Didn't get some kind of alcoholic beverege dripped into
it, perhaps? :-)
I don't think so :-)
OK, so maybe it was Diet Coke? ;-)
My question was more to know what is the actual limit in
decibel where an electret used in a mobile phone can be
damaged by a very strong level sound exposure.
Probably, loud enough to physcially damage it in other ways.
Some people say it's 95 DB SPL which it seems low...
I've looked at the spec sheets for mics like those in cell phones, and they
specified marginally linear operation at something like 114 dB. That's not
the point of damage, that's the 10% THD point.
A train or a truck can create louder noise.
Agreed.
A car with open windows and going 70 mph might generate LF sounds in the 130
dB range.
