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 Ares sounds that are to high pitched for the human ear to hear called?
Ultrasound.
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.
What sounds have hertz higher than 20000?
Such sound is called ULTRASOUND. 20,000 Hz (20 kHz) is the approximate upper limit for the human ear.
The lowest frequency a human can hear is?
The sensitivity of the human ear ranges from 20 Hz to 20 kHz. Under ideal conditions in a laboratory, humans have detected sounds as low as 12 Hz.

Is the human ear able to detect?
No
Why mosquitoes make sound near human ear?
Mosquitoes make sounds near the human ear because mosquitoes make sounds everywhere. It sounds as though the mosquitoes are purposely seeking out the human ear when in reality, we only hear them when they're close.
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 Ares sounds that are to high pitched for the human ear to hear called?
Ultrasound.
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
How is the noise of a dog barking measured?
The level of a sound is measured by... a Sound LevelMeter. (!) The reading is in dB(A) which is short for the unwieldy "decibels re 20µPa (A)". A 'decibel' on its own doesn't mean anything outside of its algebra - the abbreviation to just "dB" takes the context as read. The pressure is the scale's reference-level and is that of the faintest sound the healthy human ear can detect. The 'A' is a standard weighting toallow for the human ear's non-linear response to frequency. A text-book or on-line reference on acoustics will explain this further and give typical Sound Pressure Levels relevant to human experience.
How does your ear detect movement?
by the ear drum vibrating
What is the stirrup doing in the human ear?
It's a part of the "transducer" that converts air sounds (large, low pressure) into liquid sounds (low amplitude, high pressure) - it connects the ear drum to the inner ear (a thin section of the skull.
What translates digital audio information from the computer into analog sounds that the human ear can hear?
doodoo
Can a giraffe make sound?
The giraffe makes to little sounds to hear with the human ear
