Veröffentlichung Noise annoyance - A modifier of the association between noise level and cardiovascular health?(2013)Objectives
The effect modifying impact of annoyance due to aircraft noise and road traffic noise on the relationships between the aircraft noise level and road traffic noise level on the prevalence of hypertension was investigated in 4861 subjects of the HYENA study (HYpertension and Exposure to Noise near Airports).
Methods
Different models were investigated either including the noise level and noise annoyance variables separately, or simultaneously, or together with an interaction term referring to the same noise source for the noise level and the noise annoyance.
Results
Significant effect modification was found with respect to the association between aircraft noise and hypertension. The association was stronger in more annoyed subjects. No clear interaction was found with respect to road traffic noise. The comparison of the magnitude of the main effects (per standard deviation or inter-quartile range) of noise level and noise annoyance variables revealed stronger associations with hypertension for the noise levels.
Conclusion
There is some indication that the noise level has a stronger predictive meaning for the relationship between noise exposure and hypertension than the reported noise annoyance (main effects). The results from the Hyena study support the hypothesis that noise annoyance acts as an effect modifier of the relationship between the noise level and hypertension.

Before the implementation of CNOSSOS-EU the national assessment methods differed in algorithms describing the sound source and propagation and furthermore in regard to input data from national databases. Additional deviations arose from different software implementations and parameter settings made by the end user. This led to the development of CNOSSOS-EU with the aim of enhanced comparability of noise maps. In the case of aircraft noise the decision was made in favor of the third edition of Doc. 29 of the European Civil Aviation Conference (ECAC). This calculation method is a highly flexible instrument enabling flight procedure modelling in any precision depending on the application purpose. An essential precondition for comparable computation results are unique specifications for individual calculation steps allowing for a uniform approach to noise mapping. Here in particular, CNOSSOS-Air still has potential for optimisation. Due to the multitude of loopholes, e.g. when modelling turns or lateral track dispersions of swathes, the calculation method is in many ways unspecified leaving the end user with a scope of interpretation. This leads to different modelling approaches which substantially complicate a quality assurance. Furthermore CNOSSOS-Air generates flight profiles using procedural steps thus requiring sound knowledge of flight procedures, particularly the setting of thrust, flaps and landing gear. Since these parameters are usually insufficiently known they must be estimated which leads to results that correspond more or less to reality. Based on the national implementation of CNOSSOS In Germany it is the intention to show how CNOSSOS-Air can be concretised to assure both quality and practicality.

Using the German noise mapping data according to the Directive 2002/49/EC of 2017 and exposure-response functions for ischemic heart disease, noise annoyance and sleep disturbance assessed by the World Health Organizationâ€Ìs Environmental Noise Guidelines for the European Region the burden of disease due to traffic noise is quantified. The burden of disease is expressed in disability-adjusted life years (DALYs) and its components. The highest burden was found for road traffic noise, with 75,896 DALYs when only considering moderate evidence. When including all available evidence, 176,888 DALYs can be attributable to road traffic noise. The burden due to aircraft and railway noise is lower because fewer people are exposed. Comparing the burden by health outcomes, the biggest share is due to ischemic heart disease (90%) in regard to aircraft noise, however, the lowest evidence was expressed for the association between traffic noise and ischemic heart disease. Therefore, the results should be interpreted with caution. Using alternative input parameters (e.g., exposure data) can lead to a much higher burden. Nevertheless, environmental noise is an important risk factor which leads to considerable loss of healthy life years. Quelle: https://www.mdpi.com
