BSWATECH Beijing Reputation Portable Binaural Recording System PRO 750 Binaural Recording Microphone

This system can replace the traditional expensive artificial head system, using high-quality playback headphones with binaural microphones, high-resolution dual-channel data acquisition cards and Apple devices installed with APP recording analysis software. 3D audio recording and sound quality analysis can be performed at NVH and other test sites; At the same time, the recorded files are saved in .wav format (the attachment is the sound effect recorded with 3D Mic), which can be played back, or transmitted from the scene to the computer using the remote transmission function of Apple devices e-mail, etc.) Experts perform data analysis. Binaural recording is the most commonly used tool for NVH engineers. It can truly restore the noise in the car and provide a powerful tool for sound quality research and improvement. However, binaural recording usually requires expensive artificial heads, which are inconvenient to use. The biggest problem is that it cannot be used for testing in the driver's position, which is usually the position that customers are most concerned about. Binaural microphone is a popular recording equipment in recent years. Its price is much lower than that of artificial heads. It is easy to use and has a good reputation. The newly launched iBinauralMic Pro 750 combines the advantages of similar products on the market and focuses on measurement applications. Its features: 1) Use the reputation MPA416 measurement microphone (optional with TEDS) and perform binaural phase matching; 2) Calibration uses the same method as a microphone and can be transferred to a 1/2 calibrator; 3) The playback headphones use closed monitoring-grade headphones to effectively isolate environmental noise. 4) Using ICP power supply BNC connector, it can be connected to commonly used data acquisition. 5) The playback uses German Ultrasone’s top professional monitoring headphones. 6) Separate cables for headphones and microphones, good versatility 7) Threaded fixed wind balloon is suitable for indoor and outdoor noise measurement Recording and playback Binaural recording usually requires complex acquisition hardware and software, and uses MC3322 two-in and two-out professional data acquisition. It is connected to PC, iPhone, iPAD, Galaxy S5 and other mobile phones, and the data is recorded directly to the mobile phone or PC, professional The digital acquisition ensures the quality of the recording. The format of the data is WAV. While recording, the recorded sound can be monitored in real time. data sharing Test drivers are usually not professional NVH engineers. When encountering noise problems, they need professional and feedback. The usual method is to bring back the recorded signals for analysis. This traditional method obviously cannot meet the needs of research and development. Reputation iBauranlMic uses iPhone recording software to directly upload data to SoundCloud, FTP and email addresses to complete real-time sharing of data. NVH engineers can hear and analyze sounds thousands of miles away in the office.
