AKUVIB offers a standard-compliant environment for measurements of acoustic properties in a low-reflection room

AKUVIB offers the possibilities to investigate single components up to complete vehicles in our semi-anechoic chamber .

With a noise level of less than 25db(A), various measurements of accuracy class 1 can be performed even on quiet components.

In addition to acoustic measurements of vehicles in idle, stand-up or cold start measurements, investigations of functional noise as well as actuation noises are possible in the vehicle or on individual components.

Furthermore, we perform modal analyses on components up to analyses of complete vehicle bodies by means of laser measurement technology and hammer excitation.

In addition to a semi-anechoic chamber, we also have the possibility to evaluate the sound power of machines or components in our reverberation chamber with measurements.
