Sound Level Meters

Sound level meters (SLMs) serve as the go-to tool for fast, accurate noise measurements in industrial facilities. Whether you are conducting walk-through assessments, verifying equipment changes, or performing environmental checks, SLMs provide the data needed to locate sources and quantify conditions.

Core Capabilities

• Real-Time Readings: Immediate SPL measurements with selectable A, C, or Z frequency weightings.
• Time Weightings: Fast, slow, and impulse options to match survey needs.
• Integrating Functions: Some models provide LEQ and other integrating metrics for expanded analysis.
• Advanced Analysis: Options may include octave or one-third octave band analysis, helping pinpoint problem frequencies.
• Data Logging: Time-history storage enables deeper investigation and clear documentation.

Use Cases

• Commissioning and acceptance testing for new equipment
• Routine floor surveys to identify hotspots
• Environmental perimeter assessments
• Pre- and post-control validation

Selection Considerations

• Performance Class: Choose instrumentation aligned with your measurement requirements.
• Analysis Features: Determine whether octave band capability is needed.
• Memory and Power: Sizing for long survey days and multiple projects.
• Software: Review download speed, charting, and report templates.

Best Practices

• Calibrate with an acoustic calibrator before and after surveys.
• Map the area to create a consistent route for repeatability.
• Use time-history and markers to correlate events with readings.
• Pair results with engineering controls or maintenance plans to reduce exposure risk.

Program Benefits

• Faster troubleshooting and prioritization of noise controls
• Clear, defensible documentation with trend visibility
• Efficient reporting for stakeholders and audits
