Question

which of the following statements is true in regard to hearing within the animal kingdom?

dogs are the only mammals that can hear sounds humans cannot.
bats are the only mammals that can hear sounds humans cannot.
many nonhuman animals can hear sounds outside of the ranges that humans can hear.
all animals have the same range of hearing ability.

Explanation:

• Dogs and bats are not the only mammals with extended hearing ranges. Many non - human animals, such as dolphins, elephants, etc., can hear sounds outside human hearing ranges.
• It is a well - known fact in biology that different animals have different hearing capabilities. For example, humans typically hear in the range of 20 - 20,000 Hz. Bats can hear ultrasonic sounds (above 20,000 Hz) which are used for echolocation, and elephants can hear infrasonic sounds (below 20 Hz) which are used for long - distance communication.
• The statement that all animals have the same range of hearing ability is incorrect as there is a vast diversity in animal hearing across species.

Answer:

Many nonhuman animals can hear sounds outside of the ranges that humans can hear.
