The 2017 Mercedes-Benz E-Class is reportedly offering tons of advanced tech to appeal more to buyers in these changing times. These are designed to provide more convenience, safety, navigational and performance updates to future Mercedes owners.

Recently, we highlighted the Parking Pilot System of the brand that aim to unlock a new feature that would allow users to park their cars automatically with their smartphones. Alongside that tech is the Pre-Safe Sound.

Last time, not so much information was available about that particular safety feature. Thankfully, Wired shed more light to it.

As we mentioned earlier, the Pre-Safe Sound system prevents occupants of the car from having hearing damage due to a loud noise upon a collision to another object. According to the source, when the onboard sensors of the car detects that an impact is highly probable, it triggers a sound from its stereo. That sound comes in a static-type noise with levels up to 85 decibels. The sound is not loud enough to hurt the ears, but it conditions it for the louder sound that will be produced by a strong impact.

The Pre-Safe Sound lets the middle ear react early by triggering an acoustic reflex. This will make the stapedius muscle contract in order to effectively block the very loud noise that is a result of the crash, thus, minimizing damage to the more sensitive parts of the ears.

The function may also serve as an early warning mechanism that will alert the driver of the car if there is an imminent collision, giving him or her a split-second chance to avoid it.
