Welch Allyn OAE 39500 Hearing Screener

The Welch Allyn 39500 Series OAE Hearing Screener is a handheld, automated otoacoustic emission device designed for fast and reliable hearing screening across all ages—from newborns to adults. Lightweight and portable, it offers objective detection with minimal cooperation required, making it ideal for busy clinics, pediatric offices, and hospital screening programs.

Overview

Utilizing Distortion Product Otoacoustic Emissions (DPOAE) technology, the screener automatically evaluates cochlear function at key speech frequencies (2, 3, 4, and 5 kHz). Featuring two fixed protocols with rapid 2‑ to 4‑second test intervals, it provides pass/fail results in as little as 8–16 seconds per ear. With built-in noise management and in‑ear calibration, the device ensures accuracy even in noisy environments. Optional wireless connectivity and database software allow seamless data storage and review.
