How are sounds of different frequencies differented in the cochlea?

The way I heard from a podcast about tinnitus, there are nerve hairs that wiggle in response to certain frequencies, and alerts the brain and adjacent nerve hairs, allowing you to "sift" through information.

How are sounds of different pitch differentiated in the cochlea?
Pitch discrimination results from the fact that the basilar membrane has different vibrational properties along its length, such that the base (nearest the oval window) vibrates most strongly to high frequency sounds, and the tip to low frequencies.
Is the cochlea and the eardrum the same thing?
No. The eardrum (also known as the timpanic membrane) is a membrane that helps amplify sounds. The cochlea is deeper inside the ear, behind the eardrum. It is like a tube with little tiny hairs that vibrate at different sound frequencies which transmit information to the brain to help us percieve sound at different tones and pitches.
Can different sounds be produced by sound waves with the same frequencies?
No. The frequencies determine the sound.
What converts sound vibrations into electrical impulses?
The cochlea converts vibrations into electrical sounds
Describe how sounds of different frequency pitch are differentiated in the cochlea?
Pitches are differentiated by the length and tension of the basilar membrane fibers.
Are high frequencies heard as deep sounds?
No, high frequencies are heard as high pitched treble sounds.
What part of the cochlea is affected by the bass singer?
high frequency sounds at base of cochlea. encounter sound first and deteriorate first
What sounds correspond to frequencies heard by humans?
I think what you mean is: What frequencies correspond to sounds heard by humans ?The answer to that one is different for every individual. A representative bandwidth for humansis commonly considered to be 20 Hz to 20,000 Hz.
How does a speaker vibrate at different frequencies at the same time?
An infinite number of sounds can be mixed together into a single sound wave. The different frequencies don't matter, unless they are specific frequencies that cancel each other out. You'll notice that, even though you have only two ears, you can still hear all those sounds at the same time.
How do sound different from each other?
Sounds differ by amplitude, frequency and number of frequencies contained in a sound.
Do particles make you hear sounds?
Not exactly- sounds are transmitted as vibrations in the air which are picked up by the cochlea in the inner ear. The cochlea contains tiny hair follicles which are attached to minute chalk granules called otoliths- these are made to vibrate by the soundwaves and send electrical signals up the auditory nerve, which the brain interprets as the many different sounds and noises that we hear.
What causes different piches in sound?
Different pitches of sound are caused by intensity, pitch, and tone. Intensity is the amount of energy a sound has over an area. This means the same sound is more intense if you hear it in a smaller area. In general, sounds with a higher intensity are louder. Pitch depends on the frequency of a sound wave - high sounds have high frequencies and low sounds have low frequencies. The quality of the sound depends entirely on the combination of different frequencies of sound waves.
