a bat
bat
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.
A word that sounds the same and is spelled the same is called a homonym. An example of a homonym is "bat," which can refer to either the flying mammal or the piece of sports equipment.
Rabbit
whale, dolphin
Whales navigate with subsonic vibrations. like sonar
Homonyms are words that have the same pronunciation or spelling but different meanings. They can cause confusion in communication. Examples include "bat" (flying mammal) and "bat" (sports equipment).
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.
Since dogs can hear high pitched sounds humans cannot hear, it is more likely a dog becomes frightened or upset from something the dog hears that you cannot hear.
No. The seal is an ocean animal, and it is a mammal.
The human ear cannot detect all possible frequencies. It has evolved to detect frequencies of sounds that are the most useful to humans, and has a maximum frequency range of about 20Hz to 20kHz, which decreases as you get older, particularly at the higher end. Infrasonic describes sounds that are too low in frequency to be heard by the human ear, and ultrasonic describes sounds that are too high in frequency to be heard by the human ear. These sounds cannot be heard by the human ear because they are outside of its range of capability.
They hear sounds in the same way that humans do.
