Frequently asked questions
What is a sound level meter?
A sound level meter (SLM) is a handheld instrument that measures sound pressure levels (SPL) in decibels (dB), responding to sound similarly to the human ear.
What is a sound level meter used for?
Sound level meters are used to measure and manage noise from workplaces, construction sites, traffic, industrial facilities, and public environments to support safety and environmental compliance.
What is the difference between Class 1 and Class 2 sound level meters?
Class 1 sound level meters offer higher precision and are used for environmental and compliance-grade measurements, while Class 2 meters are suited for general-purpose and occupational noise assessments.
How does a sound level meter work?
A microphone converts sound into an electrical signal, which is processed using frequency weightings and time constants before displaying sound levels in decibels.
What is Leq (Equivalent Continuous Sound Level)?
Leq represents the average sound energy over a specific time period, providing a single value that reflects fluctuating noise levels.
How often should a sound level meter be calibrated?
Calibration should be checked before and after each measurement session using an acoustic calibrator. Certified laboratory calibration is recommended every 12–24 months.
How do I perform a field calibration on a sound level meter?
Attach an acoustic calibrator to the microphone, activate the reference tone (typically 94 dB or 114 dB at 1 kHz), and verify that the meter reading matches the reference level.
What standards apply to sound level meters?
Sound level meters are tested and certified under IEC 61672 standards, which define performance requirements for Class 1 and Class 2 instruments.
What measurement ranges do professional sound level meters cover?
Professional sound level meters typically measure from low ambient noise levels to high peak values, often exceeding 140 dB Peak, with frequency ranges covering audible sound and, in some models, ultrasonic frequencies.
Can sound level meters store and log measurement data?
Yes. Modern sound level meters support internal or removable memory for storing time histories, statistics, and measurement results for later analysis and reporting.
Do sound level meters support wireless connectivity?
Many professional sound level meters offer Bluetooth® connectivity, allowing users to remotely control measurements and view results in real time via mobile applications.
Are sound level meters suitable for outdoor or harsh environments?
Yes. Professional instruments are designed to operate across wide temperature and humidity ranges, making them suitable for industrial, construction, and environmental noise surveys.
What software is used to analyse sound level meter data?
Measurement data can be analysed using dedicated PC software for reporting, frequency analysis, and compliance documentation, with mobile apps available for on-site monitoring.
