20Q: Next-Level Hearing Aid Verification

---

1.  Because hearing aid analyzers now use well-calibrated speech passages we can: Test hearing aids at normal user settings when fitting to target Have automatic measurement of the aided Speech Intelligibility Index in most test systems Have automatic measurement of goodness of fit to targets in some systems Ask the patient about how they perceive loudness, clarity and balance of the speech-based test signal, creating a bridge between verification and validatation. All of the above

2.  Headphones provided with hearing aid analyzers allow us to do which of the following? Perform continuous listening checks as we are fine tuning Co-listen with the patient and ask them to be an active participant in deciding the settings they wish to use Connect the analyzer’s headphone output to the audio input of a remote microphone to provide an accessible method of listening checks for trainees or clinicians who themselves use hearing assistance technologies. Avoid talking to the patient while their hearing aid has been temporarily muted by the programming software. All of the above

3.  Fine tuning protocols for fine-tuning frequency lowering signal processing use which of the following? A synthetic “eee” vowel to test for occlusion effects A synthetic “sss” sound to test for fricative audibility A set of high-level pure tones to test for maximum output A multitalker babble to test for noise reduction activation and strength All of the above

4.  Verification tests for noise reduction signal processing could use which of the following? A synthetic “eee” vowel to test for occlusion effects A synthetic “sss” sound to test for fricative audibility A set of high-level pure tones to test for maximum output A multitalker babble to test for activation and strength All of the above

5.  Verification with advanced tests and headphone listening can provide objective measurements of device output for which of the following? The output of many types of bone-conduction hearing aids The level of user alerts from hearing aids in the ear Transmission of a CROS microphone to the other ear Aided levels of Bluetooth-streamed music via the hearing aid to the listener All of the above
