WebWhales, dolphins, and porpoises communicate using high-pitched sounds that travel through the water. The speed at which sound travels depends on many factors, one of which is the depth of the water. At approximately 1,000 meters below sea level, the speed of sound is 1,480 meters per second. The speed of sound increases at a constant rate of 0. ...

WebJun 16, 2024 · On the one hand, there is of course the pump noise, but even in 'high flow' configurations (i.e. where the pump is operated at high speed) the pump usually operates relatively silent. WebHigh frequencies produce more oscillations. The units of frequency are called hertz (Hz). Humans with normal hearing can hear sounds between 20 Hz and 20,000 Hz. Frequencies above 20,000 Hz are known as ultrasound. When your dog tilts his head to listen to seemingly imaginary sounds, he is tuning in to ultrasonic frequencies, as high as 45,000 Hz.
