Sound waves in the range above 20000 hertz?
Asked in Human Anatomy and Physiology
What is the approximate range of frequencies that humans hear?
Asked in Physics, Electrical Wiring
What frequency of a wave in the air can be heard as an audible sound by the human ear?
Asked in Physics, Science Experiments
What object produce sound when vibrate?
All matter (objects) produce sound when they vibrate with the frequency of audible range. Human ears can hear the sound with frequency range of 20 Hz to 20 kHz (20000 Hertz). So if any object vibrates within the audible range it will produce audible sound. Frequency also denotes the pitch of the sound. If the matter or object vibrates in vacuum, then the sound waves is not heard as it needs a medium for propagation of the waves. The loudness of the sound depends on the Energy in the waves.
Asked in Ultrasounds, The Difference Between
What is the difference between infrasound and ultrasound?
Asked in Domestic Dogs
Why are animals such as dogs able to hear sounds that human cannot?
Asked in Physics
Is echolocation also known as infrasound?
No, infrasound is the frequency of sound that is too low for humans to hear, below 20 hertz, but is used for communicating by elephants and other animals. Echolocation is normally ultrasound, the frequency above our hearing range, higher than 20,000 hertz, and is used by bats and dolphins in echolocation.
Asked in Units of Measure, Physics
Is the frequency of sound measured in units called decibels?
The frequency of sound is measured in Hertz named after Heinrich Rudolf Hertz, the first person to measure electromagnetic waves. A single Hertz represents a single cycle per second. Humans can hear sound from about 40 hertz to nearly 15000 Hertz (also called 15 kilohertz, abbreviated as 15 Khz). Some people with exceptional hearing range may go up to 20 Khz. Some animals can hear even higher frequencies. Decibels are a measurement of how loud a sound is. A decibel is one tenth of a bels named after Alexander Graham Bell;
