If the sound pressure is less than 20 hertz (Hz) then the sound produced is not audible to the human ear. It should also be noted that our eardrums are not receptive to all vibrations. So it's an unpleasant sound that can even be dangerous to health and even cause hearing loss depending on its intensity and frequency. However, what characterises noise is the discomfort it causes when perceived. Sound and noise are the same thing: vibrations in the air that are perceived by our ears, more precisely our eardrums, and then transmitted to our brain. How is noise defined? What’s the difference between a noise and a sound? It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale and is named after its inventor Alexander Graham Bell. its intensity (from the lowest intensity to the highest intensity).The decibel is a relative unit of measurement equal to one tenth of a bel. This tool uses the decibel (dB) as its unit of measurement to rate noise according to its sound pressure, i.e. The decibel scale is a relative unit of measurement that's used to measure the amount of sound in a given environment.
