Describe infrasonic and ultrasonic waves and explain why humans can not hear them?
The human ear cannot detect all possible frequencies. It has evolved to detect frequencies of sounds that are the most useful to humans, and has a maximum frequency range of about 20Hz to 20kHz, which decreases as you get older, particularly at the higher end. Infrasonic describes sounds that are too low in frequency to be heard by the human ear, and ultrasonic describes sounds that are too high in frequency to be heard by the human ear. These sounds cannot be heard by the human ear because they are outside of its range of capability.
What is the lowest frequency a human can ear?
20Hz
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.
What is the beat frequency sensible for human ear?
7 hz
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 organ in the perch fish is most closely related in function to a human's ear?
The lateral lines are most closely related to the human ear. They detect vibrations not sound.
What is the properties of ultrasonic sound waves?
They have a frequency of above 20,000Hz inaudible to human ear.
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?
At how many cycles per second does a human vibrate?
A human typically vibrates at a frequency range of 12-20 cycles per second, known as the human audible range. This range corresponds to the frequencies of sound waves that the human ear can detect as audible sound.
What frequency of waves in the air can be heard as an audible sound by the human ear?
For the human ear, sound is audible in the range of 20 Hz (Hertz) to 20000 Hz. Sounds below 20 Hz are "infrasonic" and have too low a frequency to be heard; sounds above 20000 Hz are "ultrasonic" and are too high a frequency to be heard.
