Sounds with a lower frequency than 20 Hz are infrasound, which include natural occurrences like earthquakes and some animal calls. These low-frequency sounds are typically felt more than heard.

Introduction of ultrasonic?

we know that human ear can not hear sounds of frequency less than 20Hz or more than about 20,000 Hz . Sounds of frequency higher than 20,000 Hz , which are inaudible to human ear, can be produced and are utilized in many useful ways. Such sounds are called ultrasonics


What are two animals that can hear lower frequency sounds than a human?

Both whales and elephants can hear extremely low frequency sounds.


What is the difference between the higher and lower pitch?

Pitch refers to how high or low a sound is. Higher pitch sounds have a faster frequency of vibration, creating a sound that is perceived as higher in frequency than lower pitch sounds. Pitch is determined by the frequency of the sound wave - higher pitch sounds have higher frequencies while lower pitch sounds have lower frequencies.


Does a lower pitch song have a higher frequency than a high pitch sound?

No, lower pitch sounds have lower frequencies and higher pitch sounds have higher frequencies. Frequency refers to the number of oscillations per unit of time, so a lower pitch sound will have a lower frequency and vice versa.


Can you hear high pitched or lower pitched sounds better underwater?

Higher pitched sounds are typically easier to hear underwater compared to lower pitched sounds. The reason for this is that water is a denser medium than air, which results in faster attenuation of lower frequency sounds and better transmission of higher frequency sounds.


Do high frequency sounds affect animals?

It depends on the type of animal. Dogs can hear a higher frequency than humans, which is the concept behind a dog whistle. Elephants can hear lower sounds than humans.


What are the below audible frequency sounds?

Below audible frequencies are sounds that are too low for the human ear to detect. These frequencies are typically below 20 Hz and are often felt as vibrations rather than heard as distinct sounds. Some animals, like elephants and whales, can detect and communicate using infrasound frequencies.


Meaning of high sounds?

High frequency (high pitch) sounds have a higher frequency than those of lower pitch. The air molecules of a high frequency sound, vibrate back and forth much more frequently.


Can you hear a wind blowing at 15Hz?

No, the human ear cannot detect sounds at 15Hz. The audible range for most people is typically between 20Hz to 20,000Hz. Frequencies below 20Hz are felt as vibrations rather than heard as distinct sounds.


In your voice if amplitude coresponds to loudness means then what frequency corresponds?

Frequency corresponds to the 'pitch' of the voice. The sounds in a little girl's voice have higher frequencies than the sounds in an adult man's voice. And the sound of a whistle has a higher frequency than the sound of a tuba or foghorn.


What is the lowest frequency a human can ear?

20Hz


Do high frequency sound waves have a higher or lower pitch than low frequency sound wave?

Yes! All sound waves, regardless of pitch move at the same speed provided they are in the same medium. Differences in frequency cause the sound to be perceived as higher or lower. A high pitched sound has a higher frequency and shorter wavelength while low pitched sounds have lower frequencies and longer wavelengths
