract these annoying phenomena (noise and reverberation).
Reverberation and noise in gyms are caused by the reflections of sound waves on surfaces, (floor, walls and ceilings) which, bouncing repeatedly, persist for several seconds in the rooms and, adding up to the original sounds, cause an increase in sound pressure, creating confusion.
The intervention in the Pattinodromo: a custom-made redevelopment
The Pattinodromo, with a volume of over 14000 cubic meters, has been the subject of numerous warnings from users about acoustic bother. In response, the Municipality of Motta di Livenza engaged a Technical Acoustics Expert (TCA) to study a solution and minimize the problems.
After conducting a phonometric survey and analyzing the results (as noted in the graphic below), the designer in charge of the renovation chose to rely on Eterno Ivica to select the most suitable materials to reduce reverberation time.
The identified solution included the installation of sound-absorbing panels on both walls and ceilings, thus solving the problem of sound reflections, the main cause of the reverberation phenomenon.
Selected soundproofing panels meet basic requirements such as impact resistance, sufficient rigidity, fire safety and mechanical stability, as well as ensuring excellent aesthetic performance.
Eterno Ivica’s solutions chosen to solve acoustic reflections in the sports facility
The acoustic upgrading project of the spaces required Eterno Ivica to supply: 248 Phonolook Solution Rectangle soundproofing panels (900 mm x 2400 mm, 5 cm thick) installed on the ceiling, fixed with steel cables and snap hooks, and 147 Phonolook Solution Rectangle panels (900 mm x 1200 mm, 10 cm thick) applied on the wall, with a special anchor system.
When the installation of the panels inside the building is completed, Eterno Ivica’s team of technicians performed additional phonometric measurements, which showed a significant reduction in reverberation time, as shown in the graph below.
The final result fully satisfied both the client and the visitors of the Pattinodromo, combining excellent acoustic performance with harmonious and functional design. Eterno Ivica stands out, once again, as a partner of choice in the acoustic upgrading of large spaces.
