As it says in the name, this is a "sound level
meter" that is, it will indicate the sound level
as it is perceived by the human ear. Therefore
the measured sound is filtered using a curve
that mimes the sensivity of the human ear.
The International Electrotechnical Commission
(IEC) has defined several weighting schemes
that are layed down in a standard called ANSI
S1.1-1994 The curve used to match the
human ear is called A-curve. This curve is
used in the sound level meter by default.
When wanting to measure peak sound levels
the device should be switched to use the C-
curve.
