What is "static pressure" in Hearing Science? <br><br> I will mark brainliest!
djverab [1.8K]

Answer:

It has long been known that static pressure affects middle-ear function and conventional tympanometry uses variations in static pressure for clinical assessment of the middle ear. Middle-ear under-pressures tend to reduce the velocity magnitude more than do middle-ear over pressures.

The effect of middle-ear static pressure on the acoustic response of both structures is similar in that non-zero middle-ear static pressures generally reduce the velocity magnitude of the two membrane components in response to sound stimuli.

Lastly, the skin's lipids maintain an acidic pH which slows and stops growth and replication of bacteria.
