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 use high-frequency sounds (ultrasound) beyond the range of human hearing to navigate and communicate. These sounds are above 20 kHz, which is generally the upper limit of human hearing.
Bats use echolocation to hear sound. They emit high-frequency sounds, which bounce off objects in the environment and are then detected by the bat's highly sensitive ears. By listening to the echoes that return, bats can navigate and locate prey in the dark.
Dogs can hear sounds with frequencies up to 65,000 vibrations per second, which is higher than what humans can hear. While they may not be able to hear a sound with exactly 75,000 vibrations per second, they have a wider range of hearing than humans.
Depending on age, humans can hear between 20 Hz and 15-20 kHz. Bat calls have a frequency range of 9 kHz to 200 kHz.So Yes.

Bats use sound by sending a sound wave to the object or prey that is going to approch,the sound wave bonces of of the prey and goes back to the bat. The sound wave that goes back to the bat tells the bat how far away the bat is and how fast it is approching the bat.
