The Welch Allyn OAE Hearing Screener with the model number WLS-39500-NP is a cutting-edge device designed for efficient and accurate hearing screenings, particularly for newborns and infants. This screener utilizes objective hearing screening technology to overcome challenges faced when testing young patients for hearing loss. It offers rapid screening capabilities with minimal cooperation required, making it ideal for infants and those who may have difficulty sitting still during the test. The device does not rely on behavioral responses, ensuring reliable results even from very young or uncooperative patients. Additionally, it features noise-management technology to address poor test results caused by ambient sound, in-the-ear calibration for improved accuracy, and user-friendly prompts to guide staff through the testing process seamlessly.
