Which cranial nerve innervates four of the six extraocular muscles? Which skeletal muscles are innervated by the facial nerve? In which part of the ear is the eardrum located? What structures does the auditory tube connect? What cranial nerve is the auditory nerve?
The eardrum is next to the head, which understands it all sound.In Opal's ear, that signal doesn't get properly sent to her head because the hair cells inside her eardrum were born lost. This loss was caused by a family gene(基因缺陷). A new treatment, called the ear treatment, is...

Method for improving the effectiveness of existing hearing aids. Method works by adjusting the negative pressure between an ear matching piece and the eardrum. The wearer is able to adjust the pressure himself so that the eardrum is kept in a tensioned condition and hearing is improved.KLEIN ...
eardrum symphony: is formed by a metallic structure with the base 2 and a soft tirante, driven by a pedal, which is to provide a membrane, which is at leas... Reflections in the first 50 ms are often assumed to enhance sound quality, but data supporting the assumption are lacking. We...
The first is leakage, or how much sound escapes before reaching the eardrum. Another is frequency response, or the extent to which the headphones can reproduce the full range of audible frequencies, from squealing treble to rumbling bass. Though you can achieve a high-fidelity experience with ...
It does this by vibrating rapidly in response to the vibrating voice coil, much the same way the three bones of the ear vibrate in response to the movement of the eardrum. The vibration of the voice coil is made possible by two fundamental properties of magnetism: Identical magnetic poles ...
Untreated chronic ear infections can alsocause tears in the eardrum. These tears will typically heal within a few days, though in more extreme cases, surgical repair might be required. The other primary risk of leaving an ear infection untreated is that the infection could spread beyond the ear...
The semi-open acoustic back cavity structure can also balance the air pressure and eliminate the pressure of the eardrum, thereby achieving a more relaxed and comfortable listening performance. In terms of units, Feiao FD3 uses a 12mm diameter moving coil unit, which also has a magnetic flux ...
As we said in our review of the original LinkBuds: “The heart-pounding lows on Busta Rhymes’ “Put Your Hands Where My Eyes Could See” are light taps against the eardrum, while the ferocious bass riff on Metallica’s “For Whom the Bell Tolls” left much to be desired.” Compare ...
