Noise emissions and immissionsNoise emissions and immissionsEstimation of noise emissions and immissions of machines and devices in special sound chambers and in operation.
Anechoic / Semi-anechoic chamber:
  • meets the requirements of EN ISO 3744, EN ISO 3745
  • background noise level 50 Hz – 20 kHz / <16 dBA
  • the chamber may be configured as anechoic or semi-anechoic
  • designed to measure sound pressure and determine sound power
  • measuring system B&K PULSE with parallel measurement in 12 measuring channels
  • frequency range 20 Hz – 20 kHz
  • fractional octave frequency analysis and real-time FFT analysis
  • recording of measured data and post-processing
  • possibility of simultaneous measurement of various physical quantities during measurement (noise, vibration, speed, voltage, etc.)


Reverberation chamber:
  • meets the requirements of EN ISO 3741
