Sound and noise are a part of our everyday life. There is no given threshold for when the sound may be perceived as noise. Any sound pressure level will therefore entail a certain probability for nuisance or disturbance.
Noise level is measured in decibels (dB). A normal conversation is about 65 dB, while a shout is about 80 dB. For each increase of 3 dB, the noise effect doubles and 83 dB will therefore have twice as high a sound effect than 80 dB.
Åkerblå conducts sound and noise measurements over shorter and longer periods to map noise levels at the workplace or in other areas.
