The best sonomètre
TL;DR — Sound Level Meters (Sonometers): Sound level meters, commonly called sonometers, measure environmental and occupational noise levels. Buyers can choose between basic handheld meters for simple dB readings, advanced precision meters that meet regulatory standards, and specialized units for long-term logging, octave-band analysis, or integration with smartphones and PCs. Important categories include:
- Basic entry-level: compact, affordable, suitable for quick spot checks and DIY use.
- Professional/Type-approved: higher accuracy, calibration support, and compliance with workplace and environmental regulations.
- Logging and monitoring: continuous recording, data storage, and remote access features for long-term studies.
- Analysis-capable: octave/third-octave filters, frequency-weighting options, and advanced metrics (LAeq, Lmax, LCpeak).
Key selection criteria: measurement range and accuracy, weighting options (A, C, Z), time response (Fast/Slow), data logging and export formats, calibration method (field and laboratory), battery life, build quality, and user interface. Consider regulatory compliance if used for legal or workplace assessments. Features like windscreen quality, microphone type, connectivity (USB, Bluetooth, Wi‑Fi), and software ecosystem influence usability. For most users, a mid-range instrument with A-weighting, data-logging, and basic calibration capability offers the best balance of cost and functionality. Professionals performing legal measurements should opt for devices that conform to recognized standards and include traceable calibration. Finally, factor in accessories and after-sales support—calibration kits, replacement microphones, and durable cases extend the useful life of any sonometer.

Frequently Asked Questions
FAQ
- Q1: What is the difference between A, C and Z weighting?
A-weighting approximates human hearing sensitivity at moderate levels and is common for environmental and occupational noise. C-weighting is flatter and used for measuring peak or low-frequency energy. Z (zero) weighting is essentially unweighted, providing the raw sound energy across the instrument’s frequency range.
- Q2: Do I need a professional (type-approved) sonometer?
If measurements are for compliance, legal cases, or formal workplace assessments, choose a type-approved instrument that meets relevant standards. For basic spot checks and general awareness, an entry-level or mid-range unit is often sufficient.
- Q3: How important is calibration?
Calibration is essential for accuracy. Look for devices that support field calibration with a traceable calibrator and have options for periodic laboratory calibration. Regular calibration ensures measurement reliability over time.
- Q4: What features matter for long-term monitoring?
Key features include internal data logging capacity, power options (AC or long battery life), robust housing, weather protection or enclosures, remote access, and software for data retrieval and analysis.
- Q5: Which metrics should I look for on a sonometer?
Common metrics are LAeq (equivalent continuous level), Lmax/Lmin, LCpeak (peak), and statistical percentiles (L10, L50, L90). For frequency analysis, seek octave or third-octave filters.
- Q6: Can I use a sonometer with a smartphone or PC?
Many modern meters offer connectivity (Bluetooth, USB, Wi‑Fi) and companion apps or software for live monitoring, data export (CSV, TXT), and further analysis. Verify compatibility and file formats before buying.
- Q7: How does wind/noise environment affect readings?
Wind and reflections can bias results. Use a quality windscreen, position the microphone per best-practice guidance, and avoid reflective surfaces or shield the meter during outdoor measurements.
- Q8: What accessories should I consider?
Essential accessories include a calibrated sound source for field checks, windscreens, carrying cases, tripods or mounts, spare batteries, and cables or wireless adapters for data transfer.
- Q9: How do I choose between logging capacity and real-time analysis?
For studies requiring historical records or unattended monitoring, prioritize logging capacity and power autonomy. For on-site diagnostics and troubleshooting, real-time analysis and display features are more valuable.
