What is the relative frequency of a sound as perceived by a listener?
I think you mean pitch.
How does sound affect frequency?
The definition of sound is : "Vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear." Sound can be measured by amplitude (loudness) and pitch (The frequency of the vibrations). Therefore sound does not affect frequency but frequency affects the pitch of the sound.
What happens to the ear drum when a sound hit's it?
Basically the ear drum vibrates and causes the three small bones in your ear to vibrate. The vibration of the last bone causes vibration on the oval window of the Cholea, the oval window vibrations cause the fluid within the semi circular canal to travel back and forwards over the basilar membrane. This is linked to neurones which take the information of which frequency you are hearing to the brain. So the vibration frequency of the ear drum depends on what pitch of sound you hear so the best thing to say would be. The frequency of vibrations increases with high pitched sounds and decreased with low pitched sounds.
Is the sound gathered and focused on the outer ear?
yes and no, When you hear a bark how do you know it is a dog? How do you recognize the sound as different from the phone rining or a song on the radio? Sound is captured by the ear and interpreted by the brain. The ear is made of three parts - the outer ear, middle ear, and inner ear. The outer ear is responsible for capturing sound waves. Once captured, the sound waves travel through the ear canal and vibrates the eardrum. Three tiny bones in the middle ear, called the hammer (malleus), the anvil (incus), and the stirrup (stapes), carry the vibration to the inner ear. A spiral structure called the cochlea changes the vibrations into electrical impulses, which are carried to the brain through the auditory nerve. A special area of your brain called the auditory cortex interprets and identifies the sound.
How many moving parts are in the human ear?
The middle ear, outer ear, and inner ear are the three parts of the ear.
What is how the ear perceives frequency?
Loudness
What is the lowest frequency a human can ear?
20Hz
Can the ear distinguish two pure tones having the same frequency and amplitude?
No, the ear cannot distinguish two pure tones having the same frequency and amplitude.
How does your ear respond to different sounds?
The ear responds logarithmically to different sounds. The ear which is divided into inner ear, outer ear and middle ear responds differently according to sound frequency and intensity.
Frequency response of the human ear?
The average response of a human ear at the ear drum is flat to about 500 Hz with a peak around 2.5KHz.
Which part of the ear vibrates at the frequency of sound waves?
The eardrum
What is the beat frequency sensible for human ear?
7 hz
What is tone in ear?
Tone is a pure sound. Typically, a fixed frequency makes a single tone. In the ear (human) a tone stimulates (there are restrictions) only one part of the ear. What is tone in ear?
How does the frequency of light compare to the frequency of sound?
-- The highest frequency of sound audible to the human ear is of the order of 20,000 Hz.-- The lowest frequency of light visible to the human eye is of the order of 375,000,000,000,000 Hz.
What is the lowest frenquency that humans can hear?
The lowest frequency that the human ear can detect is that of 20Hertz.
What is the properties of ultrasonic sound waves?
They have a frequency of above 20,000Hz inaudible to human ear.
Why did the Aztecs gauge their ears?
The Aztecs practiced ear gauging as a form of body modification and adornment, considering it a sign of beauty and status. Larger ear gauges were associated with higher social status and spiritual significance in Aztec culture.
