>>13842414they aren't concerned about noise, they'd use blades with blade tips designed for noise control if they were concerned about noise, the airplane industry only does that because they're required to for financial reasons. noise complaints stemming back to the fake, politically motivated noise complaints that were generated for anti-concorde propaganda in new york in the 1970s still resonates in the aviation industry today.
the wasteful and unnecessary "green" power industry is not regulated by the same agencies and social agendas, so companies like vestas don't put a penny towards noise control.
nobody cares half a shit about legitimate noise complaints from rural folks, only fake, politically motivated noise complaints which are created for propaganda campaigns are ever taken seriously.
