Moses, I understand ultrasound is a UHF (ultra high frequency) but never thought about the dB level. I can't imagine it's very high.
BTW, if you've never been to the NHRA and you're a car guy, you need to go once in your life, at least. Watching it on the TV you have NO IDEA the amount of power going down that track. I mean NO IDEA at all.
