courses.physics.illinois.eduto sound waves in the perilymph fluid. The bending of the stereocilia stimulates the hair cells, which in turn excite neurons in the auditory nerve. The neuron firing/impulse rate on the auditory nerve depends on both the sound intensity I and the frequency f of the sound – e.g. neurons do not fire on every oscillation cycle of frequency

www.mne.psu.edu• The sound intensity is proportional to prms 2 • Pressure and velocity are in phase (i.e. the impedance is real and = ρc) 5.7 SPHERICAL WAVE PROPAGATION If we have a point sound source (the physical dimension of the source is much smaller than a wavelength), the sound pressure will be constant anywhere on a sphere surrounding the source.
