Summary
•
Acoustics may be invisible, but they are a significant factor in our well-being and health.
•
Whether acoustics are good or poor is determined by reverberation time.
•
To regulate reverberation time, sound-absorbing elements must be added to the space.
•
These elements should be positioned to ensure the acoustics support the room’s function.
•
Achieving the right balance requires evaluating how much sound-absorbing material is needed and
selecting the appropriate acoustic class.
•
The alpha value is crucial in assessing a material’s sound absorption properties and determining its
acoustic classification.
•
There are three types of sound absorbers: porous absorbers, membrane absorbers, and resonance
absorbers.
•
Thanks to membrane and resonance absorption, hard surfaces like metal can be used in acoustic
solutions - despite what intuition might suggest.
•
Metal offers several advantages as an acoustic solution: acoustics, design, and sustainability.
