The basilar membrane in the cochlea of the inner ear vibrates in response to different frequencies of sound. Different parts of the basilar membrane vibrate depending on the pitch of the sound waves, allowing us to perceive different frequencies as different pitches.

What determines the highness or lowness of a sound?
The frequency of a sound wave determines the pitch of the sound. Higher frequency waves produce higher-pitched sounds, while lower frequency waves produce lower-pitched sounds. The pitch is perceived by the human ear based on how rapidly the sound wave vibrates.
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! :)
How does sound from a radio get to your ears?
Sound from a radio is produced by the speaker in the radio itself, which vibrates to create sound waves. These sound waves travel through the air as pressure waves until they reach your ears. The vibrations are then detected by your ear's cochlea, which processes the sound and sends signals to your brain for interpretation.
Which interaction helps to explain why windows rattle when certain notes are played on an organ?
When certain notes are played on an organ, the sound waves created can match the natural frequency of the structure of the windows, causing them to resonate and rattle. This phenomenon is known as sympathetic vibration, where the window responds to the sound waves by vibrating at the same frequency.
Which part of the human ear vibrates?
The eardrum (tympanic membrane) vibrates in response to sound waves entering the ear canal. These vibrations are then transmitted to the small bones in the middle ear, which in turn amplify and transmit the sound to the inner ear for further processing.
Which part of the ear vibrates at the frequency of sound waves?
The eardrum
The function of the eardrum in the middle ear is to A- carry the sound energy to the brain B- collect the sound waves C- amplify the received sound D- vibrate with the frequency of the received sound?
D- The eardrum in the middle ear vibrates with the frequency of the received sound. These vibrations are then transmitted to the small bones in the middle ear, which amplify and transmit the sound to the inner ear for further processing.
What type of sound is produced when a string vibrates quickly?
A high-pitched sound is produced when a string vibrates quickly. The frequency of the vibrations determines the pitch of the sound.
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?
Vibrations are what create sound in the first place. When an object vibrates, it creates variations in air pressure which we perceive as sound. The frequency, or speed, of the vibrations determines the pitch we hear.
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.
What is energy that vibrates and you can hear?
Sound energy is a type of energy that vibrates and can be heard. Sound waves travel through a medium, such as air or water, and are detected by our ears. The pitch and volume of the sound are determined by the frequency and amplitude of the vibrations.
Why the harmonics are multiples of fundamental frequency?
Harmonics are multiples of the fundamental frequency because they are integer multiples of the base frequency. This occurs because when a sound wave vibrates at a fundamental frequency, it also vibrates at higher frequencies that are multiples of the fundamental frequency due to the physics of wave propagation. The presence of harmonics gives each sound its unique timbre or tone quality.
When an object vibrates slowly what dose it produce?
When an object vibrates slowly, it produces low frequency sound waves. These waves have a lower pitch compared to fast vibrations.
Wave in which frequency changes to create sound?
The frequency change that creates sound is known as a sound wave. Sound waves are created when an object vibrates, causing the air particles around it to move in a wave-like pattern. The frequency of these waves determines the pitch of the sound we hear.
Which structure is a fluid-filled cavity that vibrates when sound waves strike it?
cochlear duct
Most musical instruments produce sound by having a structure that vibrates linked to a?
Resonator
