Sereda, Magdalena ; Davies, Jeff ; Hall, Deborah (2016)

OBJECTIVE:\ud This report considers feasibility of conducting a UK trial of combination devices for tinnitus, using data from the study which evaluated different listener programmes available within the pre-market version of Oticon Alta with Tinnitus Sound Generator.\ud DESIGN:\ud Open and closed questions addressed the following feasibility issues: (1) Participant recruitment; (2) Device acceptability; (3) Programme preferences in different self-nominated listening situations; (4) Usability; (5) Compliance; (6) Adverse events.\ud STUDY SAMPLE:\ud Eight current combination hearing aid users (all males) aged between 62-72 years (mean age 67.25 years, SD = 3.8).\ud RESULTS:\ud All eight participants reported the physical aspects and noise options on the experimental device to be acceptable. Programmes with amplification and masking features were equally preferred over the basic amplification-only programme. Individual preferences for the different programme options varied widely, both across participants and across listening situations.\ud CONCLUSIONS:\ud A set of recommendations for future trials were formulated which calls for more "real world" trial design rather than tightly controlling the fitting procedure.
