Sound Level Measurement
Class 1 Sound Level Meter for Sound and Noise Level Measurement
NVH Testing (Noise, Vibration, and Harshness)
Major manufacturers all around the world rely on Dewesoft NVH measurement systems for optimizing the interior and exterior noise, vibration, and harshness characteristics of their vehicles. Our DAQ systems offer full support for microphones and accelerometers for measuring and analyzing NVH data, all compliant with international standards and supported by calibration services. High bandwidth recording is combined with advanced software tools, including FFT analysis, order tracking, modal analysis, sound quality/level/power/intensity, and octave band analysis. Specific tests like pass-by noise, RT60 reverberation time, brake noise, and human-body vibration analysis are also supported.
