USE SCENARIOS

  • Recording vehicle noise for sound quality evaluation and testing
  • Recording noise from domestic appliances, office equipment, etc., for sound quality optimisation
  • Recording noise from sub-suppliers’ products and components to evaluate and optimise their sound quality
  • Evaluation of headphones, and hearing protectors where a blocked ear canal is desired
  • Binaural sound and music recording
  • In-vehicle NVH recordings using Sonoscout Type 3663

The recorded signals from Types 4100 and 4100D can be modified using a wide range of time/frequency domain editing techniques using a sound quality software program and a PC. The modified signals can then be compared with the original in a listening test. If the modified signal is preferred, information on the changes in the noise can be used by the Product Designer to obtain – by physical changes – improved sound quality.
