what they did :
12dB is literally nothing in reduction when the lawn dudes are blasting 60-100db

12 dB is a pretty decent reduction if your goal is hearing protection, 100->88 is also bringing it to something that absolutely needs hearing protection to something that's borderline acceptable for an 8 hour shift depending on your local laws, mine say 4 hours but still, way more comfortable to use.
It’s an insignificant 2db, I don’t know why buddy didn’t provide the relevant information.
Reading the article, reducing the shriller frequencies by 12db is still pretty nice, looks like it's designed for electric blowers which are already way quieter than gasoline powered ones, already generally in the hearing safe range. 2db overall should still be noticeable though, be generally less annoying.
