- If there are uneven pressures, the eardrum can not vibrate normally and thus hearing may become impaired to various degrees, depending on the degree of pressure discrepancy. (mskneurology.no)
- On the contrary, inadequate pressure may cause excessive mobility of the eardrum, making it more sensitive to imposed vibration. (mskneurology.no)
- To hear properly, the pressure on both sides of your eardrum must be equal. (kidshealth.org)
