Noise test benches for vehicle homologation, Product Sound Design and more Pass-By measurement conform to DIN ISO 362-1:2017-10 is a standard method for all approved vehicles, but the same installed test benches are suitable for the design of e-vehicle sound. There are real pass-by test benches in weatherproof outdoor installations with two obligatory measurement microphones on one hand and on the other hand there are indoor simulation pass-by test stands with up to 64 microphone channels in very large indoor facilities with acoustic elements and room-acoustic installations, which allow a measuring limit, covering a range from 40Hz to 20kHz and more. That requirement for the low frequency limit came from combustion engines, but it’s usable for sound design in the e-mobility world too. MTG provides a wide range of innovations for sound-engineers, designing the noise of conventional and e-vehicles, including both single measurement tools and turnkey indoor test benches for simulated pass-by and outdoor pass-by test bench systems. The legally prescribed analyses and the balance between comfort and sportiness can only be achieved by using high-performance acoustic measuring and testing technology. Of essential importance here are exterior and interrior noise measurements. This applies to the area of vehicle homologation, as well as to R&D, optimization and production-side quality assurance, including the product sound design the of vehicle noises. The range of services includes complete project planning, procurement, installation, commissioning, instruction and customer service for all components by experienced Microtech specialists worldwide.
