What is Acoustics & Vibration calibration?
Acoustics & vibration calibration determines the error of sound level meters, acoustic calibrators, vibration meters and accelerometers. Techmaster’s ISO/IEC 17025:2017 lab follows the IEC acoustics standards.
Sound and vibration measurement supports occupational safety, environmental monitoring and predictive machine maintenance. Faulty instruments can misjudge noise exposure or miss mechanical faults.
Techmaster calibrates sound level meters to IEC 61672, acoustic calibrators to IEC 60942, and vibration meters/accelerometers to ISO 16063, with traceability to the SI.

Typical measurement ranges & CMC
The table below lists typical parameters & measurement ranges for this discipline.
| Parameter / Instrument | Typical measurement range | CMC / Measurement uncertainty |
|---|---|---|
| SPL | ≈ 94 / 114 dB @ 1 kHz | [Verify against scope] |
| Audio frequency | 10 Hz – 20 kHz | [Verify against scope] |
| SLM | Class 1 & 2 (IEC 61672) | [Verify against scope] |
| Vibration | per instrument range | [Verify against scope] |
| Vib. frequency | per instrument range | [Verify against scope] |
⚠ Note: The ranges & CMC below are typical reference values. Please verify against Techmaster’s official Scope of Accreditation before publishing — actual CMC depends on the reference standard, method and measurement conditions.
Reference standards & traceability
Acoustic measurements are traceable via reference acoustic calibrators/pistonphones (pascal, Pa) and vibration via acceleration standards (m/s²), referencing IEC 61672, IEC 60942, ISO 16063, traceable to the SI.
