Two groups of hearing aid candidates will be fit with extended wear technology. One group will be fit with the commercially available models, and the other group will be fit with either the commercially available model or a new model with different fitting characteristic. After an appropriate trial period, the success rate of each group will be determined by the desire to purchase devices.
Hearing aid candidates will be assigned to either Group A or Group B. Group A will be fit only with extended wear devices that are commercially available. Group B will be fit with either the commercially available devices, or a set of devices that have a new fitting characteristic, depending on what is most appropriate and the best fit. Because extended wear devices are inserted by a hearing care professional and sit deep within the ear canal, participants will be blinded as to which devices they are wearing. After a typical hearing aid trial period (i.e. 30 days), participants will be asked to make a determination on whether they would purchase if given the option. The percentage of people that indicate a desire to purchase devices from Group A will be compared to the percentage of people that indicate a desire to purchase devices from Group B to determine if the offering of additional fitting options results in an increase in intent to purchase, or a trial to success rate.
