Earfit Testing Australia

Precision Verification for Workplace Hearing Protection

Djinda Health uses the 3M™ E‑A‑Rfit™ Dual‑Ear Validation System to verify hearing protection fit—essential for safety and WHS compliance.

Djinda Health utilises 3M EARfit machines for state of the art assessment of hearing protection effectiveness to ensure staff can use their Personal Protective Equipment effectively.

What is Earfit Testing?

Earfit testing is a quantitative fit test that measures the Personal Attenuation Rating (PAR) of hearing protection (earplugs or earmuffs) as worn, ensuring actual workplace effectiveness.

Why We Use the 3M™ E‑A‑Rfit™ System

  • Dual‑Ear Testing: Tests both ears at once—results in under 5 seconds using F-MIRE technology over seven frequencies.

  • Objective & Accurate: Bypasses subjective methods—measures real protection from inside and outside the ear.

  • Built for Compliance: Meets international standards including ANSI/ASA S12.71-2018 and aligns with Australian WHS and AS/NZS 1269 fit-testing best practices.

  • Interactive Training Support: Provides immediate feedback for tailored fitting guidance and preserves results in PDF reports.
