1.3 Functions
The DC112d/DC112 measures the following functions simultaneously in all the dynamic
range (one single scale):
• Equivalent continuous sound pressure level with A and C frequency weighting,
corresponding to the measurement time t, (L
At
y L
Ct
).
• Peak sound pressure level with C frequency weighting corresponding to the measurement
time t, (L
Cpeak
).
• Equivalent continuous sound pressure level with or without A frequency weighting,
corresponding to measurement time t for each one of the octave bands centred on the
frequencies 63, 125, 250, 500, 1000, 2000, 4000 y 8000 Hz. (Only DC112).
• Equivalent daily exposure level corresponding to the measurement time t, (L
EX,8h
) with
frequency weighting A.
• Sound exposure (E), corresponding to measurement time (t).
• Noise dose (DOSE), corresponding to measurement time t, evaluated according to the
criterion level (L
C
).
• Measurement time t.
• Projected equivalent daily exposure level (L
EX,8hp
) with frequency weighting A, Projected
sound exposure (E
p
), Projected noise dose (DOSE
p
) evaluated according to the value of
the projected time (t
p
).
• Time history of the equivalent continuous sound pressure level with A frequency weighting
and integration time T.
Apart from the aforementioned functions corresponding to the measurement time, when it
carries out a recording, the DC112d/DC112 saves the time history of the following functions
every T period:
• Equivalent continuous sound pressure level with A and C frequency weighting,
corresponding to the integration time T, (L
AT
y L
CT
).
• Peak sound pressure level with C frequency weighting corresponding to the integration
time T, (L
Cpeak,T
).
• Equivalent continuous sound pressure level with or without A frequency weighting,
corresponding to integration time T for each one of the octave bands centred on the
frequencies 63, 125, 250, 500, 1000, 2000, 4000 y 8000 Hz. (Only DC112).
