Also not to be spammy but those specific wind turbines look like they are rotating at maximum speed. very well placed!

That too, but also often the wind in an area can be coming from several directions at once especially in hilly parts, and the computers on board use the data from the sensors mounted in different locations to get the best direction to point in. That in combination with rotation speed sensors make the final decision. If the wind is too strong it will move the blades out of the flow of air & apply a parking brake till levels are safe again. :)

There is an optimal speed most turbines operate at. By turning slightly out of the direction of the wind you can get a safer more steady rotation than if it had to rely on blade tilt adjustment, which some don't have. Also, the turbines can get stuck if the system that points them into the wind has problems.
shame it wasnt a bit longer,

What Wind Turbines Sound Wind Farm 4 months ago   02:32

Industrial wind turbine noise varies with the atmosphere and terrain. Often one of the quietest places to stand near a turbine is right underneath it. It's a little like standing beneath a 400 foot tall speaker. Turbine noise is broadcast outward and is especially troublesome at night when the air near the ground is still and the air at hub height is in motion. Standing beneath a turbine in the afternoon is the way most people who do not live in wind farms make their judgement about wind turbine noise. They stand there, listen for a minute, take pictures and drive off, go home and tell their friends that wind turbines don't make noise.
People who live in wind farms know more about turbine noise than they ever wanted to, and can't just drive off. Next time you want to listen to turbines, try it at nighttime, about 1000 feet to a quarter mile downwind from a turbine to get a better idea about what all the noise about turbine noise is about.
