Precision AirConvey
Sound Attenuation
Precision AirConvey's inline sound attenuation devices have been documented to reduce sound pressure levels without sound attenuation from 95.5 dBA to 79.8 dBA when installed near the face—where most of the sound in a pneumatic conveying system is generated. The 16.4 percent reduction supports compliance with 29 CFR 1910.95.
Extech Instruments
Sound Monitor
Extech Instruments' new SL130 Sound Level Monitor features both internal alarm illumination and external alarm output. Designed for worker safety compliance, the monitor is ideal for industrial environments--such as factories, plants, refineries, and mills--where there is a need to generate an alert when sound levels exceed a pre-set limit.
Noise Dosimeters
Scantek Inc.'s two new noise dosimeters from CESVA, the DC-112a and DC-112k, both comply with the ANSI S1.25-1991 Class 2 standard and are designed to protect workers against exposure to noise. The instruments allow the use of frequency weightings, time weighting, and exchange rates, and measure simultaneously using two programmable threshold levels.
Noise Recorder
Scantek Inc.'s newest product, the Noise Nuisance Recorder N-140NNR, is contained in a small, tough, lightweight case to prevent damage, and a padlock to prevent interference. Levels are logged once per second (or faster if necessary) for accurate detection of impulse noises like barking dogs or banging on walls.
Quest Technologies Inc.
CABLE-FREE DOSIMETER
Quest Technologies' The Edge is a cable-free noise dosimeter that is designed to measure personal noise exposure. The thin, lightweight, contoured, shoulder-mount instrument conforms to a worker's body for comfortable use while maintaining an upward orientation for its microphone. Available features include datalogging and time history with instant data review via the device's LCD viewing screen.
Quest Technologies Inc.
SOUND METERS
Quest Technologies' two new products--The Verifier and Quest SoundPro® Integrating Sound Level Meter models SE and DL--are designed for the evaluation and certification of Speech Intelligibility through fire alarm, mass notification, and other PA systems. The devices feature a digital readout in order to take the guesswork out of knowing whether a user is in compliance. Booth 872.
Casella USA
MICRO DOSIMETER
Casella's CEL-350 dBadge Micro Noise Dosimeter is designed to provide all of the power of larger dosimeters in a smaller, lighter package that is similar in size to a modern flip phone. Providing simultaneous measurements with 5 dB and 3 dB exchange rates, the datalogging device has a built-in cable-less microphone and can provide for any combination of settings in every measurement. Booth 1633.
Larson Davis Inc.
NOISE DOSIMETERS
All Larson Davis Spark® series of personal Noise Dosimeters and the SoundTrack LxT® Sound Level Meter offer automatic calculation of Noise Dose and Time-Weighted Average noise levels, as well as maximum and peak exposure levels, which are required to meet the American National Standards Institute (ANSI) Standard A10.46-2007.
