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.
Same pitch but with different loudness
To alternate between constructive and destructive interference requires different frequencies.
The cochlea converts vibrations into electrical sounds
Tympanic membrane --> malleus --> incus --> stapes --> oval window --> cochlea
The cochlea is the part of the inner ear that takes vibrations, transferred from sound waves hitting the eardrum (tympanic membrane) and converts them into signals for the auditory nerve. Different parts of the cochlea "encode" different frequencies (pitches) of sound. Therefore, if only part of the cochlea is damaged, a person may lose the ability to hear certain frequencies of sound. If it is damaged enough, the person may lose the ability to hear completely in one ear.
cochlea of ear perceive and respond to various frequencies in sound...
the cells of the hairs don't detect the sound waves at all. The full hair is vibrated by the sound waves and this vibration is picked up by nerves and the info is sent to the brain.
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.
No. The frequencies determine the sound.
Different wavelengths and frequencies of light are interpreted as different colours; those of sound are interpreted as pitch.

The inner ear contains the receptors for sound which convert fluid motion into action potentials that are sent to the brain to enable sound perception. The airborne sound waves must be transferred into the inner ear for hearing to occur.
The receptors for sound are the 'cilia' ... tiny hairs that line the inner surface of the cochlea in the inner ear. Sound vibrations are directed into the cochlea by means of the eardrum and the bones of the middle ear, where the cilia move mechanically and excite the nerve endings to which they're attached.
no
Simply because the human ear can detect many thousands of different frequencies (typically 50Hz to 20,000Hz) Testing someone's hearing ability over a range of frequencies determines whether they can hear the normal spectrum of sound or not. As we get older - our hearing starts to fade - and we no longer hear the higher or low frequencies at the edge of the normal range.
The cochlea; sound wave are transferred through the ear canal and vibrated the ear drum which is connected to the cochlea and amplified the sound wave. When the sound wave reached the cochlea, sound wave is converted into nerve impulse and transferred through the nerve to the brain. Receptor is a converter of stimulus to electrical nerve impulse ; cochlea converted sound wave into nerve impulse and so cochlea is the sensory receptor of the ear.
