In-situ Sound Absorption testing

A truly in-situ method to measure the properties of your material​s

Acoustic noise pollution can be reduced by absorbing sound energy. Absorbing material packages are used in many applications to attenuate sound. Knowing exactly the acoustic properties of your materials and the effectiveness of the applied acoustic treatment is a requirement to successfully reduce noise levels. The In-situ absorption setup is a solution to achieve just that.

POINT, MEASURE, AND DIRECTLY OBTAIN SOUND ABSORPTION IN MINUTES

With a small, handheld impedance gun the sound absorption, reflection, and acoustic impedance can be measured in just a few minutes, broadband. With a sound source at 23cm from the probe, noise is generated toward the sample. The impedance gun is equipped with a system designed to decouple the sensors from structure-born vibration generated by the spherical loudspeaker. The sound pressure and acoustic particle velocity are measured directly on the surface of the material. The sound absorption & reflection coefficients can be obtained directly from the measured acoustic impedance as the complex ratio of sound pressure to particle velocity.

Non-destructive testing and truly in-situ

With our innovative in-situ absorption setup, the days of destructive testing are now behind us. This powerful system allows for the measurement of sound absorption in any environment, offering unprecedented versatility. Beyond testing simple material samples, the system is equipped to handle inhomogeneous materials, curved surfaces, and fully assembled parts.
