The typical hearing range for a healthy young person is from 20-20,000 Hz, allowing them to hear low and high pitched sounds. As we age, the ability to hear higher frequencies lessens. Many animals like dogs and bats can hear a much broader frequency range than humans, from 40 Hz - 60,000 Hz for dogs and 20 Hz - 120,000 Hz for bats, which helps them locate sounds and prey. While a human's hearing range is not as broad as other animals, nature has evolved our senses to an optimal level for our environment.
