Sound is vibration. Sounds are produced by vibrating objects. For example, pond water gurgles, the wind in the trees, and the sound of dogs barking.
So, sound is vibration. However, not all vibrations can produce sound. There are some objects that are vibrating, but the sound cannot be heard. If the number of vibrations of an object per unit of time does not meet a certain number, the resulting sound cannot be heard.
Sounds that can be heard by normal human ears have a frequency between 20 vibrations per second (hertz = Hz) to 20,000 vibrations per second (hertz = Hz). Sounds in this frequency range are called audiosonics.
Sounds whose frequency is less than 20 Hz cannot be heard by normal human ears. Sounds in this frequency area are called infrasound. Likewise, sounds with frequencies above 20,000 Hz. The sound in this frequency area is called … Read More
