  • Page 41: Glossary Of Terms

    APPENDIX Appendix B Glossary of Terms Sound Level Meters use the decibel as the unit of measure known as Sound Pressure Level (SPL). SPL uses the ratio between a reference level of 20 microPascals (.00002 Pascals) and the level being measured. SPL = 20 log (measured level/reference level) Example: the SPL for 1 Pascal is 20 log (1 Pascal/.00002 Pascal) = 94 dB.

  • Page 43 Appendix B Overload (OL) An overload will occur whenever the input signal exceeds the dynamic range of the instrument. Pascal (Pa) Unit of pressure equal to 1 Newton per square meter. Reference pressure The sound pressure at the threshold of human hearing, as measured under standard conditions. This generally accepted magnitude of this pressure is 2 .00002 Pascals .
  • Page 44 Appendix B Burst duration, t (milliseconds) Figure B-3: Fast response to a tone burst SPL/L Sound pressure level. A ratio of one sound pressure to a reference pressure. Because of the enormous dynamic range of the human ear, the ratio is calculated logarithmically by the formula below, where L is the reference pressure.
  • Page 45 Appendix B Weighting (A, C, Z) SPL measurements are commonly weighted (scaled) in relation to their frequency components in order to provide a consistent basis for comparison to other measurements of the same type. The three Sound Examiner curves are plotted in Figure B-5.

  • Page 87 Data Addendum Cable and radio frequency emission (sections: 5.18.1, 5.18.2, 9.3n) The charging cable is a shielded 1 meter long USB cable. Battery voltage range and power supply (sections: 5.20.2, 5.20.3, 9.3j) The charging circuit stops charging when the battery voltage reaches its maximum of 4.1 Volts DC. The unit shuts down when the minimum battery voltage of 3.4 volts DC is reached.
  • Page 88 Data Addendum Environmental effects (section 6.1.2 and 9.3L) The typical time intervals needed to stabilize after changes in environmental conditions include: • For temperature change of 10 ºC (18 ºF) allow at least 5 minutes. • For relative humidity change of 30% (non-condensing) allow at least 30 minutes. •...
