Reverberation Control

Reverberation Control

A major cause of discomfort in buildings is excessive reverberant noise caused by hard reflective surfaces such as painted plasterboard, concrete, ceramic, wood flooring, plastics and glass.

Excessive reverberation raises back ground noise levels and affects speech intelligibility, privacy, the old and those with hearing difficulties.

Reverberation is easily controlled by use of good quality sound absorbing finishes. Absorbers are classified according to ISO 116 54 and fall into 5 class groups Rated A to E.

Class A absorbers are highest and provide more absorption per sq.m than other finishes which often means less is required. Most of the Asona composite soft fibre panels are Class A. Similar to ASTM C423 NRC 0.85 to 1.00 range
