Since I can out myself as working for a wind turbine manufacturer I know that noise an interesting phenomena. You don't perceive the same noise level as the same at day and night. Things always seem louder at night because your senses change as you get ready to go to sleep. During the day there are also tons of other noises going on. That is why in Germany the noise level for a wind turbine on a residential house (we don't make the big ones) must be below 60dz during the day and 45 at night. Technically you also have more wind at night but I don't get the study behind that
