Motorcycle Acoustic Measurement Technology Advances With HEAD Acoustics BMK Helmet System

A new development in Motorcycle Acoustic Measurement Technology has emerged with the introduction of the BMK (Binaural Microphone Kit) from HEAD acoustics GmbH. The company describes the solution as the first binaural microphone system integrated directly into a motorcycle helmet for acoustic measurement applications. Developed to improve the collection of sound data during motorcycle testing, the system is designed to overcome limitations associated with traditional measurement methods while enhancing usability for engineers and test riders operating in real-world conditions.

The company noted that conventional acoustic measurement approaches, particularly in-ear microphones, have often presented challenges related to rider comfort and ease of installation. Such limitations can affect measurement consistency and reduce acceptance among testing teams. To address these concerns, the BMK incorporates binaural measurement technology directly into the Shoei MH I.x helmet, creating a practical configuration that can be used during actual motorcycle operation without significantly affecting the rider experience.

Helmet-Integrated Design Targets Improved Acoustic Data Collection

According to the manufacturer, the integrated design delivers several operational benefits for acoustic testing programs. The BMK is intended to simplify handling procedures, reduce setup time, and improve measurement repeatability across test sessions. By positioning the microphones within the helmet structure, the system aims to provide a more realistic representation of how riders perceive sound while maintaining consistency during data acquisition activities.

The solution has been developed to operate as part of the broader measurement ecosystem offered by HEAD acoustics GmbH. When connected with mobile acquisition platforms such as SQuadriga III or SQobold installed on a motorcycle, the BMK captures binaural sound directly at the rider's ears. This configuration enables engineers to evaluate multiple acoustic parameters under real operating conditions while maintaining measurement precision throughout the testing process.

Support for Real-World Motorcycle Sound Analysis

The company stated that the system can be used to investigate a wide range of acoustic characteristics associated with motorcycles. Engineers can analyze driving comfort, perceived sound quality, wind noise behavior, and additional vehicle-related acoustic phenomena encountered during operation. Capturing data directly from the rider's listening position allows testing teams to obtain information that closely reflects actual riding experiences, supporting more detailed assessments of vehicle acoustics.

In addition to recording capabilities, the BMK is compatible with the company's binaural playback environment. Recorded sound events can be reviewed using the automatically configured and equalized BHS binaural headset, allowing teams to listen to measurement results shortly after completing a test ride. This approach supports rapid evaluation and facilitates technical discussions among team members at the testing location.

Frequently Asked Questions

What is the BMK system introduced by HEAD acoustics?
The BMK is a helmet-integrated binaural microphone solution developed specifically for motorcycle acoustic measurements. It incorporates microphones directly into a Shoei MH I.x helmet, allowing engineers to record sound at the rider's ear position under real-world riding conditions. The system is designed to improve measurement consistency, simplify setup procedures, increase rider comfort, and provide realistic acoustic data for evaluating sound quality, wind noise, and overall motorcycle acoustic performance.

How does the BMK improve motorcycle acoustic testing?
The BMK improves motorcycle acoustic testing by combining binaural recording technology with a practical helmet-based design. Unlike traditional in-ear microphone setups, it reduces comfort-related challenges while enabling repeatable measurements. When used with compatible acquisition systems such as SQuadriga III or SQobold, the solution records sound directly where riders hear it. Engineers can also replay recorded events immediately using the BHS binaural headset, supporting rapid analysis and decision-making at the test site.
