The PRE-SAFE® system makes use of the time prior to an impending accident on your behalf. A host of measures are able to reduce the loads generated as a result. The innovative PRE-SAFE® Sound system generates a sound from the speakers and is thus able to trigger a protective reflex in our bodies: our hearing briefly disengages to protect itself from loud crash sounds.

(I wonder what evidence they have of this actually doing what they claim.)
- cdot2 3y agoHow would you test that?
- tpmx 3y agoBy testing the hearing of people after accidents with and without this system. I guess you could also do testing on people who buy vehicles with and without this system - before any accidents.
- throw0101b 3y ago> When presented with an intense sound stimulus, the stapedius and tensor tympani muscles of the ossicles contract.[7] The stapedius stiffens the ossicular chain by pulling the stapes (stirrup) of the middle ear away from the oval window of the cochlea and the tensor tympani muscle stiffens the ossicular chain by loading the tympanic membrane when it pulls the malleus (hammer) in toward the middle ear. The reflex decreases the transmission of vibrational energy to the cochlea, where it is converted into electrical impulses to be processed by the brain. * https://en.wikipedia.org/wiki/Acoustic_reflex https://en.wikipedia.org/wiki/Acoustic_reflex
