At-home Auditory Training Clinical Trial (Training)
|Presbycusis Aging Hearing Loss||Behavioral: Auditory training program Behavioral: Sham Comparator: Active Control|
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Outcomes Assessor)
Primary Purpose: Treatment
|Official Title:||At-home Auditory Training Clinical Trial|
- Profile of Hearing Aid Performance (PHAP) [ Time Frame: One time: 10 weeks post session 1 ]The PHAP is a self-report survey about the benefits provided by the patient's hearing aids in a variety of listening situations.
- Connected Speech Test (CST) [ Time Frame: One time: 10 weeks post session 1 ]The CST is an "objective" measure of speech-understanding in noise that will be obtained when the patient's are wearing their hearing aids. The patient hears standardized recordings of the speech in noise and then reports the sentences that were heard. These are scored as percent correct.
|Study Start Date:||July 2013|
|Study Completion Date:||May 2016|
|Primary Completion Date:||May 2016 (Final data collection date for primary outcome measure)|
No Intervention: Passive Control
Hearing aid alone
Auditory Training Program. Hearing aid plus auditory training
Behavioral: Auditory training program
Previous experiments performed under laboratory settings using a novel word-based auditory-training regimen have demonstrated substantial improvements in open-set recognition of words and sentences in noise. The current proposed study will investigate the effectiveness of the training regimen when used in a patient's home setting with their own hearing aids.
Sham Comparator: Active control
Sham comparator: Active control. Hearing aid plus audio-book use
Behavioral: Sham Comparator: Active Control
This is a sham intervention in which the patient listens to audio books following the same regimen as the patients receiving the auditory training.
The most common communication complaint of older adults with impaired hearing is that they can hear speech, but can't understand it. This is especially true where there are competing sounds in the background. Previous experiments performed under laboratory settings using a novel word-based auditory-training regimen have demonstrated substantial improvements in open-set recognition of words and sentences in noise. The current proposed study will investigate the effectiveness of the training regimen when used in a patient's home setting with their own hearing aids. All testing for the screening, baseline speech testing, training system orientation, and the outcomes portions of this project will be conducted in the Audiology Research Laboratory (ARL) of the Speech and Hearing Center located at 200 South Jordan Avenue. The use of the training program will be done at the subject's home.
Subjects will first come to the ARL for either one session for a hearing aid follow-up and instruction in the use of the training system (Session 1) or for one session for an initial screening to determine eligibility (Screening) followed then by Session 1. Subjects will then take home a training system that includes a tablet computer that has the training program loaded onto it, a portable loudspeaker, and some accessories. There will be three groups of subjects: (1) Hearing aid alone--no training (passive control); (2) Hearing aid plus auditory training (training); and (3) Hearing aid plus audio book use (active control). Each group will include 40 subjects. Those subjects in the training group and active control group will complete two five-week cycles of training and return to the lab for outcome measures after 10 weeks of training for the primary and secondary outcome measures. The hearing aid alone group will return for the same outcome measures as the training and active control groups, but will have no intervention between these follow-up sessions.
