Used an app to measure the sound levels of my electric razor: It is 80+ dB. I had always felt that it was very loud but hadn't done anything about it. Now, I have started using it with regular earplugs and it is much better!

The blender in my kitchen is likely 90+ dB - planning to use earplugs for it.

I realized only recently that the decibel scale is a logarithmic scale. So, compared to 60 dB, 80 dB is 100 times more intense and 4 times louder.

Musical instruments that my kids play are at 90 - 95 dB - dangerous sound levels. Ordered some "music earplugs" that won't muffle the sound...
