The purpose of this study is to systematically assess the level and spectral distribution of low frequency (LF) sounds in dwellings. Measurements of broad and narrow band sound levels have been made in 36 Dutch dwellings in 1998. In 19 dwellings there were complaints about LF noise, in 17 others no complaints had been reported. According to measured broad band and spectral levels complainants' dwellings can be divided into three categories with 'considerable', 'some' and 'no' LF sound. Measured

In cases' dwellings more narrow band LF components are present, but on average at a lower level compared to controls' dwellings. MATERIALS AND METHODS Cases/controls Cases are residents, with complaints about LF noise, from all over the Netherlands. They have participated in an earlier study of (a larger group of) LF noise complainants and their partners (as a control group), investigating personal characteristics such as age, gender, occupation, hearing threshold (at frequencies 125 Hz), self reported sound sensitivity, time spent home, psychological and health status [4] . The selection from the earlier study was
