... The middle ear transformer mechanism ensures that up to 50% of the incident sound energy is transmitted to the cochlea. This value is applicable for one frequency only i.e. 1 kHz. At other frequencies additional factors come into play. The malleus incudal joint is fixed in contrast to incus Stapedi ...

Auditory system
The auditory system is the sensory system for the sense of hearing. It includes both the sensory organs (the ears) and the auditory parts of the sensory system.
