The middle ear transmits sound efficiently from the air in the ear canal (EC) to the fluid filled cochlea. In gerbil, middle ear transmission produces a constant pressure gain between the EC and the cochlea of ∼25 dB from 2 to 40 kHz, and a delay-like phase corresponding to a ∼25-30 μs delay. The mechanisms by which the air-born signal is collected and delivered to the cochlea are not thoroughly understood, and the source of the delay is controversial. We investigated these issues by observing… CONTINUE READING
