Welcome to the acoustique calculation according VDI 2081

Noise generation and noise reduction in air conditioning systems

With this program you can calculate generated noise and attenuation for components of a air-conditioning system according VDI 2081, July 2001. We made some simplification for easier use.

For example:
-input started at the noise source and ended in the room
-the cross section mean s a quadratic duct
-all input fields containing common values, but they are changeable
-previous data will be assumed
-the changing of the air volume flow will be calculated as junction
-after calculation you can select fitting Trox attenuator
