Cutting the Wire Part II: Fitting Wireless CROS/BiCROS Devices in Practice

Please note: exam questions are subject to change.

1. What is the meaning of the acronym CROS? Contralateral Routing of Sounds Contralateral Routing of Signals Cranial Routing of Sounds Contralateral Response on Sounds
2. Which of the following may be a consequence of a single-sided deafness? Improved spatial hearing Reduced audibility of speech sounds from poorer side Reduced audibility of noise from better ear Improved speech intelligibility in noise
3. Which is NOT a fitting goal of CROS/BiCROS fittings? Improve addressability from poorer side Improved communication in certain listening situations Reduced directional hearing Reduced listening effort
4. What are benefits from a CROS/BiCROS fitting? Improved SNR for signals from better side Improved SNR for signals from poorer side Amplification of noise from poorer side Attenuation of speech from poorer side
5. Which of the following issues is NOT a consideration in a CROS/BiCROS fitting? The microphone location on poorer ear Head diameter Earmold configuration on better ear Head shadow effect
6. Verification of CROS fittings can be based on: Real ear measurements Computer simulation Visual inspection Headphone audiometry
7. The microphone for Real ear measures must be placed in... the aidable or normal ear the deaf ear both ears on a dummy head
8. Speech tests with CROS fittings should be done presenting speech from better side, noise from poorer side speech from poorer side, noise from better side speech and noise from the back speech from the front, noise from the top
9. In a BiCROS fitting, gain presettings should be based on Common fitting rules (e.g., NAL-NL1/2, DSL[i/o]) Computer simulation Rule of thumb Linear gain settings
10. Subjective verification should be based on Questionnaires (e.g., COSI, APHAB) Phone Calls Photo documentation Computer simulation
