Low Frequency Noise from Large Wind Turbines  

Author:  Danish Electronics, Light, and Acoustics

This report is part of the project “Low Frequency Noise from Large Wind Turbines — Quantification of the Noise and Assessment of the Annoyance” funded by the Danish Energy Authority, Vestas Wind Systems, Siemens Wind Power, Vattenfall Vindkraft, Dong Energy, and Eon Vind Sverige.

The main topics in the present report are:

- A general method for the assessment of the audibility of low frequency sounds both in relation to the hearing threshold and in relation to masking from background noise

- Criteria for qualified reporting of wind turbine studies

- A literature study where the datafound are compared according tot he principles mentioned above
