Sound and Vibration Measurements

The chair of Acoustics and Haptics has a large portfolio of acoustic measurement technology, as well as special acoustic rooms, such as

• a large anechoic chamber,
• an echoic chamber the
• the Multi-Modalen Measurement Laboratory.

To ensure the comparability of research results, the measurement environments are designed complying with recent standards. Besides the acoustic characterization and further development of the measurement subjects and materials, the optimization of known and development of new, innovative measurement methods is a field of activity of the chair.
