Acoustic Measurement Systems
Even AuSIM's audio simulation is only as good as the model parameters within the simulation. For AuSIM, deriving optimal model parameters begins with studying the acoustic world around us. The AuSIM3Dtm display systems synthesize a virtual aural environment from parameters based on the physical world. But the same techniques can be applied to reverse the process and extract parameters from the physical world to use for later synthesis.

A Global Standard for Acoustic Absorption Measurements
Alpha Cabin
The Alpha Cabin has been especially designed for the measurement of acoustic absorption properties of materials and components used for the noise insulation of vehicles. The Alpha Cabin is significantly smaller than normal reverberation rooms and therefore ideally suited to use within limited space capacities. The acoustic absorption of the Alpha Cabin itself is also very low: Thanks to the high level of sound insulation, background noise in the frequency range of interest is kept to a minimum.

Acoustic Emission Sensors
Acoustic wave (acoustic emission) sensors are the ceramic piezoelectric transducers converting the mechanical elastic acoustic waves generated in the material (e.g. elastic waves occur when a material cracks, wears, deforms, or corrodes) to electrical signals. The electrical signals are then amplified and filtered by a preamplifier and then transmitted to a special acoustic emission acquisition instrument for further data processing and analysis.
