Heterodyning - mixing the sound from the bat with a steady ultrasonic frequency of similar frequency. They do not chew on woodwork so you will not hear any grinding noises, but you may hear a high pitched cricket noises. The shorter wavelengths of ultrasonic sounds make them more likely to bounce back to the bat, rather than diffract, or bend around, objects. When noise interferes, the bats cannot do these things. I have two cats, one is a hunter and one is a dunce. However, elephants can hear waves as low as 14 hz, while cats can hear up to 64,000 hz frequencies, and bats can sometimes pick up noises as high as 200,000 hz. Different types of bats hear in different ways. Bats are generally very quiet, but they often do make a soft scratching noise as they crawl around. Human ears can hear noises ranging from 20 Hz to 20,000 Hz. Ultrasonic Sounds. Ultrasonic sounds require less energy to produce.

Do not use naphthalene flakes or mothballs, which contain chemicals that can be toxic to humans and other life forms; poisoned bats may fall to the ground where they die slowly and are more likely to come into contact with children or pets. A bat sees without its eyes but instead uses the images produced by its brain; it uses the echo it receives back after making an echolocation call. When the flying mammals use echolocation, humans are only sometimes able to make out very quiet clicks. Bats make a variety of sounds that can be broken into the two categories of echo location sounds and communication sounds.

Most of the times during the night fox squirrels and grey squirrels are sleeping and there is very little noise. Humans can hear sounds from about 20 to 20,000 Hz. The frequency-modulated components themselves can be narrowband (consisting of a small range of frequencies) or broadband (composed of a wide range of frequencies). A human’s hearing is maxed out at 20 kilohertz, but you can still hear some form of echolocation clicks from specific bat species.
