A chassis dynamometer generates high noise levels, vibration and mechanical energy during testing. Without proper acoustic planning, this can affect the comfort of nearby staff, the reliability of measurements and the overall usability of the facility. A well-designed test room helps manage airborne noise, structure-borne vibration and reverberation while still allowing safe operation, access for maintenance and proper ventilation. In industrial settings, the final solution should always be based on an acoustic assessment, machine specification and the building structure.
