Abstract
In the measurement of noise stress and noise nuisance the use of the A value of the sound pressure level has become worldwide. The main reason for this acceptance is that the frequency weighting of the A-curve is a close approximation to the frequency dependence of damage to hearing. However this does not help in the estimation of loudness. Moreover at higher sound levels considerable errors are in volved in calculation if the A-level value is used. For the criterion of noise stress it is more the loudness level or the (incalculable) loudness which provides the correct limiting point. It appears to be at the point in time at which the current magnitudes in hearing (also for the fluctuating level), i. e. phon or sone, can be measurement sufficiently approximate and with justifiable expenditure. The assumptions for this are discussed.
