Sound Level Systems
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.
• Meets IEC 651 and ANSI S1.4-1983 Meters
• Meets OSHA and Walsh-Healy Noise Control Specifications
• Quickly and Accurately Measures Sound Levels in Factories, Offices, Etc.
• Full coverage 40-140 dB with special 85-115 dB OSHA range
• Impact-resistant case contoured to minimize sound energy field reflections
• Operates 40 hours on a 9V battery
• AC and DC voltage jacks for recorder, analyzer and tester Interface
• Built-in tripod mount
Sound/Noise Measuring Systems
884-2 Sound Level Meter
886-2 Multi Weight Sound Level Meter
890-2 Calibrator
• Rugged solid-state reliability,
• "A" weighting
• Battery Operated
• Rugged solid-state reliability,
• "A" , “B” and “C” weighting
• Detachable microphone
• Fast and slow 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.
