 3.9.1 Field calibration levels
 The noise logger was calibrated with a CAL200 calibrator at a sound                                       G51 Check Item 46 ☐

 pressure level of 94.0dBA at 1kHz before and after each set of
 measurements. Calibration drift was found to be within ±0.5dB and
 therefore considered acceptable. Provided below in Table 5 are the field
 calibration dates, times and levels.
