Take readings of ambient sound levels. These portable meters give you spot readings, so you can monitor workplace machinery and vehicles, comply with safety regulations, and adhere to noise ordinances.

Meters have a selectable frequency weighting—an electronic filter that adjusts the way the meter measures sound. The A weighting is similar to the response of the human ear and is used by OSHA. The C weighting is suitable for measuring the sound level of machinery.

Earplug Fit Testing Systems

In a matter of minutes, confirm your earplugs deliver the right level of hearing protection. These kits help you meet OSHA standards for protection from excessive noise. Conduct the test onsite—everything you need, including a tablet with software already installed, is included. To use this kit, you will undergo a hearing test with and without your earplugs to determine the lowest volume you can hear. The system then calculates the difference between the scores and produces a personal attenuation rating (PAR).

Once the test is complete, you’ll receive a full report to help you choose the best earplugs. The results automatically upload to cloud storage and can be accessed on multiple devices.

Sound Level Monitors

Continuously measure ambient sound levels. The display alerts you when levels either exceed or fall below your programmed thresholds. When operating the monitor with the included 120V AC adapter, four warning lights will also flash when a threshold is reached. Monitors have a microphone that rotates 180°. They can be surface mounted or propped up using the attached folding stand. These monitors cannot be sold to Canada due to import regulations.

You can select the frequency weighting—an electronic filter that adjusts the way the monitor measures sound. The A weighting is similar to the response of the human ear and is used by OSHA. The C weighting is suitable for measuring the sound level of machinery.

Use a calibrator to calibrate the monitor on a regular basis and verify that it is working properly.

Sound Calibrators

Make sure your sound level monitor or tester provides reliable readings. These calibrators have a small speaker that generates sound at precise levels, so your monitor can be accurately calibrated before each use.

Personal Sound Level Exposure Monitors

Clip these monitors on to measure your noise exposure. Also known as personal noise dosimeters, they continuously measure ambient sound levels, intensity, and duration. You’ll often see them used in factories, airports, and construction sites to help comply with OSHA regulations for noise exposure. These monitors give noise dose as a percentage of the maximum safe daily limit and alert you when levels are outside your set threshold. You can choose from preprogrammed sound level tests or program your own. Set the monitor to record automatically or program it to record samples at timed intervals.

An electronic filter adjusts the way these testers measure sound, so you can choose the frequency weighting you need. The A weighting mimics the human ear’s response to sound. It is used by OSHA to measure the risk of potential hearing damage. The C weighting measures low-frequency sounds, so it’s often used to measure the sound level of machinery. The Z weighting gives you a flat frequency response and represents the actual noise without any adjustments.

Transmit readings to your PC with the included cord. The included software lets you review stored sound measurements and analyze measurements in real time.

Use a calibrator before and after each use to keep monitors accurate and maintain compliance with ANSI standards.

Large-Display Sound Level Monitors

Mount these monitors to your wall to view the sound level of your plant from 100 feet away. This helps you continuously keep an eye on the amount of noise in your work environment to make sure it’s safe. When the sound level exceeds your programmed threshold, the numbers on these monitors will turn from green to red. The A weighting is similar to the response of the human ear and is used by OSHA.

Attach them with the mounting holes on the back. The included cord lets you transmit data to your computer.

Noise-Filtering Stethoscopes

Isolate individual sounds during inspections. These stethoscopes amplify internal sounds so they’re loud enough to hear, while the included set of headphones filters out background noise for clarity. They’re often used to detect mechanical problems and leaks. Reach the included probe into the area you’re inspecting for precise listening. All include either multiple probes or a probe extension for hard-to-reach areas.

Dial Display

Dial display stethoscopes are commonly used in vehicles to help identify issues such as worn bearings, broken gear teeth, and wind and air leaks. Set their sensitivity to match your environment using the high/low switch. High sensitivity will better detect quiet sounds but might be too reactive in loud environments. Low sensitivity is a better choice for noisy environments, since loud sounds can damage your hearing when further amplified.

Digital Display

Digital display stethoscopes are an upgrade from those with a dial display. Designed for sophisticated machinery, they’re often used to inspect precision bearings. A user-friendly screen makes it easy to operate these stethoscopes with no special training. Volume levels are displayed both in digits and graphs so you can accurately compare across multiple measurements. An output jack lets you connect a recording device to document sounds, so you can play back noises to track progress and confirm issues are resolved. They come with recorded example noises to teach you the sounds of both functioning parts and specific problems—a damaged outer ring, for example—so you can pinpoint issues before opening your equipment.

Touch-Screen Control

Attach microphones to different spots on running machines or vehicles to amplify squeaks, knocking, and rattling from worn parts. To help you isolate sounds, these stethoscopes come with headphones that reduce background noise.

Dial Control—Stethoscopes with a dial control connect to six microphone clamps with color-coded wire leads. Turn the dial to listen to each one in turn, so you can pinpoint the source of a sound.

Touch-Screen Control—Stethoscopes with a touch screen control let you select and mute each microphone on a bright LCD screen. They include both color-coded wireless transmitters and microphone clamps—you can mount them separately to listen in on hard-to-reach spots.
