About This Product
■ Overview
The strength of binaural recording is to accurately capture the sounds heard by the subject to reproduce the 3D stereo sensation. In this way, all the listeners can regenerate recording and have the opportunity to experience the sound over and over again from the best seats.
The binaural microphone 4101-B type and the 4965-B type are designed so that the subject can be attached comfortably for the purpose of binaural recording. These products will provide listening and regeneration solutions if they are measured using a Bruel Care Sonoscout ™ NVH recorder. You can also add a CCLD conditioning detector and use it as a collection for other purposes.
■ TEDS
The binaural microphone has a transduca electronic data sheet (TEDS). This means that the individual information and load sensitivity of the left and right microphones are programmed in the TEDS memory, making it very easy and secure.
■ Calibration
Micro hons are selected based on the compatible frequency response. When used in the open ear canal of the subject, the binaural microphone is calibrated with a 4128 -inch head andtro simulator with an open ear canal.
The calibration value when used in the diffusion sound field is measured by the 4128 type Hats attached to the binaural microphone placed in the diffusion sound field. The response characteristics in front of the front 0 ° direction in the free sound field are also measured in the same way, but the measurement is performed in an adverse room. In both cases, the method of attaching the binaural microphone to the 4128 type is changed, and the average results can be obtained on average. The resulting data is included in Sonoscout.
