Noise Pollution
Event organizers should remember that noise is pollution too. Not all sound is noise, but the World Health Organization WHO defines the noise limit as 65 decibels.
Usually the maximum decibel limit for outdoor events is around 90–100 dB, for indoor events it is slightly lower – but even prolonged exposure to 85dB can damage the hearing. As a rule, using audio equipment in outdoor events is only allowed from 9 am to 10 pm, so if you want to play music outside this time window, it is recommendable that you also consider the indoor option.
The sound from PA System is temporary noise, meaning it must be notified to the local environmental protection official. Read more on the City of Oulu Environmental Control website.
Do this
Beginners
If your event is organized outdoors, take the nearby nature and neighbors into consideration.
Inform local residents about the noise caused by your event.
Distribute or sell earplugs to the audience, and organize hearing protectors for the staff.
Advanced
Place performing stages and sound systems in such a way that they cause as little harm as possible to the surrounding neighborhood and that the noise does not travel through waterways to residential houses.
Take into consideration that noise pollution in nature sites can disturb animals too.
Next Level
Do not shoot fireworks, which cause noise that causes excess stress and fear in pets and birds.
