How Does the PRE-SAFE® Sound System Work?

Exploring the Innovative Technology of the PRE-SAFE® Sound System

Mercedes-Benz continues to lead the automotive industry with safety innovations designed to protect both body and mind. One standout feature is the PRE-SAFE® Sound System, a unique safety technology that prepares passengers for loud noises during certain collision situations. Emitting a specific sound before an impact helps reduce the risk of hearing discomfort or damage. This system is a perfect example of how Mercedes-Benz blends science with driving confidence.

What Is the Mercedes-Benz PRE-SAFE® Sound System?

The PRE-SAFE® Sound System is part of the broader Mercedes-Benz PRE-SAFE® suite, which anticipates and responds to potential accidents. This specific feature focuses on hearing protection. In the event of an impending collision, it uses the vehicle’s audio system to emit a short, pink noise sound. This sound triggers a natural reflex in the human ear called the acoustic reflex, which prepares the inner ear for sudden loud noises. The result is a reduced likelihood of experiencing temporary hearing issues after an accident.

The technology behind PRE-SAFE® Sound is grounded in human biology. A sudden, loud noise, such as the crunch of metal during a crash or the deployment of an airbag, can expose the inner ear to damaging sound levels. Mercedes-Benz engineers designed PRE-SAFE® Sound to take advantage of the stapedius reflex, a built-in defense mechanism that tightens the small muscle in the ear to limit sound transmission.

When the system detects that a collision is highly likely, based on data from sensors monitoring speed, brake pressure, and other vehicle dynamics, it instantly plays a pink noise signal through the speakers. This sound is specifically calibrated to stimulate the stapedius muscle without causing discomfort to passengers. Once triggered, this reflex reduces the energy transmitted to the inner ear, potentially lowering the impact of the loud crash sounds.

Unlike passive safety measures that react only after an accident, PRE-SAFE® Sound acts in the split seconds beforehand. This proactive approach is what sets it apart from traditional safety systems. It works harmoniously with other PRE-SAFE® features, such as seatbelt tightening and adjustments, to create a comprehensive protective environment for all occupants.
