As Mark was leaving last night, we listened to the crickets. They were, of course, out in force.
Then I measured the sound level with my meter. It was only 58.6 dBA. That's only about 10 or 15 dB above the level of a typical living room. It does sound like it would be higher than that though.
I've measured my stock Mark VIII at 70 MPH, it's around 70 dBA.
I can hear them in my bedroom at night, but they just help me fall asleep.
And those little tree spiders are quiet while they eat the skeeters.
