Within the framework of the multi-centred HYENA study, the relationship between road traffic noise, aircraft noise and hypertension was investigated. The data collection comprised a variety of potentially exposure modifying factors, including type of housing, location of rooms, window opening habits, use of noise reducing remedies, shielding due to obstacles and lengths of exposure. The quantitative role of these factors on the relationship between noise and hypertension is explored (interaction terms, stratified analyses). Type of housing, length of residence, location of rooms and the use of noise reducing remedies modified the relationship between noise and hypertension. However, the effects were not always in the direction of a stronger association in the presumably higher exposed subgroups.
