Noise in domestic and work environments is usually measured based on noise power. This is not reflecting the fact that temporal and spectral structure of the noise, but also the activity of the test subject influences the annoyance. In addition there is a difference between artificial noise signals and noise signals that probably have a meaning to the listener. In this study 15 assessors evaluated the perception of 23 natural noise stimuli at four different levels in two different situations. The situations are spatial recordings of a library and a canteen. The test subjects are not focusing on listening but on tasks but told to indicate when noise is distorting their activities.
