Capture what motorcycle drivers actually hear. Accurately and realistic.

Capture what drivers actually hear.

Accurate. Realistic. Reproducible.

What matters are the sounds motorcyclists hear right next to their ears. With the BMK binaural microphone kit from HEAD acoustics, you capture exactly that—and nothing else—on every motorcycle test ride.

Optimize every acoustic test ride

The Binaural Microphone Kit (BMK) enables comfortable, reproducible binaural recordings during motorcycle test rides. Installed by HEAD acoustics in the SHOEI motorcycle helmet GT-Air 3, it captures exactly the sound riders perceive directly at the ear, avoiding the drawbacks of conventional in-ear microphone setups. Many existing solutions compromise usability, wearing comfort, and repeatability. The integrated BMK ensures consistent microphone positioning and helps test riders focus on the road while engineers receive reliable acoustic measurement data.

BMK helps overcome common challenges in motorcycle acoustic testing:

drastically enhanced handling
increased reproducibility through fixed microphone positioning close to the rider’s ears
much more realistic auditory feedback

Motorcycle acoustic testing made easy

Mount a mobile data acquisition system from HEAD acoustics—such as SQuadriga III or SQobold—to the motorcycle and use the BMK built into a Shoei MH I.x motorcycle helmet to capture binaural recordings directly at the rider's ears.

The setup enables realistic, hassle-free data acquisition under real-world riding conditions and helps address acoustic challenges such as rider comfort, sound quality, wind noise, and other motorcycle-related assessments.

Hear your ride as it truly is ...

... directly on-site with our unique binaural playback opportunities! You may even share your impressions with others using the binaural headset BHS II, which is automatically configured and equalized. It plays back your sound files at the scene for immediate evaluation while connected to your mobile measuring system.
