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.
  • Load up to 160 dB
  • 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
  • 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
