The Relation between Scores on Noise Annoyance and Noise Disturbed Sleep in a Public Health Survey

The relation between responses to survey questions on noise annoyance and self-reported sleep disturbance has been analysed to gain insight in its dependency on noise source or noise type and on individual characteristics. The results show a high correlation between responses (scores 0-10) with Pearson's correlation coefficient close to 0.8 for respondents who report hearing the source. At the ...

Motorcycle Helmet Noise and Active Noise Reduction

The incidence of collisions between motorcyclists and other vehicles may be significantly reduced by research that improves the acoustic awareness of cyclists, and thus heightens the ability of cyclists to respond to unexpected incursions from the surrounding traffic. We use our hearing as an early warning system, and hearing swiftly redirects our vision and attention. This shift in gaze is cri...

Low frequency noise and annoyance.

Low frequency noise, the frequency range from about 10 Hz to 200 Hz, has been recognised as a special environmental noise problem, particularly to sensitive people in their homes. Conventional methods of assessing annoyance, typically based on A-weighted equivalent level, are inadequate for low frequency noise and lead to incorrect decisions by regulatory authorities. There have been a large nu...
