This paper presents an overview of the following exposure-response relationships that can be used for assessing the impact of environmental noise: • Lden - annoyance relationships from the EU Position Paper on exposure-response relationships for transportation noise annoyance (EC-WG/2 2002; Env. Health Persp. 2001, 109 (4) 409-416). In addition, factors other than Lden which influence noise annoyance are discussed; •L den - annoyance relationships for stationary (industrial) sources (J. Acoust. Soc. Am. 2004, 116 (1) 334-343). A distinction is made between different types of stationary sources; • Lden - annoyance relationships for combined sources (J. Acoust. Soc. Am. 2004, 116 (2) 949- 957); • Lnight - self-reported sleep disturbance relationships from the EU Position Paper on exposure-response relationships for sleep disturbance (EC-WG/HSEA, 2004; Beh. Sleep Med. 2007, 5 (1) 1-20). In order to put self-reported sleep disturbance in a context, a brief overview of other noise-induced effects on sleep is given; • Lden - myocardial infarction relationships (Umweltbundesamt 2006, report WaBoLu 01-06). Furthermore, recent developments and insights related to the above relationships are discussed.
