Specifying a dB rating

When specifying an acoustic partition determining the dB rating is a key consideration for the soundproofing the product needs to achieve.

 

Understanding Sound
The below gives a guide to the acoustic levels and their suitability for your needs so you can be well informed when choosing your acoustic partition.


Sound levels:

20dB Rw – Normal speech readily audible
25dB Rw – Loud speech clearly audible
30dB Rw – Loud speech audible under normal conditions
35dB Rw – Loud speech audible but difficult to distinguish
40dB Rw – Loud speech faintly audible but cannot be distinguished
45dB Rw – Shouting audible but cannot be distinguished
50dB Rw – Shouting barely audible
