Original sentence: Complaints about noise have also been made.Early installations, especially the altamont pass installation used short steel towers with high rotor speeds, leading to high numbers of raptor deaths.Many opponents of wind turbines claim that turbines produce infrasound; however, measurements of wind turbine noise signatures have found that the sound pressure levels produced are too low to have any effect.Some individuals living in very close proximity to large turbine installations have voiced complaints about their visual impact.Studies of modern monolithic tower structures have shown lower impacts on bird populations
Edited sentence: Complaints about wind turbine installations near residences have included noise, electromagnetic interference and visual impact, possibly including 'flicker' caused by sunlight interacting with rotating blades on sunny days.The noise generated by large wind turbines has been described by neighbors as intrusive, causing sleep disruptions.The physical components (e.visibility, sound levels and flicker zones) of these impacts can be quantified, but whether or not they are considered negative is partly a subjective matter
