    Laboratory experiments have shown that airborne and impact noise from neighbours are evaluated in approximately the same way. For both types of noise was found that the interval between 20% and 80% annoyed corresponded to a level difference of 16 dB. 50% of the subjects felt annoyed by the noise at an A-weighted level of 27-28 dB. The results from a number of field investigations lead to the conclusion that in order to meet the users' demands for acoustic quality in dwellings, the airborne sound insulation between flats in new buildings should fulfil 60 dB and the impact sound pressure level should fulfil 48 dB, preferably evasluated in an extended frequency range down to 50 Hz. It can be assumed that this level of sound insulation will be characterized as 'satisfactory' by most people, and only a very limited number of complaints can be foreseen.
