or tympanic membrane. The tympanic membraneis a thin tissue that divides your middle ear and outer ear canal. This membrane vibrates when sound waves enter your ear. The vibration continues ...

According to Siegle, the inventor of the pneumatic otoscope, initially there should be induced rarification (application of negative pressure) in the ear canal. When the tympanic membrane is ...

During the performance of the test, the air pressure in the sealed ear canal is varied by means of an automatic pressure pump. This examines the range of mobility of the tympanic membrane under ...

In an optimal testing situation, the ear canal should be clear and unobstructed to enable the transmission of acoustic energy (sound) and applied air pressure through the tympanic membrane ...

The test seeks to establish the condition and movement of the tympanic membrane as it responds to ... to changes in air pressure within the ear canal. ‌ When sound waves activate the eardrum ...

"Swimmer's ear is an infection of your outer ear canal, which is bone and cartilage covered by skin and runs from your tympanic membrane (ear drum) to the outside of your head," said Dr. Thompson.
