Diver clearing ears Section of the human ear, the Eustachian tube is shown in colour. Ear clearing, clearing the ears or equalization is any of various maneuvers to equalize the pressure in the middle ear with the outside pressure, by letting air enter along the Eustachian tubes, as this does not always happen automatically when the pressure in the middle ear is lower than the outside pressure.
It is far more targeted, effective, and ultimately safer (the increased pressure exerted by the Valsalva technique can actually harm your ears).This procedure is easier to do and does not require as much oxygen as the valsalva maneuver. It is effective in depths of up to -80 meters and can be performed multiple times quickly underwater.
Normally, the air pressure in the ear canal is the same as ambient pressure. Also, under normal conditions, the air pressure in the middle ear is approximately the same as ambient pressure since the eustachian tube opens periodically to ventilate the middle ear and equalize pressure. In a healthy individual, the maximum sound is transmitted ...
The Valsalva maneuver may help check for a dural tear following certain spinal operations, such as a microdiscectomy. An increase in intra-spinal pressure will cause cerebral spinal fluid (CSF) to leak out of the dura, causing a headache. [citation needed] The Valsalva maneuver has been associated with transient global amnesia. [17] [18] [19 ...
Tympanostomy tube, also known as a grommet, myringotomy tube, or pressure equalizing tube, is a small tube inserted into the eardrum via a surgical procedure called myringotomy to keep the middle ear aerated for a prolonged period of time, typically to prevent accumulation of fluid in the middle ear.
Sound is transmitted to the inner ear via vibration of the tympanic membrane, leading to movement of the middle ear bones (malleus, incus, and stapes). Movement of the stapes on the oval window generates a pressure wave in the perilymph within the cochlea, causing the basilar membrane to vibrate. Sounds of different frequencies vibrate ...

The term debadging refers to the process of removing the manufacturer's emblems from a vehicle. Common emblems to be removed include the manufacturer's logo as well as the emblems designating the model of the vehicle. Often debadging is done to complement the smoothed-out bodywork of a modified car, or to disguise a lower-specification model.
