CAPABILITIES

Type 4965-B includes Binaural Microphone Type 4101-B plus a pair of bone-conducting, Bluetooth®-enabled headphones. This configuration is focused on NVH testing, where a person’s perception of sound is investigated and important to understand. The headphones are designed to be positioned next to the ears, thus giving the driver/passenger a perfect impression of the vehicle experience.
