Infrasound refers to frequencies below the audible range of human hearing, typically below 20 Hz. These low-frequency sounds can be produced by natural sources like earthquakes or man-made sources like machinery.

What are sound waves with frequencies above the normal human range of hearing?

Infrasound.


What is the range of frequencies that the human hearing system can detect?

The human hearing system can detect frequencies ranging from about 20 Hz to 20,000 Hz.


Can you hear frequencies beyond the normal range of human hearing?

Yes, some animals can hear frequencies beyond the normal range of human hearing.


What are the differences between ultrasound and infrasound in terms of their frequencies and applications?

Ultrasound and infrasound differ in their frequencies and applications. Ultrasound has frequencies above the range of human hearing, typically above 20,000 Hz, and is used in medical imaging, cleaning, and industrial processes. Infrasound has frequencies below the range of human hearing, typically below 20 Hz, and is used in earthquake detection, monitoring volcanic activity, and studying animal communication.


Frequencies to low for people to hear are called what?

"Subaudible" frequencies.


What is the definition of intrasonic mean?

Intrasonic is the sound frequencies which we can hear.


Which is longer-wavelength of infrasound or ultrasound?

Infrasound has longer wavelengths compared to ultrasound. Infrasound waves have frequencies below the range of human hearing (below 20 Hz), while ultrasound waves have frequencies above the range of human hearing (above 20 kHz), leading to their differences in wavelength.


What is the difference between infra sound and ultrasound?

Infrasound refers to sound waves with frequencies below the range of human hearing (below 20 Hz), while ultrasound refers to sound waves with frequencies above the range of human hearing (above 20 kHz). Infrasound is used in monitoring seismic activity and animal communication, while ultrasound is used in medical imaging, industrial cleaning, and pest control.


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 frequencies can different animals hear?

Dogs have a hearing range of about 40 Hz to 60 kHz, cats can hear frequencies from 45 Hz to 64 kHz, and bats have the widest range of any mammal, up to 110 kHz. Humans typically hear frequencies from about 20 Hz to 20 kHz.
