Human beings can normally hear sounds with a frequency between about 20 Hz and 20,000 Hz. Sounds with frequencies below 20 hertz are called infrasound. Infrasound is too low-pitched for humans to hear.
Read moreWhat does 7 Hz do to the body?
Especially dangerous is infrasound at the frequency of 7 Hz, since this sound, generating frequencies, close to characteristic frequencies of the organs of our body, may disturb the heart or brain activity . Machines, natural sources storms, earthquakes, hurricanes, etc. generate infrasound.
Read moreWhat is the lowest frequency humans can make?
Human ear perceives frequencies between 20 Hz (lowest pitch) to 20 kHz (highest pitch). All sounds below 20 Hz are qualified as infrasounds, althought some animals (ex. mole-rat, or elephant) are hearing them.
Read moreHow do you determine low and high frequency?
The number of waves that pass a fixed point in a given amount of time is wave frequency. Wave frequency can be measured by counting the number of crests (high points) of waves that pass the fixed point in 1 second or some other time period . The higher the number is, the greater the frequency of the waves.
Read moreWhat is the main difference between low and high frequency waves?
The frequency of a wave is inversely proportional to its wavelength . That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength.
