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! :)
Does In your inner ear different parts of the basilar membrane vibrate at different natural frequencies?
Yes. It is correct. In your ear different parts of the basilar membrane vibrate at different natural frequencies. You have stapes bone attached to oval window. When it vibrates, the vibrations are transmitted to round window. This transmission goes through scala vestibuli and comes back through scala tympani. This can happen because there is communication between to channels at the tip. When this fluid vibrates, the vibrations are taken up by different part of basilar membrane. For this you have to have the basilar membrane anatomically tapered. The longer part vibrates with low frequency sound and tapering part vibrates with sounds of higher frequencies successively. So the 'resultant' frequency is taken up by part of the basilar membrane. The signal is transmitted by hair cells to brain. With successive 'resultant' signals brain can analyse the hundreds of different sounds. Two ears together give stereoscopic effect to the sound.
How does the eardrum work?
the ear drum is a part of your ear which vibrates to send the sound onto the three small bones.
How does the cochlea work?
The cochlea is responsible for hearing and is filled with fluid. When the oval window vibrates the fluid in the inner ear moves around. The membrane inside the cochlea has different levels of thickness and the vibrations have different frequency and correspond to different pitches of sound that the ear interprets. The oval windows vibration frequency is transmitted through the fluid wave within the inner ear. The fluid crosses over the membrane, depending on the frequency and stimulates nerves that transmit a signal to the brain.
How does sound from a radio get to your ears?
sound gets to your ears by vibrations in the air. the radio sends the vibrations out of the speaker causing the air to vibrate, when the sound reaches the ear drum it makes it vibrate, allowing us to hear sound. Kieran Cash 15 years old :)
Which part of the ear vibrates at the frequency of sound waves?
The eardrum
What happens to the pitch of a note when the frequency is increased?
If the frequency of a sound is increased, the pitch goes higher.
How do vibrations affect sound?
a vibrating body produces sound. ie only if an object vibrates will it produce sound. the faster the object vibrates, the louder the sound and vice-versa. the no of vibrations per seceon is called frequency. thus if an object has a higher frequency, then it produces a louder and shriller sound...
How fast does a sound vibrate?
Every second, it vibrates once for every Hertz of its frequency.
What causes pitch to change?
Every sound vibrates with a particular fundamental frequency. When you change the wavelength of a sound, you change the pitch of a sound.
Which structure is a duct filled with fluid that vibrates when the sound waves strike it?
ear
A blade of grass vibrates at a frequency of 428 Hz. What is the period of the sound wave?
5 HTZ
Why does a glass break when a certain sound wave hits it?
The sound wave must match the glass's natural resonating frequency, which means the frequency that it vibrates naturally at, when the glass picks this up, it vibrates with it due to resonance. The glass can vibrate so violently that it shatters.
Most musical instruments produce sound by having a structure that vibrates linked to a?
Resonator
Which structure is a fluid-filled cavity that vibrates when sound waves strike it?
cochlear duct
What type of sound is created when a string vibrates rapidly?
It doesn't exactly make a different sound, it just creates a sound wave with a frequency that is very rapid.
What structure of a sound depends on the frequency of its own sound wave?
It's frequency, obviously, and also its wavelength. Its speed as well.
