Mention three types of sound frequencies and explain them!
Here are three types of sound frequencies:
- Ultrasonic
- Audiosonics
- Infrasound
The explanation is as follows:
- Ultrasonics are sounds with frequencies above 20,000 Hz, this type of ultrasonic sound can be picked up by bats and dolphins.
- Audio sound is a type of sound whose frequency is between 20 HZ – 20,000 Hz and can be perceived by humans.
- Infrasound is a sound whose frequency is less than 20 Hz, infrasonic sounds can be picked up by crickets and elephants.
