However, it's been argued that despite waves the microwave auditory effect only constituting a rapid 10 −6 °C rise in temperature, for threshold peaks on each pulse, that, at the least, a strong peak of around 1400 kW/cm² (1.4 billion mW/cm²) would certainly be harmful due to the resulting pressure wave.
In humans, sound waves funnel into the ear via the external ear canal and reach the eardrum (tympanic membrane). The compression and rarefaction of these waves set this thin membrane in motion, causing sympathetic vibration through the middle ear bones (the ossicles : malleus, incus, and stapes), the basilar fluid in the cochlea, and the hairs ...

The Outer ear consists of the pinna or auricle (visible parts including ear lobes and concha), and the auditory meatus (the passageway for sound). The fundamental function of this part of the ear is to gather sound energy and deliver it to the eardrum. Resonances of the external ear selectively boost sound pressure with frequency in the range 2 ...
[62] [49] This model extracts the temporal envelope of the sound (ENV p) via bandpass filtering, half-wave rectification (which may be followed by fast-acting amplitude compression), and lowpass filtering with a cutoff frequency between about 60 and 150 Hz. The leaky integrator is often used with a decision statistic based on either the ...
Scientists successfully filmed sound waves in a diamond crystal structure for the first time ever using an X-ray free-electron laser (XFEL).
Through the mechanisms of compression and rarefaction, sound waves travel through the air, bounce off the pinna and concha of the exterior ear, and enter the ear canal. In mammals, the sound waves vibrate the tympanic membrane , causing the three bones of the middle ear to vibrate, which then sends the energy through the oval window and into ...
The stapes transmits sound waves to the inner ear through the oval window, a flexible membrane separating the air-filled middle ear from the fluid-filled inner ear. The round window, another flexible membrane, allows for the smooth displacement of the inner ear fluid caused by the entering sound waves.
