  2. Expert Panel on Noise (EPoN)

  3. European Environmental Agency (EEA)Expert Panel on Noise (EPoN)Priority Tasks • Working group that aims to support the European Environmental Agency and the European Commission with the implementation and development of an effective noise policy for Europe. • Assist with the development of the European Noise Database and specifically advise on the linkages between population exposure and potential health effects. • Assist EEA and the DG ENV with the drafting of guidelines on the preparation of noise action plans including cost benefit analyses.

  4. EU Noise PolicyCALM Network Coordination of European Research for Advanced Transport Noise Mitigation, funded by the 6th Framework Programme of the European Community “Avoid harmful effects of noise exposure from all sources and preserve quiet areas.” Community Research Strategy Plan Source: CALM (2004)

  5. Environmental Noise Directive (END)Directive 2002/49/EG • Environmental Noise Directive (END) (2002/49/EC 2002) • "…assessment and management of environmental noise action plans to reduce harmful effects of noise exposure." Annex III: “... dose-effect curves should be used to assess the effects of noise on populations.” Source: CALM (2004)

  9. Sound  Noise • Noise is normally defined as "unwanted sound". • Noise is "audible sound that causes disturbance, impairment or health damage".

  10. Sound  Noise • Noise is normally defined as "unwanted sound". • Noise is audible sound that causes disturbance, impairment or health damage. • The terms "noise" and "sound" are often synonymously used when the purely acoustical dimension is meant (e. g. noise level, noise indicator, noise regulation, noise limit, noise standard, noise action plan, aircraft noise, road traffic noise, occupational noise).

  11. Sound  Noise • Noise is normally defined as "unwanted sound". • Noise is audible sound that causes disturbance, impairment or health damage. • The terms "noise" and "sound" are often synonymously used when the purely acoustical dimension is meant (e. g. noise level, noise indicator, noise regulation, noise limit, noise standard, noise action plan, aircraft noise, road traffic noise, occupational noise). • The link between exposure and outcome is given by reasonably well-established exposure-response curves which are derived from research into noise effects.

  18. Health Endpoints Annoyance Noise annoyance is a term used in generalfor all negative feelings such as disturbance, dissatisfaction, displeasure, irritation and nuisance.

  19. ICBEN ScaleISO 15666 1)"Thinking about the last 12 months or so, when you are here at home, how much does noise from (...source...) bother, disturb, or annoy you?" Extremely – Very – Moderately – Slightly – Not at all 2) "Next is a zero to ten option scale for how much (...source...) noise bothers, disturbs or annoys you when you are here at home. If you are not at all annoyed choose zero, if you are extremely annoyed choose ten, if you are somewhat in between choose a number between zero and ten." "Thinking about the last 12 months or so, what number from zero to ten best shows how much you are bothered, disturbed, or annoyed by (...source...) noise?" 0 – 1 – 2 – 3 – 4 – 5 – 6 – 7 – 8 – 9 – 10 Not at all Extremely Severely annoyed

  20. ICBEN ScaleCut-off Points 1) "Highly annoyed": 72% of the scale length 2) "Annoyed": 50% of the scale length 3) "Little annoyed": 18% of the scale length 4) Continuous scale

Altogether, 10 million 8-hour nights with 1 to 200 (1, 2, 3,…, 200) noise events randomly drawn from the DLR field study 20 were simulated. The lines represent (from below to above) 2.5, 25, 50, 75, and 97.5 percentiles. In an 8 h undisturbed night of a healthy sleeper, on average 24 spontaneous EEG awakenings (as defined by Rechtschaffen and Kales1) can be observed (equalling 8,760 spontaneous awakenings per year).

  40. Hypothetical Exposure-Response Curve- Cognitively Affected - Staffan Hygge Assuming that 100% of the noise exposed are cognitively affected at a very high noise level, e.g. 95 Ldn, and that none are affected at a safely low level, e.g. 50 Ldn, a straight line (linear accumulation) connecting these two points, as in the Figure below can be used as basis for approximation. Since for theoretical reasons based on an (assumed) underlying normal distribution, the true curve should have the same sigmoidal function form as the two curves in the figure.

  42. Attributable FractionFormula Population attributable risk Impact fraction AF = {(Pi * RRi) - 1} /  (Pi * RRi) where: Pi = Proportion of the population in exposure category iRRi = relative risk at exposure category i compared to the reference level

  43. Attributable Fraction: Myocardial Infarction / IHDExample: Germany, Adults Moyocardial Infarction (MI) Caused By Traffic Noise Reference year 1999 Attributable fraction: 2.9% Germany 1999: MI: 133,115 cases IHD: 849,557 cases Due to road traffic noise: 3,900 MI cases/year 24,700 IHD cases/year MI = Myocardial infarctionIHD = Ischaemic heart diseases * Probabilistic model

  44. DALYsDisability Adjusted Life Years • Idea: One figure to aggregate different levels of severityQuantification unit, priority setting, DALYs as a public health currency • DALY = YLL + YLDThe sum of years of potential life lost due to prematuremortality and the years of productive life lost due to disabilityYLL = ND (number of deaths) x DW (disability weight) x LD (standard life expectancy at age of death in years)YLD = NI (number of incident cases) x DW (disability weight) x LI (average duration of disability in years) • Severity weight factors (disability weights)Dependent on cultural weighing systems, expert rating

  45. Disability WeightsDALYs Disability weights that have been used • Mortality = 1.000 • Non-fatal acute myocardial infarction = 0.406 (WHO) • Ischaemic heart disease = 0.350 (de Hollander, 1999) • High blood pressure = 0.352 (Mathers, 1999) • Primary insomnia = 0.100 (WHO, 2007) • Sleep disturbance = 0.020 (Knol, 2005);0.055 (Müller-Wenk, 2005) • Annoyance = 0.010 (Stassen, 2008);0.033 (Müller-Wenk, 2005) • Cognitive impairment = 0.006 (Hygge, 2009)

  49. Economic Valuation • Common procedures for assessment of benefits • Contingent valuation (willingness to pay)Benefit of 25 € per household per decibel per year above noise levels of Lden= 50-55 dB. • (Example tyre noise study: quieter tyres could produce benefits to the public of about 48 and 123 billion €) • Hedonic pricingData from real estate market; lower value of properties exposed to higher noise levels. Best estimate: House prices loose 0.5% (range: 0.2% - 1.5%) of their value per decibel over Lden= 50-55 dB.
