Noise is playing an increasingly important role in the development of new technical products and is having a greater influence on end customers’ purchasing decisions. Electric vehicles, for example, are significantly quieter as the combustion engine is no longer one of the dominant noise sources.
The noises of other vehicle components now come to the fore, which were previously masked by the noise of the combustion engine. These are now often perceived as annoying.
NVH tests (Noise, Vibration & Harshness) are used to study the noise emissions of vehicles and their components. The causes can then be identified and eliminated. Vibroacoustic measurements are used to measure and analyze the structure-borne noise (tangible vibrations) and airborne noise (audible vibrations) emitted into the environment.
Would you like to investigate the vibroacoustic properties of your products? We can measure and analyze the noise generated by products. In our acoustic chamber, we use special measurement technology to record the airborne and structure-borne noise emitted by a product. The acoustic chamber largely fades out ambient noise and provides a low-reflection test environment. We use microphones, accelerometers or laser vibrometers for the measurements. Excitation is provided by a low-noise shaker or by the functional operation of the test object.
