  1. Wind Turbine noise: Characteristics of Strongly Annoyed Residents Johannes Pohl & Gundula Hübner Institute of Psychology Health and Environmental Psychology Martin-Luther-University Halle-Wittenberg and MSHMedicalSchoolHamburg Germany 30.05.2018, Stockholm

  2. Situation • regulations for maximal SPL of WT noise • residents complains • need for deeper problem analysis • need for guidelines for problematic cases

  3. Diagnostic tools • questionnaire, face-to-face interview • complain sheet • app, noise indicator • audio recorder • long-term noise monitoring • background information concerning the planning process (e.g., support, opposition, conflicts)

  4. Annoyance induced by WT immissions

  5. Definition for strong WT annoyance (Pohl et al., 2018) • at least somewhat annoyed + psychological or somatic symptoms occuring at least once a month • 9.9 % of the participants in 2012 and 6.8 % in 2014 were strongly annoyed by WT noise but 16 % by traffic noise

  6. Strongly annoyed residents a In the representative U.S. study weighted percentages are used (Hübner et al., 2018). In the combined three European studies they are the actual percentages (Hübner & Löffler, 2013; Pohl et al., 2012, 2018).

  7. Symptoms attributed to WT noise (Pohl et al., 2018) • hindered falling asleep 7 %, multiple awakening 5 % • reduced performance 5 %, reduced attention 5 % • tiredness 5 % • nervousness 4 %, tenseness 5 % • negative mood 7 %, helplessness 4 % • irritation, anger, hostility 6 % • feeling of pressure related to WT sound waves 9 % • body vibrations related to WT sound waves 6 %

  8. Typical WT noise situation (Pohl et al., 2018) • frequency: about once a week 60 % • time of day: evening or night 52 % • noise descriptors: swoosh 77 %, boom 73 % • disturbed activities: sleeping 30 %, relaxing 25 %, leisure activities 22 % • immediate noise reactions: irritated, angry 32 % • wind: down wind 69 %, 6-9 m/s at hub height • amplitude modulation

  9. Behavioural coping (Pohl et al., 2018) • window closing 26 % • place leaving outside 12 % • place leaving inside 7 % • radio / TV volume up 8 % • conversation with relatives 32 %

  10. Cognitive coping (Pohl et al., 2018)

  11. Personal features (Pohl et al., 2018) • 75 % of participants with symptoms in comparison to 34 % without symptoms were passive or active against the wind farm in the past • greater strain during planning / construction phase • greater noise sensitivity

  12. Correlations with WT sound annoyance

  13. Psychological factors • positive expectations (e.g., financial participation) • negative expectations (nocebo effect) • justice, fairness • preload • intensified self-observation • misattribution vs. explanations • visibility • negative attitude, opposition

  14. Conclusion • significant acoustical factors • significant psychological factors • noise and impact mitigation • taken residents concerns seriously • early and informal resident participation • fair planning process

  15. Ongoing research on WT noise in Germany • low frequency noise (laboratory study) • amplitude modulation (field study) • TremAc: Objective Criteria for Seismic and Acoustic Emission of Inland Wind Turbines (modelling, field studies)
