Appendi x B Sound Examiner SE - 400 Series 34 Glossary of Terms dB Sound Level Meters use the decibel as the unit of measure known as Sound P res sure Level (S PL). SP L uses the ratio between a reference level of 20 microPascals (.00002 Pascals) and the level being m easured.
Appendi x B Sound Examiner SE - 400 Series 35 due to a telephone ringing near the instrument, then only those seconds will contribute to the L AVG resulting in a lev el perhaps around 40 dB (notably lower than the actual levels in the environment). L EQ The true equivalent sound level measured over the run time.
Appendi x B Sound Examiner SE - 400 Series 36 Overload (OL) An overload will occur whenever the input signal exceeds the dynamic range of the instrument. Pascal (P a) Unit of pressure equal to 1 Newton per square meter. Referen ce press ure The sound pressure at the threshold of human hearing, as measured under standard conditions.
Appendi x B Sound Examiner SE - 400 Series 37 F igure B- 3: Fast respons e to a ton e burst SPL /L AS 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 r is the reference pressure.
Appendi x B Sound Examiner SE - 400 Series 38 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.
