Note that, for ordinary sounds, the intensity value is usually very small.X Research source Because of this direct relationship between a sound wave intensity and its volume in decibels, it's possible to find a decibel value given nothing more than an intensity level for the sound (which is typically measured in watts/square meter) The larger the amplitude of a given sound wave, the more energy it transmits, the more it moves the air particles in its path, and the more 'intense' the sound is. In physics, decibels are often thought of as a convenient way of expressing the intensity of a sound wave. However, the truth is a little more complex.

For everyday practical purposes, decibels are usually seen as a simple measure of loudness. Immediate hearing loss or eardrum rupture possibleįind your sound's intensity in watts/square meter. May be immediately painful damage after lengthy exposure very likely
