Abstract
The purpose of this thesis was to develop a portable, standalone
building acoustics measuring instrument that would
replace the existing equipment used. The existing equipment
consisted of a number of instruments making it bulky and
time-consuming to operate. The proposed Building Acoustics
Analyser (BAA) was to incorporate all the existing equipment
into a single computer-controlled instrument. It was
anticipated that the completed instrument would increase the
speed of measurements and improve the accuracy of the
results.
A sound generating section and a sound measuring section of
modular design were combined in the BAA. These sections
consisted of analog cicuitry that performed all the analog
processing and was controlled by digital circuitry. The
analog signals were converted to digital format and
interfaced to a computer and software package. This enabled
measurements to be performed automatically and the data to
be stored in memory for further processing.
Tests performed on and with the BAA showed that the
instrument conformed to all the applicable standards and
specifications. The BAA reduced measurement time by about 75
percent and the results proved to be more accurate than the
traditional methods. The BAA, because of its modular design,
also offers the ability of being modified to perform other
types of sound analysis.
