How Does Mercedes-Benz PRE-SAFE® Sound Work?

As part of the comprehensive Mercedes-Benz PRE-SAFE® suite, PRE-SAFE® Sound is activated if your vehicle detects that a collision is unavoidable. In such scenarios, PRE-SAFE®Sound will activate your Mercedes-Benz vehicle's sound system and play a short interference signal. Called "pink sound" or "pink noise," this interference signal deploys at about 80 decibels, which is roughly equivalent to the level of noise at the side of a busy road. This signal will cause a reflex in your ear to activate, protecting the eardrum and reducing the damage loud noises produced by the crash can cause to your hearing.

How Does Mercedes-Benz PRE-SAFE® Sound Protect Hearing?

PRE-SAFE® Sound protects hearing by triggering the stapedius reflex. This reflex causes the stapedius muscle to contract, weakening the connection between the ear drum and the inner ear for a split second. In essence, this causes some sound pressure to be reflected in the ear drum rather than transmitted all the way through to the inner ear. This helps mitigate hearing damage caused by high acoustic pressure or loud noises.

What Vehicles Come Equipped with PRE-SAFE® Sound?

PRE-SAFE® Sound is currently available in some 2017 Mercedes-Benz E-Class models. The Mercedes-Benz PRE-SAFE® system as a whole is available across a wide range of Mercedes-Benz models, from the Mercedes-Benz A-Class to the S-Class.
