Welch Allyn OAE Hearing Screener

Yes, the Welch Allyn OAE Hearing Screener is specifically designed for rapid hearing screening of newborns and infants, requiring minimal cooperation during the test.

Yes, the Welch Allyn OAE Hearing Screener is designed for ultra-rapid screening, which is crucial when testing newborns, infants, and young children who may not cooperate fully. Its speed and efficiency make it ideal for high-throughput clinical and school health settings.

Key factors that ensure this rapid, accurate testing include:

• Fast Bilateral Screening: Tests on both ears are completed in approximately 8 to 16 seconds.
• Simple Operation: The system is user-friendly, requiring only three button pushes to execute a complete test.
• Noise Management Technology: This advanced feature mitigates ambient sound interference, ensuring reliable results without the need for time-consuming retests.

Yes, the Welch Allyn Data Manager Software is included, providing robust capabilities for patient data archiving, management, and professional reporting.

Key features of the data management system include:

• Onboard Storage: The handheld unit stores up to 250 test results directly on the device. Test data is retained even if the battery fully depletes.
• Data Transfer: Communication with the PC database software is flexible, utilizing either a Micro-USB cable or a wireless connection. The charging cradle facilitates both power and data communication.
• Reporting & Export: Patient reports can be archived and exported in professional formats, including PDF, RTF, and Image files.
• Patient Records: The system supports optional storage of patient names on the unit for easy identification.

The Welch Allyn OAE Hearing Screener tests hearing across four key speech frequencies crucial for comprehensive pediatric assessment. The specific frequencies tested are:

• 2 kHz
• 3 kHz
• 4 kHz
• 5 kHz

To achieve a valid “Pass” result using the DPOAE screening protocol, a minimum of three of these frequencies must meet the required 6 dB Signal-to-Noise Ratio (SNR) criterion. The entire screening process is very rapid, often completing both ears in approximately 8–16 seconds.

The Welch Allyn OAE Hearing Screener comes complete with everything required to perform screenings and manage patient data effectively. The standard kit includes:

• Handheld Unit: Features a clear OLED color display for easy navigation.
• Probe: Includes an integrated microphone and receiver for precise testing.
• Data Management: Database software and a Micro-USB connector for seamless PC communication.
• Charging: Micro-USB charging cable and connector.
• Essential Accessories: Disposable ear tip kit and tubes.
• Documentation: User manual, quick guide, and a calibration certificate.

Depending on your clinical needs, this device is available as a Screener Only unit or a Screener with Printer configuration, the latter of which allows for on-the-spot physical documentation of test results.

The Welch Allyn OAE Hearing Screener is specifically engineered to deliver highly accurate and reliable results across all pediatric age groups using several key features:

• Advanced Noise Management Technology: This system actively filters out ambient sound interference, preventing external noise from compromising the test results.
• In-the-Ear Calibration: Before the test begins, the device performs a check to confirm the probe is securely and optimally placed in the ear canal, which is essential for maximizing measurement accuracy.
• Rigorous Pass Criteria: Accuracy is maintained using strict DPOAE screening protocols. The screener measures emissions at key speech frequencies (2, 3, 4, and 5 kHz), and a ‘Pass’ requires the detection of emissions at 3 frequencies with a minimum Signal-to-Noise Ratio (SNR) of 6 dB.
• AutoStart Check: The system ensures that the test is only initiated when conditions are acceptable, further protecting the validity of the screening.

Yes, the Welch Allyn OAE Hearing Screener utilizes Distortion Product Otoacoustic Emissions (DPOAE) technology. This is an efficient method for rapid screening of hearing in newborns, infants, toddlers, and school-age children, as it requires minimal patient cooperation.

Key features of the DPOAE screening process include:

• Speed: Tests both ears in approximately 8 to 16 seconds.
• Protocols: It employs 2 Fixed DPOAE Screening Protocols.
• Target Frequencies: Screening occurs at crucial speech frequencies: 2,000 kHz, 3,000 kHz, 4,000 kHz, and 5,000 kHz.
• Pass Criteria: A passing result requires 3 of the tested frequencies to achieve a 6 dB Signal-to-Noise Ratio (SNR).
• Accuracy: It features built-in Noise Management Technology to mitigate interference from ambient sound, ensuring highly reliable results.

Yes, the Welch Allyn OAE Hearing Screener is designed for portability and comfort in clinical environments. The handheld unit weighs only 6.4 oz (180 g), allowing healthcare providers to perform assessments easily and comfortably throughout the day.

The Welch Allyn OAE Hearing Screener is designed with reliable internal memory for efficient data management:

• The handheld unit can store up to 250 individual patient tests directly on the device.
• This data is retained on the unit even if the battery is depleted.
• For long-term archiving and professional reporting, the included Database Software allows you to view, manage, and export patient reports in formats such as PDF, RTF, or Image files.

Yes, the Welch Allyn OAE Hearing Screener utilizes a high-performance 3.6 V rechargeable lithium-ion battery designed for extended use in busy clinical environments.

• Exceptional Battery Life: The device offers up to 15 hours of continuous operating time on a single full charge, supporting high-volume screening.
• Efficient Charging: It takes approximately 4 hours to achieve a 100% full charge.
