Sound and Vibration Test Systems

HEAD acoustics is well known in the noise and vibration community for their pioneering efforts in artificial head (Aachen Head) technology and psychoacoustic workstations that are the standard for evaluation of product Sound Quality. The artificial heads or HEAD Measurement Systems allow for binaural recordings that provide exceptional realism or "virtual reality" when played back. By listening to binaural recordings while analyzing data on the ArtemiS analysis system, the operator can quickly identify and troubleshoot noise problems and select the best metrics for noise evaluation. HEAD acoustics has expanded from their base of "binaural" products to offer multichannel analyzers to handle virtually any noise and vibration test requirement, including FFT and 1/3 Octave analyzers, order analysis, Zwicker Loudness, and other psychoacoustics measurements.
