What is the minimum 3dB change threshold for acoustic perception?
From a professional specification perspective:
Most people notice a 3dB change in sound level, which is the smallest difference typically perceived by the human ear. This means acoustic improvements of less than 3dB are unlikely to be noticed by occupants. FSA Network floor sanders ensure acoustic underlay selections achieve meaningful noise reductions well above this perception threshold.
