If the high frequency sound is within hearing range, you can hear it as a high-pitched sound. If it's out of the hearing range you can't hear it, of course.
Sound too low in frequency to hear (~<20Hz) is called infrasound. Sound too high infrequency to hear (~>20kHz) is called ultrasound.
the sound that is too high pitch to hear is called an ultrasound.
The term for any sound that is too high for humans to hear is "ultrasonic."
Sound waves that are too low to hear are referred to as infrasound. These waves have frequencies below the threshold of human hearing, typically below 20 Hz. Even though we cannot hear them, infrasound waves can still have effects on humans and animals.
Sound with a frequency lower than about 20 cycles per second, called infrasonic sound. Sound with a frequency higher than about 20,000 cycles per second, called ultrasonic sound. Only those with excellent hearing can perceive sound at these extremes. As we age and as our hearing is damaged by exposure to loud sounds, the frequency range of hearing is reduced. Some animals can hear sounds above and below the range of humans.
Sound waves too high for humans to hear are called: ultrasonic
The human ear can hear sounds up to a frequency of about 20,000 Hertz.
Bats use echolocation to sense movement and their surroundings. We cannot hear the high pitched noise they emit because it is of a higher frequency than the human ear can register. There are some sounds of a bat that we can hear, but the sounds that we can't hear is because the squeaks are so high that you really need ultrasound to hear it.
Bats. They are blind and use echolocation to navigate when they are flying. They emit high pitched sounds humans ears are unable to hear. The sound frequency in a human voice is too low pitched for them to hear.
