Which of the following frequencies is infrasonic?
The sound with frequency below 20Hz is called infrasonic wave and the sound with frequency above 20KHz is called ultrasonic wave. Hence, the correct option is (C) 10Hz, since it is less than 20Hz. Note: Humans cannot hear both, ultrasonic and infrasonic waves. However, some animals can sense these waves.
What can hear infrasonic sound?
Some of the animals that are known to hear infrasonic sounds are elephants, rhinoceros and hippopotamus.
What are ultra and infrasonic sound?
Infrasonic Sound has a frequency less than the audible frequency range. Frequencies are less than 20 Hz. The infrasonic sounds have below the lower limit of human hearing. Ultrasonic Sound has a frequency greater than the audible frequency range. Frequencies are more than 20000 Hz.
What is the frequency range of infrasonic and ultrasonic?
Hint: Frequency less than 20Hz is infrasonic, frequency greater than 20,000Hz is ultrasonic, 20Hz to 20,000Hz is audible range for the human ear.
How can you differentiate ultrasonic frequencies from infrasonic frequencies?
An audible sound wave whose frequency is less than 20Hz is in the infrasonic range. The human ear can not hear this sound but elephants and whales can hear this. Ultrasonic sound wave: The frequency above 20,000Hz is in the ultrasonic range.
What is infrasonic sonic and ultrasonic frequencies?
Sounds of frequencies below 20 Hz are called infrasonic sound or infrasound. Frequencies higher than 20 kHz are called ultrasonic sound or ultrasound.
Which is the lower frequency of infrasonic sound?
Lower sounds, in other words frequencies of 2-16 Hz, are called infrasonic. The deeper the frequency, the higher the sound has to be before we can hear it.
Is there such a thing as infrasound sound?
Definitions of infrasound and low-frequency noise are discussed and the fuzzy boundary between them described. Infrasound, in its popular definition as sound below a frequency of 20 Hz, is clearly audible, the hearing threshold having been measured down to 1.5 Hz. The popular concept that sound below 20 Hz is inaudible is not correct.
What is the hearing threshold for infrasound sound?
Infrasound, in its popular definition as sound below a frequency of 20 Hz, is clearly audible, the hearing threshold having been measured down to 1.5 Hz. The popular concept that sound belo … Definitions of infrasound and low-frequency noise are discussed and the fuzzy boundary between them described.
Can a human ear pick up an infrasonic wave?
We cannot hear infrasonic waves, as these frequencies are under that, which the human ear can pick up. Despite this, these sounds can pose a great risk to our hearing and our health. The human ear can pick up sounds from 16-20,000 Hz. Lower sounds, in other words frequencies of 2-16 Hz, are called infrasonic.
