If I say jetplane = 130 dB, most people are content.Laymen think that a specific decibel value belongs to a noise source. Like helicopter = 100 dB, jackhammer = 110 dB, rock band 120 dB. That is not correct.Alway is forgotten that the distance from the sound source to the measuring point plays an important role. Sound level decreases by (−)6 dB per doubling of distance from the source. Without any distance a dB value is really nonsense.
