BinauralMic PRO 750
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.
Binaural recording usually need a complex hardware and software. BSWA use the MC3322 for data acquisition hardware, it can connected to PC, iPhone, iPad, Galaxy S5 and other mobile device. The data can be directly records by mobile device or PC in wav format and the professional data acquisition hardware guarantee the quality of the recording. The real time monitoring also can be support when the recording is ongoing.
The test driver is usually not professional NVH Engineer, which need professional guidance and feedback when face the issue. The traditional method is taking back the recording data and analyzes it in laboratory. This method is obviously cannot meet the needs.
BinauralMic PRO 750 using iPhone recording app to share the data to weixin, Facebook, Twitter, Sound Cloud, FTP and email. NVH Engineer can heard the voice of a thousand miles away and analyzes it in the office.
