Noise Modes
The V90-3MW can be specified with one of five different 'noise modes'. Each mode is set in the turbine software as part of the installation, although may be changed to another mode later. Each different noise mode implies a different power curve, so that for quieter operation, some energy yield is sacrificed. Noise mitigation is managed by adjustments to the blade pitch angle.

Famous quotes containing the words noise and/or modes:
“Your next-door neighbour ... is not a man; he is an environment. He is the barking of a dog; he is the noise of a pianola; he is a dispute about a party wall; he is drains that are worse than yours, or roses that are better than yours.”
—Gilbert Keith Chesterton (1874–1936)
“Men and women are brothers and sisters; they are not of different species; and what need be obtained to know both, but to allow for different modes of education, for situation and constitution, or perhaps I should rather say, for habits, whether good or bad.”
—Samuel Richardson (1689–1761)
