I became familiar with Acoustical Society of America (ASA) when every “Sound Expert” (Acoustician) that testified for the Wind Companies listed being a member of ASA in their credentials.
When you join the ASA, it includes a complimentary Quarterly journal in the mail called “Acoustics Today”. It’s color, printed on high-quality paper, worth reading if you have interest in sound.
This month’s issue raised my interest with a blurb on the front page “Ambient Noise is ‘The New Secondhand Smoke'”.
This is a really good article, it talks through all the various sound levels and at what point they cause issues. It has TWO pages of References at the end to support all of it’s claims. I roughly counted 73 references.
To me, a Wind Industry skeptic, this rang true — sleep can be disturbed at 30 dB(A)[LAeq, a more constant noise] and 45 dB (LAmax, a more spiked noise). The author of the article also touches on how noise CAN find a pathway to cause physical health problems. With sources.
Some of the studies quoted, like Munzel on cardiovascular disease (2018), didn’t come out until after our hearing.
So, what we have is an article, published in a journal by an organization that the Wind Industry sound experts themselves list on their bio’s, that supports what we’ve been saying all along.
It will be interesting to see how the Wind Industry’s “Sound Experts” react. Will they attempt to discredit all 73 references?
