Spl level meter.

The Sound Pressure Level ( SPL) is the most basic level used in sound measurements. The SPL, measured in Decibels (dB), has been widely used since the 1930s. SPL is defined as the logarithm of the ratio of the sound pressure to a reference pressure. SPL = 20 log10(p/pref) dB. p → the instantaneous sound pressure in Pa.May 25, 2011 ...

They use two different weighting filters required by the IEC651 and ANSI S1.4 Type 2 for audio filtering.Determining the sound level is simple: set the meter’s dial on a number, such as 70. When the dial is set to 70, the needle is displaying sound pressure measurement relative to 70. When the needle hits the middle 0 position, the SPL of the sound you’re measuring is 70dB. If it reads -4, that means it is 4 under 70, or 66dB.This unit conforms to the IEC651 Type 2, ANSI S1.4 Type 2, JISC1502 requirements for Sound Level Meter. OPERATION. Press button for power ON.
