Even soft sound makes the eardrum vibrate.
It's the sound pressure deviation we measure as sound pressure level (SPL). The threshold of pain is known in acoustics as the lowest strength of a stimulus that is perceived by the ear as painful. Because of the different sensitivity of the hearing of people it cannot be given an accurate value. You can find the following rounded values for threshold of pain in various audio articles and books:
140 dB equivalent to SPL 200 Pa
137.5 dBSPL equivalent to 150 Pa
134 dBSPLequivalent to 100 Pa
130 dBSPL equivalent to 63 Pa
120 dBSPL equivalent to 20 Pa
Sound pressure levels more than 140 dB will let your eardrums burst.

∙ 10y agoWhen "a sound wave strikes", that means the pressure against the object rapidly
alternates between higher-than-normal-pressure and lower-then-normal-pressure,
several hundred times every second. The eardrum is a thin skin-like membrane,
and it moves in response to variations in the pressure against it. This is lucky for
us, because it's how we 'hear'.

∙ 12y agoSound waves make your eardrum vibrate, that is why we heard sound because the sound wave vibrates and allows us to hear sounds. :)

What vibrates in your ear before you hear sound?
Sound waves vibrate against your eardrum, hammer, anvil, stirrup, and cochlea.
Which structure is a duct filled with fluid that vibrates when the sound waves strike it?
ear
What do eardrums do when sound waves reach them?
The eardrums are like an omnidirectional microphone. The sound pressure vibrates the membrane (diaphragm) of the eardrum and the microphone only from one side.
A thin patch of skin in the ear that vibrates when sound waves strike it?
Ear Drum also known as the Typanic Membrane
What vibrates in response to sound waves?
Anything touched by the sound waves.
What is the thin membrane that vibrates when sound waves reach it?
The eardrum vibrates when sound waves reach it.
Which part of the ear vibrates at the frequency of sound waves?
The eardrum
What part of the ear vibrates when sound waves strike it?
The sound waves come through the auditory canal and hit the eardrum (or tympanic membrane). The eardrum is connected to the 3 ossicles of the middle ear: the hammer, anvil and stirrup (or malleus, incus and stapes). The eardrum vibrates the hammer, the hammer vibrates the anvil, the anvil vibrates the stirrup and the stirrup vibrates the cochlea in the inner ear which has hair-like nerve endings called cilia that move when the cochlea vibrates. The auditory nerve sends the vibrations to the brain to be interpreted. That's how we hear! :)

Which structure is a duct filled with fluid that vibrates when the sound waves strike it?
ear
How does the outer ear help you hear?
When your eardrum vibrates, it is responding to sound it has heard. Then, it send a signal to your brain telling your body to react.
Which structure is a fluid-filled cavity that vibrates when sound waves strike it?
cochlear duct
What part of the outer ear transmits sound by vibrating?
When a sound is made outside the outer ear, the sound waves, or vibrations, travel down the external auditory canal and strike the eardrum (tympanic membrane). The eardrum vibrates. The vibrations are then passed to 3 tiny bones in the middle ear called the ossicles. The ossicles amplify the sound.
Which structure is between the middle ear and the inner ear?
Sound waves hit the eardrum. The eardrum vibrates in response to the sound waves. These sound vibrations are amplified and transmitted by the auditory ossicles of the middle ear to the inner ear where they are changed into electrical energy and sent to the brain for interpretation.
What causes the auditory ossicles to vibrate?
The sound waves, coming through the auditory canal, strike the tympanic membrane (eardrum).The eardrum vibrates because of the soundwaves.This vibration is picked up by the ossicles and transmitted through the middle ear to the oval window.Therefore it is the soundwaves causing the eardrum to vibrate that ultimately makes the ossicles vibrate.
Why can't we hear when we have a lot of ear wax?
Because in order for us to hear, sound waves need to reach the eardrum - which vibrates - creating the sounds. Excessive earwax blocks the sound-waves reaching the eardrum, which reduces the volume of sounds.
What do eardrums do when sound waves reach them?
The eardrums are like an omnidirectional microphone. The sound pressure vibrates the membrane (diaphragm) of the eardrum and the microphone only from one side.
