New sound level monitor aids in noise compliance


A new sound level monitor has been released to coincide with the World Health Organization’s World Hearing Day on March 3

The WHO initiative aims to draw attention to the global rise in hearing loss, with one key message the focus on efforts to stem hearing loss through prevention, such as reducing noise in the workplace.

This is a critical issue for health, safety and hygiene managers as noise levels higher than 85dB are not uncommon and require detailed noise prevention programmes.

Extech Instruments has now launched a sound level monitor that helps identify issues and reduce exposure to promote the long-term health of employees.

The SL130W Sound Level Alert with Alarm mounts to the wall, bench-top or tabletop anywhere in a job site and constantly monitors sound levels.

Featuring built-in LEDs that alert users when the sound level is too high or too low, the SL130W is ideal for occupational safety and health, hospital patient care compliance, public performance regulations, schools and other areas where there is a need for being alerted when sound level reaches set points.

Designed to be compliant to OSHA and meet ANSI Type 2 and EN 60651 accuracy specification, the Extech SL130W promotes safe sound levels by actively monitoring sound levels in sites such as auditoriums, ICU patient rooms and noisy workplaces.

Colour coded

Bright red flashing or green LEDs are easily visible, even in large spaces up to 30m away.

Users can configure the SL130W to activate flashing red LEDs when a sound level is too high, exceeding safe hearing limits, or too low, in settings where an audience may not effectively hear a performance.

Green LEDs indicate compliant sound levels defined by the user’s high and low thresholds (30 to 130dB).

Plus, the color coding can be reversed to suit the application requirements (such as darkly lit sites where red may be preferred to indicate normal range conditions).

Along with bright light indicators, a jumbo-sized LCD shows decibel readings and a digital bargraph to illustrate fluctuations.

A large, reverse text “OVER” text indicator also communicates excessively high sound levels detected.

To aid in high-visibility alerting, the monitor’s dedicated alarm output jack can activate a remote alarm lighting device via relay.

For optimal placement, the SL130W has numerous set-up options: tabletop or desk, wall mount, or using an optional tripod (TR100).

Additionally, the microphone swivels 180° for proper aiming and an optional microphone extension cable allows users to place the microphone up to 15 ft (5m) away for remote monitoring convenience.

The SL130W is backed by Extech’s one-year warranty and is available with optional calibration traceable to NIST. The new monitor comes complete with power adaptor and microphone windscreen. Learn more:
