vehicle pass-by noise Software

To help reduce traffic noise, regulators set pass-by noise limits for each type of ground vehicle that must be met before a vehicle is allowed on public roads. Whether you are performing a pass-by noise test outdoors on an ISO-compliant test track, or indoors on a chassis dynamometer in a large hemi-anechoic chamber, our user-friendly pass-by software with built-in standards and regulations covers the full range of drive-by testing. Our indoor pass-by software connects directly to the outdoor pass-by noise database to enable tyre noise correction for type approval in compliance with the ISO 362-3 standard.
