I have done quite a bit of measuring on the tools that I use. Both with a dB meter and iPhone/Apple Watch. I would say that around 95 dB is reasonable for cross cutting fence boards. Rip cuts gets louder for some reason, usually up to about 100 dB on my circular saws.

Interesting, I think this aligns with what we have seen before, insertion depth and fit is important, but for some people you might not reach enough protection with only earplugs, depending on the shape of your ear canals and how deep you manage to insert the earplugs. For myself, when I need...

I think we have discussed this in the past, I think your post is a bit misleading. The 16-year-old study you are referring to was done on the old classic M3 earplugs that has an SNR rating of 28 dB, fully inserted they reach 22 dB protection, according to the study. Modern earplugs like the 3M...

I have had something similar happen to me twice in the last 6 months. The first time I lost about 30-40 dB a @ 500-1000 Hz. The hearing came back after about 12 hours. The doctor thought it was sudden deafness and I got Prednisolone (the hearing returned before I started the Prednisolone). The...

If your Apple Watch says 95 dB I would trust that. The watch is doing some kind of averaging so fast peaking sounds might not show up correctly but a car starting up should be slow and stable enough to be detected.

I have been using Nasonex for allergies, during the summer months for years without problems, but since my tinnitus got a bit worse last fall it actually seems to cause a high frequency spike. Not sure what to do this summer, I think there are some alternatives without corticosteroids but they...

Thanks, they don't really say how they came to that conclusion but from what I can see it's 22 dB when fully inserted. So SNR -6dB for that specific earplug.

Do you have any more information about that study? I have seen those numbers mentioned before but they seem quite low compared to other sources.

But the * 0.5 to 0.8 must surely be to compensate for improperly fitted hearing protection? Whenever I see someone using earplugs they almost always have them halfway inserted, and in that case the * 0.5 reduction for OSHA makes sense.

Sure, there will always be some reduction in effectiveness, but properly fitted and sized foam earplugs should be quite close to the SNR rating, or at least within 5-10 dB (I think UK health and safety specify 4 dB?).

85 dB with good earplugs would be about 50-55 dB reaching the ear, right? I guess it boils down to your personal noise tolerance, driving a modern car is about 55-60 dB, if you can do that without earplugs and without problems you should be fine. Over protecting is a real problem, spikes (or...
