Bringing it All Together: Maximizing Benefits and Hearing Aid Fitting Strategies for Bimodal Patients

---

1.  What is "bimodal benefit"? Improvement in patient performance using a cochlear implant and hearing aid compared to unaided performance: (CI + HA) - Unaided Improvement in patient performance using a cochlear implant and hearing aid compared to the cochlear implant alone: (CI + HA) - CI only Improvement in patient performance using a cochlear implant and hearing aid compared to the hearing aid alone: (CI + HA) - HA only Improvement in patient performance using a cochlear implant alone compared to using the hearing aid alone: CI - HA

2.  Which fitting algorithm is recommended for bimodal hearing aid fittings in post-lingual bimodal users? NAL-NL2 Fig. 6 NAL-NL1 Proprietary fitting algorithms

3.  Bimodal phone call streaming eliminates two common problems for bimodal patients. What are these two problems? Choosing which ear to listen through and choosing the volume Choosing the phone's ringtone and finding the right volume Finding the "Sweet Spot" and improving SNR on the phone Finding the "Sweet Spot" and choosing the phone's ringtone

4.  In the bimodal fitting protocol, what MUST be completed to ensure maximum hearing aid benefit? Adding a 3rd hearing aid program Real Ear Measures Verification Applying frequency compression Disabling manual controls

5.  Unilateral cochlear implant patients and bimodal patients struggle in noise, even when optimally programming. Which Assistive Listening Device (ALD) streaming device can improve word recognition when bimodally streaming in noise? Remote Microphone technology An ear trumpet Directional microphones Wired mics

6.  To ensure a 2:1 Ratio of streaming input to hearing aid microphone input, what microphones balance setting should be selected in the fitting software? Streaming device +6 Streaming device +15 Hearing aid mic +6 Hearing aid mic +9

7.  What common problem of unilateral cochlear implant users, as well as unilateral hearing aid users, is significantly improved by utilizing hearing aid stimulation (bimodal) in the opposite ear to provide bilateral stimulation? Sounds are too loud Sounds are too soft Hearing aid provides high frequency speech information Localization

8.  Previous research shows that bimodal stimulation provides added benefit for speech understanding in noise, as well as being able to tell the difference in speech intent, such as the difference between a statement and a question. What does speech intent contribute to? Speech loudness Speech Prosody Foreign and regional accents Acting ability

9.  Which of the following is an evidence-based step in the bimodal fitting process that has shown to be a critical step for bimodal benefit? Limited bandwidth application Increasing hearing aid noise reduction settings Loudness Balancing between ears Setting hearing aid gain as low as possible

10.  Recent research suggests that pure tone thresholds averages (PTA) may be indicators for bimodal success. Which PTA may indicate bimodal success? PTA1 (500, 1000, & 200 Hz) High Frequency PTA (1000, 2000, & 4000 Hz) Parent Teacher Association Low Frequency PTA (125, 250, & 500 Hz)
