Extract

The acoustics of a university council chamber room in a retrofitted and restored woolstore
building presented a problem of speech intelligibility. A decision was made by the university
to engage the Built Environment Research Group (BERG) in an acoustical analysis of the
space before the installation of a costly sound amplification system. This analysis included
the results obtained using a B&K-Investigator (acoustic meter) for reverberation and
background noise level measurements. These measurements were incorporated into the
virtual model, BOSE-Modeller, acoustic software package. After adjusting and tuning the
virtual model to match the measured results, an analysis of speech intelligibility levels and
acoustic alterations to the space were undertaken. This paper presents the process between
acoustic measurement of a space and its analysis via a computer program. It reports a
method of how acoustic problems can be solved and studied before real-world
implementation.
