Accordial

Surveys

Using recognised standards for the measurement of reverberation in rooms, Accordial can provide on-site surveys to measure acoustic room environments. Such testing in existing buildings allows the scope of reverberation issues to be monitored and enables recommendations to be made into how acoustic treatment can be best applied to optimise room performance.

This capability is supported by a wider range of acoustic services including sound insulation testing of movable walls to BS EN ISO 140-4.

BS EN ISO 8233:1999 states that the optimum reverberation time for any given space depends on the intended use of the room and the volume of the space. Building Bulletin 93 (BB93) aims to provide a regulatory framework for the acoustic design of schools in support of the building regulations.
