Scale A denotes when the frequency weighting in the measurement of noise corresponds to frequency response characteristics of the human ear.
Decibel (dB) is a unit in which noise is measured.
Leq is an energy mean of the noise level over a specific period.
There are noise limits that you will have to follow depending on the area you live in. Since measuring noise requires scientific instruments (such as a sound level meter), you may not always know if you are exceeding the noise limits for a particular area. In such cases, you should:
Make sure that regardless of what you do or which equipment you use, it does not turn out to be noisy and a disturbance for others. For example, if you are playing music during a party, try to keep the volume down at night time while people are sleeping.
Don’t wait for your neighbours or people around you to file a complaint to the police. If they mention that you are making noise that is disturbing them, try to reduce the noise.
Please note that it does not matter whether you made the noise unintentionally or intentionally; all that matters is whether you have created too much noise.
