Why would who want some neighborhoods to believe Urban Loop noise won’t be more than advertized?

…Highway planners use badly flawed techniques...

 

…the “A-weighting” scale used by officials to rate traffic noise…developed in the 1930s…ignores huge volumes of sound, the kind of low-frequency rumbling from trucks that pierces walls like they aren’t even there.

 

…State DOT doesn’t dispute that the A-scale misses lower-frequency sound.

 

…Daniel Maguire, a well-known noise expert… found…A-weighting as an arbitrary system never meant to be applied in the way federal authorities now use it.

 

Numerous studies show that low-intensity noise is at least as disruptive and potentially harmful to health as higher tones, he said.
