Type 4965-B is designed for automotive and ground vehicle applications. It is intended to provide a complete listening and playback solution for use with Brüel & Kjær’s Sonoscout™ NVH Recorder. However, with any CCLD conditioning, they can also be used in other sound recording scenarios.
- Binaural recordings at the entrance to the human ear canal
- Sound recordings where a vehicle driver wears the binaural microphone
- Binaural recordings where the influence of the test subject’s head and torso is important
- Sound recordings of a helmeted test subject, such as a motorcycle driver
- Psychoacoustic experiments requiring binaural sound recording on human subjects
- Binaural recordings where the use of a traditional HATS, for example, Sound Quality Head and Torso Simulator Type 4100, is impossible
- Evaluation of headphones and earmuffs on a human subject
- Benchmarking vehicles for reference or processing into simple PULSE™ NVH Vehicle Simulator models
- Capturing vehicle behaviour during on-road evaluation or while using DTS On-Road Simulator
- Cabin noise measurements
- As general-purpose two-channel data recorders
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.
