OSHA says that noise over 85 dba requires a written hearing protection program.
Well I measured the sound level at 3000 RPM and I was at 87 dba. Running a 3.2 with Bens headers. Lots of free dba apps out there at no cost. Usually about +/- 1-2 error rate. OSHAs hearing protection rules say anything over 90 dba 8 hour TWA requires hearing protection. Of course these rules don’t apply to us but check out your sound measurements next time you take a drive........ (IMG:style_emoticons/default/driving.gif) Also know that 90 dba is twice as loud as 85dba. |

I dunno about too loud too old.
I do know I'm only 44 and have lost a good bit of my hearing. I'd like to try and keep whats left. My cabin got a LOT quieter after I replaced my GT lid with a stock engine lid and rain tray, and also installed the 914rubber engine side sound pad. You can have a conversation in the car now without shouting. Unfortunately it means I also hear all the other squeaks and rattles in the cabin that I never was able to hear before. Zach |
