Choosing the Right Sound Meter for Your Needs
Selecting the appropriate sound level meter for your application is crucial for obtaining accurate acoustic measurements. There are several key factors to consider when choosing a sound meter:
Measurement Parameters
First, determine what acoustic parameters you need to measure. Most sound level meters can measure basic parameters like LAeq, LCpeak, LDN, etc. However, some applications require advanced analysis like octave band or vibration measurements. This will dictate the type of microphone and analyzer required.
Accuracy
Sound level meters have different accuracy grades (Class/Type 1, 2 or 3) based on conformance to metrological standards. Higher accuracy grades have stricter tolerances and are more suitable for compliance testing and enforcement. Lower grades are suitable for general purpose screening.

Frequency Weighting
Human hearing is less sensitive to low and high frequencies. Sound meters apply "A-weighting" to mimic this response. Specialized weightings like C or Z are used for acquiring unfiltered measurements across the full frequency spectrum.
Form Factor
- Handheld meters offer portability for spot measurements.
- Noise dosimeters worn by workers measure exposure over time.
- Modular or benchtop meters enable advanced testing in controlled conditions.
Data Logging
Sound level meters with data logging allow automated, long-term monitoring and recording capabilities. This helps assess noise trends over hours or days.
Software Features
Modern sound meters interface with software for remote operation, data downloading, audio recording and reporting. Useful features include real-time octave band analysis.
Budget
Finally, consider your budget constraints. Costs range from a few hundred dollars for basic screeners to tens of thousands for precision grade meters.
In summary, taking stock of measurement needs, operating conditions and budget will ensure you select the optimal sound level meter for your application.

Features to Look for in a Quality Sound Meter
Sound level meters come in varying quality and price levels depending on included features. When selecting a sound meter, here are some important capabilities and specifications to look for:
Measurement Parameters
The sound meter should measure common acoustic parameters like LAeq, LCpeak, Lmax, Lmin, etc. Specialized meters also offer octave or 1/3 octave band frequencies and capability to measure additional parameters like reverberation time (RT60).
Speed Settings
- Slow - for average noise levels
- Fast - for capturing noise spikes and peaks
- Impulse - for gunshot noise and explosions
Frequency Weightings
Quality meters provide selectable frequency weightings including:
- A-weighting - simulates human hearing response
- C-weighting - measures unfiltered sound levels
- Z-weighting - no weighting applied
Dynamic Range
A wide measurement range allows assessing both weak and strong signals. Look for 30 dB to 140 dB range.
Microphone
The microphone should have an accurate omnidirectional polar response. Higher quality electret condenser micsminimize noise interference.
Calibration
The ability to calibrate the sound level meter ensures measurements adhere to factory specifications. Internal electrical calibration and external acoustic field calibration should be possible.
Data Logging
Data logging enables automated, continuous, and remote monitoring and recording of measurements. Ensure adequate memory for extended recording periods.
Analysis Features
Time history data, frequency analysis, cumulative distribution, percentage exceeded levels, and other analysis functions allow comprehensive evaluation.
Software
PC/mobile apps add functionality like setting measurement parameters, downloading data, graphing, reporting, audio recording, etc. Check OS and platform compatibility.
Selecting a sound meter with ample features and capabilities ensures you can obtain in-depth noise level assessments for various applications.
