What do sound waves that reach the human ear cause?

Correct Answer:
forced oscillation of the eardrum


when sound waves reach the human ear, they cause the eardrum, or tympanic membrane, to experience forced oscillation. this phenomenon is a direct consequence of how sound waves interact with the ear's anatomy to produce the sensation of hearing.

sound waves are essentially fluctuations in air pressure propagating through the medium of air. as these waves enter the ear canal, they strike the eardrum, which is a thin, tightly stretched membrane that separates the outer ear from the middle ear. the varying pressures of the incoming sound waves push and pull on the eardrum, causing it to vibrate. this vibration is what is referred to as the forced oscillation of the eardrum.

the amplitude of a sound wave, which determines its loudness, naturally decreases as the distance from the sound source increases. this attenuation occurs because the energy of the sound waves spreads out over an increasingly larger area as they move away from the source. despite this decrease in amplitude, the energy that reaches the eardrum is still sufficient to cause it to vibrate.

the eardrum's vibrations are a response to the net force exerted by the sound wave. this force is the result of the difference in pressure between the wave's peak (compression) and trough (rarefaction) compared to the ambient pressure behind the eardrum. the eardrum effectively translates these variations in sound wave pressure into mechanical vibrations.

in summary, the key interaction that allows humans to perceive sound involves the forced oscillation of the eardrum induced by sound waves. this mechanical response to sound wave pressures is crucial for the subsequent steps in the hearing process, where these vibrations are converted into neural signals that the brain interprets as sound. this detailed understanding of the forced oscillation of the eardrum highlights its essential role in the auditory system.
