Offices and other workplaces can harbour reverberation noise that adversely affects many individuals over many commercial and industrial sectors but Hush Acoustics has created the Hush Absorber range to counteract excessive levels.

The issue arises when a sound source stops within an enclosed space, e.g. people speaking within a room with sound waves that continue to reflect off the room’s surfaces until they eventually stop.

This reflected sound is known as reverberation and is affected by various factors including the size of the room, surface finishes and the décor/styling. Reverberation Time (RT) is the amount of time it takes for the reverberant sound to die down by 60dB fin when the original sound source stops. Highly reflective surfaces, e.g. hard flooring and blinds are replacing carpets and curtains, therefore amplifying the ambient sound levels of the room.

The acoustic absorber panels from Hush Acoustics have a Class A absorption rating and comply with UK Building Regulations Approved Document E (England & Wales), Section 5 of the Scottish Building Standards (Scotland) and Approved Part G (NI), in addition to BB93 Standards for Acoustics in Schools.

Available in a range of colours, sizes and finishes, the absorber panels can be fitted in either portrait or landscape orientation and to both walls or ceilings. 

School case study

In one example of a primary school, high reverberation levels, particular in a multi-use hall and dining area meant morning assemblies, were often a struggle as noise levels meant speech clarity was poor and as a result, pupils’ concentration levels and learning abilities were adversely affected.

Hush Absorber Panels helped bring the school hall reverberation levels in line with BB93 guidelines. Installation of the panels was completed within two days and as a result there was a ‘noticeable difference’ in the levels of reverberation noise with teachers finding it easier to present assemblies and a noticeable increase in the pupils concentration levels . 

Picture: Noise reverberation levels can have a damaging impact on the work environment but can be dealt with by products like acoustic absorber panels from Hush Acoustics
