Audiometer Repair
Circuit-Level Diagnostics & Electroacoustic Validation
Service Summary
Medology's repair technicians perform circuit-level diagnosis and repair on all major audiometer platforms. Every repair is followed by full electroacoustic validation against ANSI S3.6 tolerances before the instrument is returned to service — ensuring repaired units meet the same performance standards as a newly calibrated instrument.
Why It Matters
A malfunctioning audiometer produces unreliable thresholds that can result in clinical liability, failed audits, and harm to patients.
Post-repair calibration is required by ANSI S3.6 — a repair without re-calibration does not restore compliance.
Medology maintains OEM-sourced transducers, earphone cushions, and headband assemblies for fast parts replacement.
Detailed repair documentation supports warranty claims and provides traceability for the instrument's service history.

Service Workflow
Intake & Symptom Assessment
Technician reviews reported symptoms, service history, and performs a visual inspection for physical damage before opening the unit.
Electroacoustic Fault Isolation
Full measurement against ANSI S3.6 tolerances identifies which parameters are out-of-spec to isolate the fault to a specific subsystem.
Component-Level Repair
Circuit board repair, transducer replacement, mechanical adjustment, or firmware update as needed. OEM parts used where available.
Post-Repair Calibration & Return
Full calibration performed after repair. NIST-traceable certificate issued. Unit returned with repair report and 90-day warranty.
Standards & Regulations
All repaired audiometers undergo post-repair calibration to ensure they meet the same compliance standards as a newly calibrated instrument.
Post-repair calibration must confirm all parameters are within ANSI S3.6 tolerance before return to clinical use.
Medology's repair procedures follow ISO 9001 quality management principles for documentation, traceability, and customer communication.
Relevant test methods referenced for thermal and mechanical stress in transducer component qualification.
Each repaired instrument is accompanied by a repair report documenting the fault, the corrective action, parts used, and a post-repair calibration certificate confirming ANSI S3.6 compliance.
