Comment on Students’ Leaf Blower Suppressor To Hit Retail

  Decibel scale is logarithmic, which means 10db change is reducing perceived volume by half.

    No. It means the sound energy is dropped by half. Our audio perception is also logarithmic however. It’s why we use db.

      Almost. a 10db change is a 10x difference in power and roughly 2x difference in perceived loudness

        Except if you read the information its only actually a 2 db decrease…

  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.

    The team reduced the overall leaf blower noise by about two decibels, making the machine sound 37% quieter.

    It’s an significant 2db

      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.

  Eh, I’ll take it though. I live in a fairly quiet part of town but the street has gotten pretty busy in the last could of years. And visually, I guess the street seems to open up making drivers get… spicy now and then. The fucking motorcycles, man. These noisy fucking middle-aged infants making 130 decibels while only going 15mph make me see red. I’d gladly take the lawn equipment noise.

    It’s an insignificant 2db, I don’t know why buddy didn’t provide the relevant information.

  Decibels are a logarithmic scale, so it scales exponentially. Because of this, reducing by just ten is actually very significant and would reduce the perceived volume by half, and would reduce the actual sound pressure even more than half.
