Pagination or Media Count:
For reasons set forth, it is recommended that for sound pressure level the reference sound pressure be 0.0002 microbar, except that in the calibration of transducers the reference pressure may be 1 microbar. This applies regardless of the medium in which the sound exists, whether in air or water. The practice should be continued of stating the reference quantity at least once in each written report.
