What animals can hear ultrasound and infrasound?

What animals can hear ultrasound and infrasound?

Certain animals can emit and hear ultra-sonic frequencies more than 20 kilohertz. Bats, Insects like beetles, moths, praying mantis, dolphins, dogs, frogs and toads, etc. communicate using ultrasonic hearing. Infrasound, is a low-frequency sound less than 20Hz.

Which animal can hear ultrasonic sound?

Ultrasonic sound waves are the waves having frequency above 20,000 hertz. Animals such as bats, dos and dolphins can hear these high pitched sounds. So, the correct answer to this question is dogs, bats and dolphins.

Do all animals use ultrasound and infrasound?

Animals use songs and sounds to communicate. Some of these sounds are produced within human auditory ranges, which for most of us is between 20 and 20,000 vibrations per second. (20 HZ-20kHZ) Sound that is lower than 20 vibrations is called infrasound. Bats use ultrasound to communicate and find insects to eat.

What are audible infrasonic and ultrasonic sounds?

Audible sound waves whose frequencies are less than 20 Hz are in the infrasonic range. Frequencies above 20,000 Hz are in the ultrasonic range. The audible range of dogs, cats, moths and mice extends into ultrasound frequencies. They can hear very high frequencies that humans cannot.

Can hear ultrasonic sound?

An ultrasound is not a unique type of sound, therefore, but is classified differently due to the fact that humans cannot hear it. Ultrasounds have a frequency greater than 20 kHz, which is beyond the frequency limit of sounds that humans are able to hear.

What are infrasonic and ultrasonic?

The sounds of frequency less than 20Hz are called infrasonics. The infrasonicsounds have below the lower limit of human hearing. The sound of frequency more than 20,000Hz are called ultrasonics. ultrasonic sounds have a frequency above the upper limit of human hearing.

What animals can detect ultrasound?


  • Ultrasound is sound that has a wave frequency higher than the human ear can detect.
  • Animals such as bats and dolphins send out ultrasound waves and use their echoes to identify the locations of objects they cannot see.
  • Sonar stands for sound navigation and ranging.

Do ultrasonic sounds harm humans?

Ultrasound at sufficient sound pressure levels can cause hearing damage even if it cannot be heard. Even a device designed to be safe for humans may cause nuisance or harm to pets and other animals due to their extended range of hearing. Many ultrasound devices emit airborne ultrasound.

What is an example of infrasonic?

What is Infrasound? For example, some animals, such as whales, elephants and giraffes communicate using infrasound over long distances. Avalanches, volcanoes, earthquakes, ocean waves, water falls and meteors generate infrasonic waves.

Why is infrasonic sound useful for scientists?

Scientists use infrasound to detect earthquakes and volcanic eruptions, to map rock and petroleum formations underground, and to study activity in the human heart.

Are ultrasonic frequencies harmful to humans?

audible frequencies may cause annoyance, tinni- tus, headache, fatigue and nausea and (b) ultra- sound components with high sound pressure level may cause hearing damage.
