There are two transducers (the ear drum and a thin section of skull) where sound is shifted from one media to another (air 2 mechanical & mechanical to liquid),
and a transducer in between to change high amplitude, low power into low amplitude, high power.
Each one of these is a mechanical device with its own resonant frequencies and moments of inertia.

What main regioin of the human ear contains the ear canal?
Outer ear
What main region of the human ear contains the ear canal?
External ear contains ear canal.
Does sound velocity change based upon sound frequency?
Speed of sound is not frequency dependent. Speed of sound is dependent only on the temperature. At 20°C the speed of sound is 343 m/s.
What are facts about the human ear?
the middle ear is the smallest bone in the body
How is the pressure variation in a sound wave amplified in human ear?
how is the pressure varition in a sound wave amplified in human ear
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 is the properties of ultrasonic sound waves?
They have a frequency of above 20,000Hz inaudible to human ear.
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 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?
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.
What frequency of a wave 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.
Is The frequency of the lowest sound that the normal human ear can perceive ranges between 16 and 20 Hertz?
no
Introduction of ultrasonic?
we know that human ear can not hear sounds of frequency less than 20Hz or more than about 20,000 Hz . Sounds of frequency higher than 20,000 Hz , which are inaudible to human ear, can be produced and are utilized in many useful ways. Such sounds are called ultrasonics
