Reverberant noise bouncing inside large enclosed spaces
is reduced by adding acoustic absorptive panels on ceiling, walls and around noise sources.
An added benefit is to improve sound communication and safety
in the workplace or play spaces, namely (1) speech intelligibility between people, (2) Detectability of PA system
and alarm bell, (3) worker's ability to locate threatening noise sources such as an incoming fork lift truck. This is
even more important for hearing impaired people.
Silentec uses room acoustic prediction software, developped
in cooperation with with the National Research Council of Canada, to select the type of panel, dimensions and spacing.
Furthermore, panel design account for such things as fire
insurance, dust, maintainability, ease of installation, mechanical protection and overall cost per decibel of noise reduction.
It is often a low cost noise reduction method.
