NCT04231396

Brief Summary

The goal of the proposed project is to create an Audiobooks for Hearing Loss (HL) App - an audiobook App that has a wide array of user-selectable features designed to provide auditory training. The effects of the Audiobooks for Hearing Loss App as Auditory Training for those With CI and HA Users was measured with a 6-week trial of using the app and measuring changes in listener abilities and adherence to the program.

Outcome Measures

Primary Outcomes (1)

  • Audiobooks Efficacy: Change in Slope of Curve for SNR Loss Scores on a Scale/Week for Partial BKB-SIN Hearing Test

    Speech in noise test; partial BKB-SIN hearing test. SNR Loss scores based on normative sample data on decibel (dB) measures. where Minimum value is 0 dB, Maximum value 15+ dB. Lower scores mean better outcome, 0-3dB = hearing normal; 3-7 dB = Mild SNR loss; 7-15 dB = Moderate SNR loss; \>15 db = Severe SNR loss. Slopes of BKB-SIN (Background Noise partial tests) were measured from the Auditory Training portion of the study: weeks 7-12. We used a smoothing method for statistical analysis: isotonic regression (isoreg(), via R). This method is the fundamental assumption that the scores of these 6 weeks will be non-increasing indicating better outcome; improved listening scores on the BKB-SIN partial tests.

    6 weeks

Secondary Outcomes (2)

  • Audiobooks Positive Responses: Percentage of Positive Responses to Final Usability Survey Question: Would You Buy or Recommend Audiobooks for HL App as Auditory Training

    6 weeks

  • Audiobooks Adherence: Overall Mean Score of Weekly Goals Met for HA and CI Users Using the Audiobooks for HL App as an Auditory Training Program

    6 weeks

Study Arms (1)

HA and CI Users using Audiobooks for Hearing Loss for Auditory Training

OTHER

study participants will be seen weekly for 12 weeks and will use the Audiobooks for HL App for the final 6 weeks using the App at least two hours per week on their own. The researcher will conduct 12 weekly in-home visits where the following will be done: First 6 weeks: • Partial BKB-SIN will be administered Final 6 weeks: * Partial BKB-SIN will be administered * Conduct a comprehension test. * Address any usability issues the participant brings up. * Review and set new weekly goals Final session: Conduct Final Usability survey

Eligibility Criteria

Age9 Years - 90 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • \*Because of the COVID-19 Pandemic and low enrollment numbers for certain HL subgroups in the study, the effectiveness of the Audiobooks for Hearing Loss App was measured for the overall group.
  • Participants had to fall into one of the following five HL subgroups: (1) Adults with HA, moderate HL (41-55 dB); (2) Adults with HA, moderately-severe to severe HL (56 to 90 dB); (3) Adults with non-recent CI, post-lingually deaf; (4) Children, ages 9+, non-recent CI, pre-lingually deaf; and (5) Adults and Children, ages 9+, recent CI, post-lingually deaf. These five subgroups span broad ranges in terms of: (1) age (adults vs. children); (2) severity of hearing loss; (3) device used (HAs vs. Cis); (4) familiarity with device (recent vs. longer-term); and (5) onset of HL (pre-lingual vs. post-lingual. The team expects the highest efficacy for children and adults with recent CI who are post-lingually deaf; the lowest efficacy for adults with HA with either moderate of severe HL; and intermediate efficacy for children with non-recent CI who are pre-lingually deaf.
  • speaking English as first language,
  • and being able to read at least a first-grade level.

You may not qualify if:

  • no suspicions of cognitive deficits or vision impairments that would interfere with system usage or invalidate usability assessment,
  • no signs of external ear disease,
  • and all participants will be tested with the Expressive One-Word Picture Vocabulary Test, 4th Edition (EOWPVT-4; Brownell 2000), normed for ages of 2 and older, and are required to score in the 15th percentile or better.

Limitations and Caveats

COVID-19 impacted enrollment causing an imbalance of subgroup numbers for comparisons, so the effectiveness of the Audiobooks was measured for the overall group. The partial BKB-SIN hearing test that was given weekly consisted of 4 lists of sentences vs. the comprehensive BKB-SIN hearing test, which is comprised of 36 lists of sentences. The smaller sample size; number of items used on the partial BKB-SIN hearing test often produced significant variability which can lead to unreliable data.
