The sounds are too high pitch, plus they send out special vibrations to see what is in front of them in the dark.
The frequencies of sounds that can be heard by most people are between 20 and 20,000 Hz. Sounds outside of this range are possible, but can no longer be heard by humans.
I think what you mean is: What frequencies correspond to sounds heard by humans ?The answer to that one is different for every individual. A representative bandwidth for humansis commonly considered to be 20 Hz to 20,000 Hz.
Audible sound is what is actually heard. Some people will interpret audible sounds differently depending on their ability to hear as well as their perceptions. Animals can "hear" sounds that humans cannot hear. There are ranges of sound that are normal for humans.
Bats do not hear the same as humans. Bats ear are much larger and much more sensitive to sounds due to their lack of eyesight.
20,000 Hertz or simply 20 kHz, is taken to be the upper limit of hearing in younger, healthy humans. Sound frequencies higher than 20 kHz cannot be heard by humans, but can be heard by animals like dogs.
Humans can't hear sounds that are below 20Hz (infrasound) or above 20,000Hz (ultrasound). Infrasound is produced by natural phenomena like earthquakes and by some animals, while ultrasound is used in medical imaging and by animals like bats for echolocation.
Assuming you mean the lowest frequency humans can hear, that's about 20 Hz.
Many species can, including dogs and bats.
Ultrasound
Bowel sounds are best heard at the LUQ
Sounds above 20,000 Hz are considered ultrasonic and are inaudible to humans. Some animals, like bats and whales, can hear sounds in this frequency range. Ultrasonic sounds are commonly used in technology, such as electronic devices like ultrasonic cleaners.
No, high frequencies are heard as high pitched treble sounds.
