Spectral balance (the relation between high and low frequencies) is an auditory metric thatcorrelates with annoyance. However, previous research has shown conflicting results whereincreased annoyance has been linked to both increased high frequency content [1] and lowfrequency content [2]. The aim of this research is to test the hypothesis that the informationcontent of the signal could be a contributing factor to this discrepancy. An experiment wasperformed where participants rated sounds with different spectral slopes (flat, 3.5 dB/oct, 5.5dB/oct and 7.5 dB/oct) and different information content (varying from original recording of atruck sound to a noise spectrum). The results showed that different spectral slopes werepreferred for different levels of information content.
