Sound absorber software AcoustiCalc® Absorber
The sound absorber software AED 3001 – AcoustiCalc® Absorber is an effective tool for the acoustic design of multi-layer sound absorbers by simulating the sound absorption coefficient.
The working principle of the simulation software for sound absorbers is absed on the analytical description of the single layers of the sound absorbers as fourpoles according to the linear network theory.
By concatenation of open-cell material layers in combination with air gaps, the acoustic behaviour of arbitrary and multi-layer sound absorbers can be calculated simply and fast under defined environmental conditions.
By predicting results of measurements of sound absorption coefficient in the reverberation chamber and/or the Alpha cabin, already in the early stage of development time, money and material can be saved.Read more »
Acoustic camera AcoustiCam®
The acoustic camera AcoustiCam® is an efficient tool for localizing and seperating sound sources in no time.
Simultaneous measurement with a large number of microphones (microphone array) are carried out followed by subsequent processing of the recorded microphone signals through an analysis software.
To visualize the sound situation – as in the case of applying an infrared camera – a photograph of the test object is laid underneasth the localization result.Read more »
Silencer software AcoustiCalc® Silencer
The muffler software AED 8001 – AcoustiCalc® Silencer is a powerful tool for the acoustic design of single elements and complex systems of silencers and mufflers by simulating the insertion loss and the transmission loss.
The working principle of the simulation software for silencers is based on the analytical description of the specific elements of ducts and mufflers as quadrupoles according to linear network theory. All models correspond to the current state of the art and were additionally optimized by us by means of numerical simulations.
By concatenation of the single elements, the acoustic behavior of arbitrary and complete systems of mufflers can be calculated easily and fast with respect to defined operational conditions.Read more »
