Sound & Noise Meters

Pick based on intended use: simple hobby or home checks can use basic A-weighted handheld meters, while professional, industrial, or legal measurements require Class 1 or Class 2 meters with calibrated accuracy, data logging, and selectable weighting (A/C) and response times (fast/slow)

Look for meters conforming to IEC 61672 or ANSI S1.4 standards; Class 1 offers higher accuracy and wider frequency response than Class 2. Check the specified tolerance (e.g., ±1 dB) and whether the manufacturer provides calibration or traceable calibration certificates

Battery life varies by model and features; many handheld meters run 8–40 hours on standard batteries, and some offer USB rechargeable batteries or external power. If extended field use is needed, choose models with rechargeable packs or low-power modes and carry spares

Yes—periodic calibration ensures accuracy; light users can do annual checks while critical applications may need more frequent calibration. Calibration can be done with an acoustic calibrator (94 or 114 dB at 1 kHz) or returned to a certified lab for traceable calibration

Essential features include measurement class (1 vs 2), weighting (A/C), response times, and a reliable microphone; higher prices reflect better accuracy, extended frequency range, data logging, octave band analysis, and rugged or IP-rated housings. Budget options under $50–$100 suit casual use, while professional meters cost more

Protect the microphone with the included windscreen, store the meter in a dry case away from dust and extreme temperatures, avoid dropping it, and perform regular calibration checks; replace or recharge batteries before long deployments
