13 Albrecht Schneider Arne von Ruschkowski Techno, Decibels, and Politics: an Empirical Study of Modern Dance Music Productions, Sound Pressure Levels, and ‘Loudness Perception’ Summary This paper focuses on possible hearing damage for mainly young people from exposure to excessively loud music in discotheques, clubs, live music venues or by using mp3- players. Current risk evaluating procedures do not take into account a number of factors in an appropriate way, especially when ‘high energy’ music like various styles of techno, trash metal, but even modern pop music, is listened to. In our investigation, we started out with the analysis of several pieces of music from various styles (Techno, Gabber, Pop, Trash Metal, etc.) regarding their level and spectral content. It could be shown that a high overall level combined with reduced dynamics, a high amount of energy in low frequency bands and pulse-like sounds are generally used as stylistic devices in modern popular music. Especially with pulse-like sounds, there is a great risk of hearing damage because high energy levels are reached in a very short time span. In addition, exagge- rated overall levels with reduced dynamics lead to a maximum of energy consumption by the hearing system for most of the listening time. Then, in a second step the tracks were played back over a professional sound system in a club located in Hamburg, recorded via an artificial head and analyzed for their sound pressure level with several common temporal and frequency weightings afterwards. It could be demonstrated that...
