BinauralMic PRO 750

Introduction

Binaural recording which can restore the real noise in the car is the most commonly used tool for NVH Engineer. It is a powerful tool for research and improvement of sound quality. Binaural recordings usually require expensive artificial head, and it’s not easy to use. The biggest problem is the test cannot carry out on the driver's seat that most of engineer and tester focus on. BinauralMic is popular in recent years recording equipment. The cost is very low compare to the artificial head and easy to use.
