The exact frequency limits of human sound perception vary from one individual person to the next, but as a population average, the audio industry has always used the range of 20 Hz to 20,000 Hz.

What are sounds with frequencies below 20 hertz called?
Infrasonic.'Subsonic' and 'infrasonic' both define sound too low (in frequency or pitch) to be heard by humans without assistance.However, as 'subsonic' can also mean something traveling slower than the speed of sound, and 'infrasonic' only means frequencies below the audible range, 'infrasonic' is the better answer.
What is the longest wavelength that can be heard by a normal ear?
The lower frequency limit of human hearing is generally considered to be around 20 Hz.At a speed of sound of 340 meters/sec, that frequency corresponds to a wavelength of(340/20) = 17 meters, in air.
What is different between infrasound and ultrasound?
Infrasound is sound that is lower in frequency than 20 Hz (Hertz) or cycles per second, the normal limit of human hearing. Ultrasonic waves have frequencies above the audible range at around 20 kHz. Audible sound is within human hearing range.
What are infrasound waves?
Just like "infrared" is light that we can't see because its frequency is lower than the frequency of red light, "infrasound" is vibration or waves in air that we don't hear, because its frequency is lower that the lower limit of human sound perception.
What are the Sources of infrasonic sound?
Infrasonic sound below the range of human hearing at 20 cycles per second, can include severe weather, surf, avalanches, earthquakes, volcanoes, waterfalls, calving of icebergs, meteors, and thunder. You can often 'feel' infrasound, especially in your chest.

When do you have an ultra sound?
Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing. This frequency varies from person to person, it is approximately 20 kilohertz (20,000 hertz). This is the lower limit in describing ultrasound.
Sounds that are below the range of human hearing?
The sounds with frequency below the hearing range are named Infrasounds and the sounds with frequency above the hearing range are named Ultrasounds. I would say infrasonic . 20000

What are two animals that can hear lower frequency sounds than a human?
Both whales and elephants can hear extremely low frequency sounds.
Can humans hear the sonic range?
The Human hearing range IS the sonic range. Sounds which fall under the ultrasonic range are sounds which emit a higher frequency then we can hear (ie. dogs hear within this range). Infrasonic sounds emit lower frequencies then we can hear. The human hearing range or 'Sonic' range is between 16- 20 000 Hz, though changes with age
What is the relation between pitch and frequency?
the lower the frequency the lower the pitch; higher pitch lower frequency

What name is given to the sounds which a cat can hear but a human cannot?
Sound with a frequency lower than about 20 cycles per second, called infrasonic sound. Sound with a frequency higher than about 20,000 cycles per second, called ultrasonic sound. Only those with excellent hearing can perceive sound at these extremes. As we age and as our hearing is damaged by exposure to loud sounds, the frequency range of hearing is reduced. Some animals can hear sounds above and below the range of humans.
