great tractor pics Dennis. Hope you are feeling better.
couldn't nap, too wound up from driving...the Blue Route does it to me every time.
you need to take a tranquilizer pill before you get on that road.
This is the main road that goes North West out of Philadelphia near the airport if one doesn't keep going North
on Route 95 which goes through the middle of the city.
I forgot to take my sound reducing headphones on this trip, and probably why I have a buzz in my head now.
when I wear those noise cancelling headphones, not only prevents the buzz but makes the car, and primarily the rv,
much more comfortable on long trips. Around town I don't bother. It's the constant rotational road noise, the whine you hear
driving on concrete, that these phones totally dial out. I can listen to my car stereo at same time and hear the music.
I'm sure the highs are muffled but it's very listenable. The Volvo has a good B&O stereo in it and cranked up it is surprisingly
good, for a guy with bad hearing.
I also find them a must while mowing. Not just less noise, the irritating part of it simply eliminated.
pilots have been using this for a long time.
I've tried the 70 dollar ones from Amazon, and for mowing
the lawn they are wonderful. But there really is a difference wearing my Sony or I'm sure a Bose. And my Sony was only a mid level model.
What you want is the good sounds coming
through, not the bad sounds. Involves a number of built in microphones sampling the noise and then it does its electronic voodoo.
I think it's more than just a filter, think it involves some kind of white noise injected to mask the bad noise.
Most importantly, and I've tested this, I can hear sirens just fine. Sirens warble, they aren't steady state noise.
So somehow the electronics figures that out and doesn't suppress it that much. A lot better than hearing a siren though loud rock music
playing. Which I don't listen to...silence can be a real luxury.
time to go fiddle with plants
