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.
Our new handheld acoustic camera offers you maximum flexibility when in real-time acoustically investigating vehicles, machines, devices and many more on-site and in the laboratory.Read more »
Muffler 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 »
Sound absorption meter AcoustiAdrienne
The sound absorption meter AcoustiAdrienne serves the nondestructive measurement of the sound absorption, sound insulation and the sound diffraction of a noise barrier on the basis of the Adrienne method described in DIN EN 1793-4 and DIN EN 16272-4, DIN EN 1793-5 as well as DIN EN 1793-6 and DIN EN 16272-6.
By means of an adapter, the sound absorption coefficient of a road surface according to DIN ISO 13472-1 in situ as well as the sound absorption coefficient of a noise barrier according to DIN CEN/TS 1793-5 can be determined nondestructively.
On the basis of the measuring results, the rated sound absorption coefficient according to DIN EN ISO 11654 of a wall absorber or ceiling absorber being installed in a room can be estimated as well.Read more »
