Sound Calibration Services in Saudi Arabia | ISO/IEC 17025 Traceable Acoustic Calibration by WASL

Sound calibration is the process of testing and adjusting sound level meters and acoustic level meters against a certified reference source to ensure they accurately measure sound pressure levels in decibels (dB).

Inaccurate sound measurements can lead to incorrect workplace noise assessments, non-compliance with occupational health regulations, and unreliable environmental or acoustic testing data. Calibration ensures readings are accurate and legally defensible.

Most sound level meters should undergo full laboratory calibration annually, in addition to a quick field calibration check (using an acoustic calibrator) before and after each measurement session.

ISO/IEC 17025 is the international standard for testing and calibration laboratory competence. Calibration performed under ISO/IEC 17025 accreditation ensures traceable, internationally recognized results accepted by regulators, auditors, and clients in Saudi Arabia.

Sound calibration services typically cover sound level meters used for workplace noise exposure, environmental noise, and machinery monitoring, as well as acoustic level meters used for precise sound pressure level measurement in acoustic testing.

A sound level meter is generally used for broader noise monitoring — workplace exposure, environmental noise, and equipment noise — while an acoustic level meter is used for more precise sound pressure level measurements in controlled acoustic testing applications.

Field calibration is a quick check performed on-site using a portable acoustic calibrator to confirm the meter is reading correctly before use. Full laboratory calibration is a more comprehensive process that tests the instrument across its full frequency and level range against certified references.

Yes. Accredited calibration providers issue a calibration certificate showing the test date, measured results, tolerances, and traceability to international standards — often required for occupational health and safety audits.

If a meter falls outside acceptable tolerance, it typically requires adjustment, repair, or component replacement before being recalibrated and retested to confirm it meets accuracy requirements.

Occupational health and safety, environmental consulting, manufacturing, construction, oil & gas, and acoustic engineering sectors all rely on calibrated sound measurement instruments for compliance and quality assurance.

Yes. Facilities conducting workplace noise exposure assessments are generally expected to use calibrated sound level meters to ensure measurements are accurate and meet occupational health and safety regulations.

Yes. Calibration providers typically offer both in-lab and on-site calibration options, allowing sound level meters to be tested at your facility to minimize downtime and support ongoing monitoring work.

A standard sound level meter calibration typically takes about 30 minutes to an hour, depending on the number of frequencies and measurement points tested. Bulk calibration for multiple meters is usually scheduled together.

Sound level meters are calibrated against internationally traceable acoustic reference standards, ensuring consistency with global measurement practices and compliance with applicable IEC sound measurement standards.

Look for ISO/IEC 17025 accreditation, calibration traceable to international standards, experience with sound and acoustic level meters, both in-lab and on-site service options, and certificates accepted for regulatory and audit purposes.
