Earfit Testing with 3M™ E‑A‑Rfit™ | Pre‑Employment & Occupational Hearing Checks – Djinda Health

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.

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 (3m.com.au).

  • Objective & Accurate: Bypasses subjective methods—measures real protection from inside and outside the ear (3M Malaysia).

  • 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 (3m.com).

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