Sound absorber software AcoustiCalc^® Absorber

Schallabsorber-Software AED 3001 - AcoustiCalc® Absorber zur Auslegung von mehrschichtigem Schallabsorber

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. All models ar from the current literature.

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.

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.

Strömungswiderstandsmessgerät AED 300 - AcoustiFlow® zur messtechnischen Bestimmung des Strömungswiderstands von offenporigen Materialien

The airflow resistivity meter AED 300 – AcoustiFlow^® allows the determination of the airflow resistance of materials with open porosity on the basis of the direct-airflow method described in DIN EN 29053 (ISO 9053).

This technique requires the measurement of the pressure drop across the specimen to be examined as a function of the volume airflow.

The specific airflow resistance of a sound absorber mainly influences its sound absorption coefficient.

The Gesellschaft für Akustikforschung Dresden mbH acts in the various fields of acoustics and offers its clients an extensive range of services. These include acoustic measurements and the determination of material parameters as well as consultancy in all matters of acoustics and noise reduction more »
