It will log these measurements and use them to decide if a business is being excessively noisy. In the UK, members of the public can report noise from business premises (garages, workshops using power tools, bars and restaurants playing music, etc.) to their local council, which may then use a sound level meter to measure the sound at different times of the day or night. The noise limit also depends on the legislation in force in each country. From 120 decibels: exposure causes pain.Nevertheless, organisations such as the WHO have set limits to prevent the risks of noise to health. In general, several factors are involved in determining the maximum safe sound level: the frequency and duration of the sound, its intensity and so on. What are the adverse health effects of noise? What is the noise limit that should not be exceeded? In the same way, a sound higher than 2,000 Hz is not perceptible: it is an ultrasound. 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.
