Just an anecdotal remark that points to a humongous individual differences
problem in this kind of work. Our bedroom is on the 2nd floor of our house.
I will wake up in the middle of the night if my baby daughter coughs once on
the 1st floor, even when I have yellow foam earplugs that attenuate about
25 dB. A duet of earthquake and air raid siren would not wake my wife who does
not (need to) wear earplugs to sleep. If anybody publishes waking thresholds
as general data, I wouldn't believe them for a second.
