A REFER result does not necessarily mean that your child has a hearing loss. A REFER result indicates that further testing is required. What does PASS/REFER mean? A PASS result indicates that your child’s hearing correlates to levels required for speech and language development at the time of the screen. The device then automatically gives a PASS or REFER result. Sensors placed on your child’s skin pick up the responses to the sound from his/her brain and send them back to the Echo-Screen device, where they are analyzed. With ABR technology, the Echo-Screen device sends soft clicking sounds to your child’s ears through either an ear probe or earphones. The Echo-Screen device analyzes your child’s response and automatically gives a PASS or REFER result. The ear probe then measures and records the sound wave responses of your child’s cochlea. Your child’s inner ear (i.e., cochlea) generates sound waves in response to the clicks or tone bursts. With AOAE technology, the Echo-Screen device delivers clicks or tone bursts through your child’s ear canal via a probe, which is inserted within his/her ear. ![]() ![]() A person does not need to interpret results or have special technical skills to operate the Echo-Screen device.
