Round‐window recordings were carried out to determine the range and sensitivity of the cochlear potential of the mouse. The range was found to be from 500 cps to greater than 40 000 cps. Two frequencies, 14 000 and 20 000 cps, had the lowest sensitivity. Sound pressures to give 0.5‐ and 1‐μV responses to all frequencies were determined. The input and output functions of the mouse cochlea were also determined. Studies were done on overloading in the mouse's cochlea. The eighth‐nerve action potential was recorded from the round window and from the eighth nerve. An N1N2 was observed. The mouse appears to be similar to other animals in respect to its cochlear dynamics and characteristics of the eighth‐nerve action potential.
