Our capabilities allow us to analyse a large variety of acoustic problems in the
industrial, automotive and mining industries. This is achieved by means of a range of
instrumentation – from portable Sound Level Meters, to 3-dimensional sound
intensity probes. This instrumentation is complemented by a range of proprietary- and
internally developed software, including acoustic finite element analysis as well as a
comprehensive software library for assessments according to ISO/SANS standards.
