Normal human hearing range is 20-20,000 Hz. SONAR A device that uses sound waves to determine water depth Threshold. The point where humans begin to detect and hear sounds. Ultrasonic Sounds with a frequency above 20,000 hertz, that can not be heard by humans. Some animals, such as dogs, can hear ultrasonic sounds, like dog whistles.

Beyond normal hearing for humans, although some animals (like dogs) hear part ways into this range. Also used in medicine (e.g. ultrasounds) Speed of Sound. The speed of sound in air actually depends on the temperature of the air. At zero degrees the speed of sound through air has been experimentally found to be 331.4 m/s and this value ...

Through the sense of hearing we are placed into direct, intimate contact with the surrounding world. Musical, vocal, and other sonic impressions flood us constantly. The normal human ear is sensitive to sonic frequencies ranging from about 20 to 20,000 Hertz (1 Hz = 1 cycle/second), although the range varies with age and other individual factors.
