9.5.4 Kinds of recording
The dosimeter mode stores the following information:
T Functions: once each integration interval T has come to an end, the following values are
stored in the memory:
• Equivalent continuous sound pressure level with frequency weighting A (L
AT
)
• Equivalent continuous sound pressure level with frequency weighting C (L
CT
)
• Equivalent sound pressure level corresponding to the last integration interval T, with
frequency weighting (A) for each one of the octave bands centred on frequencies 63, 125,
250, 500, 1000, 2000, 4000 and 8000 Hz
• Peak sound pressure level of the integration interval T with frequency weighting C (L
Cpeak
)
When the measurements ends, the final results are saved:
• Equivalent continuous sound pressure level with frequency weighting A corresponding to
the measurement time (L
At
)
• Equivalent continuous sound pressure level with frequency weighting C corresponding to
the measurement time (L
Ct
)
• Equivalent continuous sound pressure level with the integration time corresponding to the
measurement time, with frequency weighting (A) for each one of the octave bands centred
on frequencies 63, 125, 250, 500, 1000, 2000, 4000 and 8000 Hz.
• Overall peak sound pressure level with frequency weighting C corresponding to the
measurement time (L
Cpeak
)
• Daily noise exposure level (L
EX,8h p
)
• Equivalent continuous sound pressure level with frequency weighting A corresponding to
the last integration interval T (L
AT
)
• Equivalent continuous sound pressure level with frequency weighting C corresponding to
the last integration interval T (L
AT
)
• Equivalent continuous sound pressure level corresponding to the last integration interval T,
with frequency weighting (A) for each one of the octave bands centred on frequencies 63,
125, 250, 500, 1000, 2000, 4000 and 8000 Hz
• Peak sound pressure level of the interval with frequency weighting C (L
Cpeak
)
• Measurement time t, integration time T and the elapsed integration time
• Date and time of the beginning of the measurement
