Sound measuring equipment is the first step to reducing workplace noise

Identifying areas or operations with excessive exposure is the first step to improving your workplace.

Instruments for occupational noise measurements are called sound level meters and noise dosimeters.

Why is monitoring noise in the workplace important?

Noise is one of the most common occupational health hazards. It’s a risk in every industry from manufacturing and mining to restaurants and farms. Serious damage or permanent hearing loss are the main health concerns.

The noise levels in your workplace must be managed to prevent hearing damage.

Reducing noise with engineering controls is the best solution. When you cannot control the hazard, you need to consider personal protective equipment (PPE) like earmuffs or earplugs. You should also use instruments to monitor and report on the level of sound in your workplace.

Sound level meters

A sound level meter is a handheld instrument that takes noise readings of an environment. Industrial hygienists measure sound to assess sources of noise, like machinery, that need to be controlled, and define which areas require hearing protection devices.

Sound level meters come in a variety of forms that can measure with or without weighted averages and typically have the ability to provide octave band filters that can separate noise levels into their respective frequencies.

Sound level meters are available in two classes:

  • Class 1 Sound Level Meters: These precision-grade meters are ideal for laboratory use, environmental applications, boundary noise, building acoustics and traffic assessments.
  • Class 2 Sound Level Meters: These general-grade meters are ideal for noise-at-work assessments, basic environmental measurements, entertainment noise, construction noise and vehicle noise.

Noise dosimeters

What is a noise dosimeter? A noise dosimeter gives an industrial hygienist an estimate of the true noise level a worker experiences for the duration of their shift. 

It helps the hygienist assess areas that require additional engineering controls or hearing protection devices. Workers wear the noise dosimeter near their ears for the duration of their shift.

Acoustic calibrators

An acoustic calibrator is a device that produces an acoustic pressure of a defined level and frequency to create a template. Using this template, you can check the accuracy of the measurements performed with the sound level meter and/or calibrate it if an error occurs.

  • Calibrates class 1 and class 2 sound level meters and dosimeters with 1/2″ microphones

SV 36

SV 36 Class 1 sound calibrator

Class 1 sound calibrator

  • Infrared sensor detects microphone presence
  • Built-in microprocessor
  • Designed for calibration at 94 dB and 114 dB at 1 kHz frequency

SV 34B

SV 34B Class 1 sound calibrator

Class 2 sound calibrator

  • Generates a 114dB reference signal at 1 kHz
  • Designed to calibrate class 2 sound level meters and noise dosimeters with 1/2″ microphones

Occupational noise measurement software


Supervisor Lite is a PC software designed to support occupational noise and vibration measurements.

The software automatically detects noise dosimeters, sound level meters and vibration meters for data download and configuration.

Supervisor Lite introduces the new validation tool. This module allows for fast and easy result validation by removing erroneous data including:

  • invalid noise sources
  • shocks to the instrument, and
  • data that was gathered when the dosimeter wasn’t properly worn.
