In today’s industrial and urban environment, noise pollution has become a major concern affecting both human health and environmental quality. Whether it’s a bustling factory floor, a busy construction site, or a testing laboratory, accurate sound level measurements are essential for monitoring noise levels and maintaining compliance with national and international standards. That’s where sound level meter calibration comes into play. In Bangladesh, this service is vital for ensuring reliable results and legal compliance — and Pico Labs Ltd. stands as a trusted name in delivering precise and professional calibration solutions.
A Sound Level Meter (SLM) is an instrument used to measure sound pressure levels in decibels (dB). Over time, environmental factors such as temperature, humidity, dust, and frequent use can cause these instruments to drift from their original accuracy. Calibration is the process of comparing the meter’s readings against a reference standard to verify and, if needed, adjust its accuracy.
In simple terms, calibration ensures that your sound level meter provides accurate, traceable, and repeatable results — which is essential for occupational safety, product testing, and environmental monitoring.
Accuracy and Reliability
Without proper calibration, readings from sound level meters can become unreliable. This can lead to false conclusions in safety assessments or environmental audits.
Compliance with Standards
Organizations such as ISO, IEC, and ANSI require periodic calibration to maintain compliance. In Bangladesh, following DOE (Department of Environment) and ILO occupational noise standards also demands verified calibration.
Legal and Regulatory Requirements
Many industrial and environmental projects require certified sound measurement data. Using uncalibrated equipment could result in rejected reports or penalties during compliance inspections.
Extended Equipment Life
Regular calibration helps identify instrument wear and tear early, extending the device’s operational life and performance stability.
The calibration process typically includes:
Pre-Calibration Inspection
The meter and microphone are visually inspected for damage or contamination.
Reference Sound Source Application
A calibrator generating a known sound pressure level (usually 94 dB or 114 dB at 1 kHz) is used to verify the meter’s reading.
Adjustment and Verification
If discrepancies are found, the meter is adjusted to match the reference standard, ensuring minimal deviation.
Documentation and Certification
A traceable calibration certificate is issued, documenting all results, standards used, and environmental conditions.
At Pico Labs Ltd., we perform each step with advanced reference equipment, ensuring your sound level meters comply with international calibration standards (ISO/IEC 17025).
