Acoustic measurement precision and uncertainty for UHF70
Factors that contribute to display uncertainty
The net uncertainty of the displayed indices is derived by combining the quantified
uncertainty from three sources: measurement uncertainty, system and transducer
variability, and engineering assumptions and approximations made when calculating
the display values.
Measurement errors of the acoustic parameters when taking the reference data are
the major source of error that contributes to the display uncertainty. The measurement
error is described in
"Acoustic measurement precision and uncertainty"
