Sound Quality Head and Torso Simulator -
Type
4100
Sound Quality Head and Torso Simulators Types 4100 and 4100 D are manikins designed for sound quality testing.
The recorded signals from Types 4100 and 4100-D 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.
Uses
- 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
