If I say: Level of a helicopter = 130 dB, most people are content. Laymen think that a specific decibel value belongs to a noise source. Like heavy truck = 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.
