We can hear sounds because our ears turn sound ... Dogs ears can detect the sound, humans can’t because the frequency is above 20 kHz. In 2005, Howard Stapleton from Barry in South Wales ...

Humans can’t naturally produce sounds in the ultrasonic frequency range. Nor could we hear them if we did. That doesn’t mean we can’t echolocate, though—it just means we don’t have quite ...

Humans can hear sounds that have a frequency of between 20Hz (hertz) to 20kHz (kilohertz). The scientists recorded the frogs as they were screaming with a high-frequency audio recorder which ...

This is an audio recording of plant sounds. The frequency was lowered so that it is audible to human ears.

Bats, whales, rhinos, dogs, pigeons, cuttlefish… all sorts of animals use infrasonic and ultrasonic frequencies to communicate, and humans can hear none of it. So the next time you're enjoying a ...

A higher sound frequency results in a higher pitch or sharpness. Frequency is denoted by Hertz (Hz). Human beings can hear a different range of sound frequencies. The human audible range is 20 Hz ...
