Microwave Hearing Pathway
... The resonant frequency of the adult human skull is 1-2 kHz [18-20]. This is about one-tenth of the predicted brain resonant frequency of 11 kHz for microwave hearing in adults [3]. In the absence of data on animal skulls, we might expect a similar ratio between resonant frequencies of brain and skul ...

What is hearing loss?
... There are three types of hearing loss: 1. Conductive Hearing Loss: A conductive hearing loss means something is wrong with the outer ear or the middle ear. Some people are born without the pinna (the part of the outer ear that we can see) to catch sound. Others have a blockage of wax in their ear ca ...

Olivocochlear system
The olivocochlear system is a component of the auditory system involved with the descending control of the cochlea. Its nerve fibres, the olivocochlear bundle (OCB), form part of the vestibulocochlear nerve (VIIIth cranial nerve, also known as the auditory-vestibular nerve), and project from the superior olivary complex in the brainstem (pons) to the cochlea.
