For acoustic and impact sound analyses in automotive design and, in general, in mechatronic systems where drives or motors are involved, Goepel electronic GmbH has developed its SoundChecker system. The device offers a cost-effective entry to sound analysis.
The SoundChecker system consists of a measurement data collecting unit, structure-borne sound sensors or open air microphones and an installation software which can be run on each PC with USB interface. In addition, Goepel offers completely set-up PC systems with preconfigured impact sound measurement equipment.
The USB data acquisition module provides excellent transmission behaviour for sound signal detection, the vendor promises,. The system covers the frequency range from 5 Hz to 22 kHz and a dynamic range of up to 11 db at a sample rate of 51.2 kSa/s. Due to the high 24 Bit resolution the module is suitable to check for acoustic and mechanic vibrations. The integrated power supply (IEPE/ICP conformal) allows the direct connection of structure-borne sound sensors.
The operating software contains complex analysis processes for simple parameterisation of specific impact and airborne sound evaluations. SoundChecker can be synchronised and controlled via a common communication interface. Users may also install the software in parallel to their own applications to execute impact sound analyses.
