Sound levels above 100 dB can cause hearing loss within minutes. If businesses do not comply with the regulations, they may incur penalties and/or fines.Įxposure to sound levels above 85 decibels (dB) for an extended period of time can cause hearing damage. For instance, in the UK, the permitted noise level at night is 34 dBA if the underlying level of noise is no more than 24 dBA, or 10 dBA above the underlying level of noise if this is more than 24 dBA. A-weighting is the most common, but other weighting systems exist. A-weighting is the standard for determining hearing damage and noise pollution. A-weighting gives more value to frequencies in the middle of human hearing and less value to frequencies at the edges as compared to a flat audio decibel measurement. The A-weighted decibel is the unit that expresses the relative loudness of sounds as perceived by the human ear. 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.
