Testing

Noise 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
  
• background noise level 50 Hz – 20 kHz / <16 dBA
  
• suitable for determining sound power, determining the coefficient of absorption of sound-insulating materials and measuring the sound-insulating properties of products
  
• frequency range 20 Hz – 20 kHz
  
• measuring system B&K PULSE with parallel measurement in 12 measuring channels
  
• fractional octave frequency analysis and real-time FFT analysis
  
• recording of measured data and post-processing
