Acoustic systems

The majority of acoustic tests are performed in reverberation chambers. In this case, the specified acoustic pressure levels are formed in the acoustic chamber in a minimum time. Сontrol by power spectral density (PSD) of acoustic pressure is implemented.
The system provides the following control strategy:

  • at the maximum PSD of the acoustic pressure;
  • according to the average PSD of acoustic pressure;
  • the control system makes it possible to generate acoustic pressure levels in the volume of the acoustic chamber from 31.5 Hz to 8 kHz.

Software suite

The package is intended for adjusting of the controller in the systems for sound pressure levels generation and vibration control systems. Controller with this package allows controlling the sound pressure and perform analysis of the data from the vibroacoustic transducers.

 

Features and

Benefits

Load up to 160 dB

To reduce the time to enter the specified test mode, the control system takes into account data on the reverberation time of the acoustic chamber

To correctly digitize the signal of the measuring path, preliminary anti-aliasing filtering is implemented, while ensuring the synchronicity of signal conversion in all channels
