Accredited electroacoustic calibration

More than two decades of accredited experience in sound and electroacoustic measurements.

The Padua Acoustic Laboratory provides ISO/IEC 17025 accredited calibration services under ACCREDIA for sound level meters, measurement microphones, octave and third-octave band filters, acoustic calibrators and pistonphones from Senseca and other manufacturers.

Calibration methods are based on the applicable international standards, including IEC 61672-3 for sound level meters, IEC 60942 for acoustic calibrators and pistonphones, IEC 61260 for octave and third-octave band filters, and IEC 61094-5 for measurement microphones.

Depending on the instrument and requested documentation, the laboratory can issue an accredited calibration certificate or, for selected Senseca and Delta OHM sound level meters, filters and acoustic calibrators, an ISO 9001 calibration report.

Key applications for acoustic calibration

Occupational Noise & Worker Safety
Calibrated acoustic instruments support workplace noise exposure assessments, hearing-protection programmes and compliance with occupational health and safety requirements.
Environmental & Community Noise
Traceable sound measurements support environmental noise monitoring, community assessments, infrastructure studies and long-term comparison of results.
Building & Room Acoustics
Acoustic calibration supports sound insulation measurements, room acoustics, facade testing and verification activities in buildings and construction projects.
Industrial Noise & Product Testing
Reliable acoustic measurements are required for machinery noise assessment, sound pressure and sound power testing, product development and conformity verification.
Quality Systems & Compliance
Accredited calibration provides documented measurement uncertainty and metrological traceability for audits, customer qualification and certified quality management systems.
Research & Reference Laboratories
High-level acoustic calibration supports reference instruments, scientific research, interlaboratory comparisons, measurement hierarchies and uncertainty budgets.
