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. |

No engine pad here on my 1971 with stock D-Jet.
My biggest noise problem is the passenger screaming: " slow down in the corners!". |
