GREAT DESIGN IS A LOT MORE THAN GREAT AESTHETIC
It takes into account other critical detail, such as sound, in theaters, public spaces, museums,churches and schools where we live, work and play. It can enhance or inhibit human interactions, learning and healing. Understanding sound and how it's most typically measured is critical.
Sound insulation is required in order to eliminate the sound path from a source to a receiver such as between apartments in a building, or to reduce unwanted external noise inside the building.
Sound absorption occurs when some or all the incident sound energy is either converted into heat or passes through the absorber.
Although insulation and absorption are diﬀerent concepts, there are many instances where the use of sound absorbers will improve insulation.
However, absorption should not be the primary means of achieving good sound insulation.
Understanding of Acoustical Performance
Noise reduction Coeﬃcient (NRC)
Measures the amount of noise a panel can absorb.
Higher the NRC, the less sound is reflected
Critical in open plan oﬃces
Ceiling Attenuation Classification (CAC)
Measures the amount of sound passing through a panel and the plenum into an adjacent space
CAC performance is most critical in “closed oﬃce” applications where privacy is a major consideration.
Sound Transmission Class (STC)
Weighted Sound Reduction Index (Rw)
TYPICAL SOUND PRESSURE LEVELS
GOOD CONSTRUCTION PRACTICES:
a) It is important to address and seal all possible paths for ‘flanking noise’.
b) Noise not only passes directly through a shared wall but finds ‘flanking paths’ through poor joints between the wall and floor, poorly sealed penetrations, ceiling spaces, floor spaces, ductwork and even other walls.
c) Adequately seal all floor/wall junctions along perimeter with flexible fire/acoustic sealant.
d) Skirting is not to be used alone to seal gaps.
e) Cornice installed correctly can also provide an acoustic barrier to minimize flanking; an airtight seal must be achieved and maintained.
