The standard method to determine the output level of acoustic and mechanical stimulation to the inner ear is measurement of vibration response of the stapes in human cadaveric temporal bones (TBs) by laser Doppler vibrometry. However, this method is reliable only if the intact ossicular chain is stimulated. For other stimulation modes an alternative method is needed. The differential intracochl...

Audiogram: A graph of hearing ability charting frequency (abcissa) vs. sensitivity measured as sound pressure or intensity (ordinate). Cetaceans: Whales and dolphins decibel (dB): a scale based on the log ratio of two quantities. It is commonly used to represent sound pressure level or sound intensity. The value of the decibel depends upon the denominator used, or reference pressure. Therefore ...
