One idea is that the creatures lost some of their hearing ability because the sense isnt required underground. The upper limit for a pigeon is as high as 10kHz. As a rule, birds are most sensitive to sounds in the range between 1-4 kHz. Should work for the op though, since its just looking for something comparable to blind as a bat after all. Deaf as a _____? They do not hear the lower frequencies that we can; they communicate using high frequency noises some of which are inaudible by humans. They can pull 1,141 times their own body weight. Killer whales and their relatives specialize in detecting ultrasounds at high frequencies.

This helps them to better determine which direction a sound is coming from when it reaches their ears. Fortunately, their internal ears are developed, which allows them to listen. Echolocation is a process of emitting ultrasonic squeaks whilst in flight, then measuring the time it takes the sound vibration to hit a nearby surface and bounce back. Unless its a deaf snake. Some animals with bad hearing can use echolocation, which means that the animal makes a noise and listens for how it echoes back to find prey or recognize danger.

This confirmed that they struggled to hear quiet sounds and could only perceive sound between a narrow frequency, between 0.5 and 4 kiloHertz. This means that sharks use electricity around their preys muscles to detect animals with this technique. Labradors are often used as hearing dogs for deaf individuals and do It uses echolocation, emitting ultrasonic sounds and measuring the length of time before the sounds echo back, in order to locate prey.
