Simpson Type 2 sound level systems come in a variety of configurations to meet any noise measurement requirements. Each system is composed of several components designed to work together as one integrated test instrument and output jacks that will supply an AC RMS or DC Volt signal.

The American National Standards Institute (ANSI) provides for three weighting curves: “A “, “B”, and “C”.

The “A” weighted curve more closely corresponds to the response of the ear and is specified by OSHA. The “C” curve is essentially a “flat” frequency response and can be used in conjunction with a “fast response for an approximate indication of impulse noise levels. Low Frequency noises are better monitored by the “C” curve than the “A” curve. Low frequency sounds need to be louder to be heard.

The chart below shows the relationship between frequency and relative response.

Sound pressure level calibrators are used before or after taking measurements with sound level meters and noise dosimeters. The 890-2 can adjust Simpson models 886- 2 and 884-2 or other sound level meters with a 1″ diameter Microphone. The 890-2 provides a constant 94 dB or 114 dB sound pressure level at 1 KHz (0 dB = 0.0002 Mbar). Calibrator is immune to a wide range of temperature and humidity conditions while maintaining tight output level tolerances.
