HEAD Acoustics launches BMK binaural microphone helmet for motorcycle testing

HEAD Acoustics has introduced the BMK, the first binaural microphone system integrated into a motorcycle helmet. The company aims to improve accuracy and rider comfort during real-world acoustic test rides, addressing limitations of conventional in-ear measurement methods.

Key Highlights

• HEAD acoustics launches the BMK binaural microphone system integrated into the Shoei MH-I.x motorcycle helmet.
• BMK improves measurement accuracy and rider comfort compared to traditional in-ear microphones.
• System works with SQuadriga III or SQobold for real-world binaural sound recording.
• BMK supports immediate playback and evaluation of acoustic data at test locations.

BMK System Features and Benefits

The Binaural Microphone Kit (BMK) is built directly into the Shoei MH-I.x helmet. HEAD acoustics GmbH, based in Herzogenrath, Germany, developed the system to solve challenges in capturing precise sound data on motorcycles. Traditional in-ear microphones often compromise comfort and ease of use, leading to inconsistent data and reduced acceptance among test riders and engineers.

The BMK offers several advantages. It provides optimized handling for faster measurement setup. The system improves reproducibility, ensuring more consistent data collection. It also delivers more realistic acoustic perception during testing. The integration into the helmet allows for practical and user-friendly acoustic testing under real driving conditions.

Integration with Measurement Ecosystem

The BMK is designed to work within HEAD Acoustics' mobile measurement ecosystem. When paired with a mobile data acquisition system such as the SQuadriga III or SQobold, which can be mounted on the motorcycle, the BMK records binaural sound directly at the rider's ears. This setup enables analysis of various acoustic phenomena, including driving comfort, sound quality, wind noise, and other vehicle acoustic characteristics under real-world conditions.

In addition to recording, the BMK supports HEAD Acoustics' binaural playback tools. Using the automatically configured and equalized BHS binaural headset, test teams can listen to and evaluate recorded sound events on-site immediately after a test ride. This allows teams to share auditory impressions, discuss results, and make decisions directly at the test location.

Company Background and Global Reach
