    Natural Bass, could this be?

    An interesting finding recently while, get this riding my John Deere 133 Lawn Tractor. Most of you know how loud a mower can be, blades engaged, RPMs flying. Well, recently, I have begun to think more about my hearing, and being able to continue to enjoy musical details as I get older.

    While in an industrial sales job YEARS ago, I accumulated a few ear plugs to protect my ears while inside various plant facilities. I decided it was time to start using these while mowing and weedeating. I have this pair that have a rubber disc design with like 2 different size discs. If you seat them properly, it's almost like they are up against the ear drum and these babies really close the sound out!

    Now to the fun part. Could it be possible for me to actually hear the low frequencies of the tractor while the ear plugs are in? Well, believe it or not, if I drive over my driveway, I can actually HEAR the rubber knobs of the tires as they hit the drive way. I swear the first time I heard this, I thought, no, this can't be! How can I hear that through all this noise and the ear plugs? This is a small noise folks!

    I then thought, yes, we learned this in HT101, about the carrying properties of LFE. So this is not an anomoly, this is the real deal. Again, last time I mowed, I took the tradition trip over the driveway, and I could again hear each and every tire knob as it contacted the drive way.

    Amazing phenominon, and a good analogy for the "carrying" characteristics of LFE.

    I want to conclude this post by encouraging each of you to take steps to protect your ears while mowing. After all, listening is the heartbeat of what we do. I for one have been lax in this area, far to long. No, not Lex, Lax.

    Good listening,
    Lex

        Thanks guys, I think your thinking Ex-lax, not lex-lax John! ROFL. Good point though, quite the pun there and I didn't even realize it.

          Ear protection is a very good idea. I wear them to concerts, the movies, and any time I'm exposed to high SPL's like calibrating someones HT

          The foam ones attenuate up to -29db depending on frequency. Since hearing damage is cumulative it always better to be safe than sorry

            Huh, huh, huh, he said Ex-Lax, Hey it's Lex-Lax. huh, huh, huh...

            Good points. In fact I think I will start carrying some of those foam ones to movies. While just watching the commercials last weekend, they wear so loud my wife was stuffing her ears with tissue.

              Paul you hit on a sore point for me at the movies why the hell do they have to jack the volume on comercials so much? I get the impression that they are recorded louder then the movie soundtrack and they just don't bother adjusting the gain on the amps at all...pisses me off when you walk in and can't hear a damn thing the people you came with are saying

                Movie commercials like those on TV are recorded at a higher level than the program material. This way the theater/TV station can claim that the commercials aren't being "played" (they don't change the output level of the amps) any louder than the program material, even though an SPL meter shows they are. It's a game they have been playing for years.

                  My brother-in-law has ringing in his ears because of all the loud 60’s concerts he went to. Lexman has a very good point about protecting your ears. So re-lax with earplugs.

                    Lex,

                    Any chance we'll see Silver Cats spark plug wires for lawn mowers? I think they'll transmit bass even better through earplugs.

                      Goose, it's doable, lol.

                      Nice comments guys, I think this is a worthy topic for sure!

                      Mark, thinking back, I went to a few myself that left my ears ringing bad when I left there. I never understood why they had it so loud that you couldn't even hear the music. If I go to any more concerts, I will take ear plugs.
