Humans

• Humans have a range of 64-23000hz

An audiogram showing typical slight hearing variation.

There is a difference in sensitivity of hearing between the sexes, with women typically having a higher sensitivity to higher frequencies than men.

Bats

• A bats hearing range is 2000-110000

.Bats require very sensitive hearing to compensate for their lack of visual stimuli, particularly in a hunting situation, and for navigation.

The type of insect and how big it is can be determined by the quality of the echo and time it takes for the echo to rebound; there are two types; constant frequency and frequency maculated calls that descend in pitch.

Dogs

• A dogs hearing range is 67-45000hz

The hearing ability of a dog is dependent on its breed and age.

Sounds that seem loud to humans often emit high frequency tones that can scare away dogs and ultrasonic signals are used in training whistles as a dog will respond much better to such levels. In the wild, dogs use their hearing capabilities to hunt and locate food. Domestic breeds are often used as guard dogs due to their increased hearing ability
