Objectives: Hearing aids are the most common rehabilitation
choice in older adults with presbycusis. However, the choice
of the technology level today is somewhat arbitrary and typically based on individual preferences. Thus, independent
research supporting the choice of hearing aid technology
level for older adults with presbycusis is lacking. Therefore,
the main purpose of the current study was to assess the perceived hearing abilities and the reported effectiveness of hearing aids for adults with presbycusis using premium-feature or
basic-feature hearing aids. Secondly, we investigated if differences in gain prescription measured with real-ear measurements explain potential differences in self-reported hearing
aid outcomes. Material: Two types of self-reported questionnaires were used: the Inter-national Outcome Inventory
for Hearing Aids (IOI-HA) and the abbreviated form of the
Speech, Spatial, and Qualities of Hearing Scale (SSQ-12) questionnaire. In addition, insertion gain at first fit was measured for all fitted hearing aids using real-ear measurements.
Methods: The study was designed as a two-arm parallel randomized controlled trial embedded in a Danish national Better
hEAring Rehabilitation (BEAR) project. In total, 190 firsttime hearing aid users (≥60 years) with symmetric bilateral
presbycusis were randomly allocated to either a premiumfeature or basic-feature hearing aid from one of the three
hearing aid manufacturers contributing to the BEAR project. The randomization was stratified according to age (60
to 69 years, 70 to 79 years, 80≥ years), sex, and word recognition score (WRS≥80% and WRSp=0.01) scale points higher SSQ-12 speech score per item and
0.64 (95%CI: 0.2;1.1 p(n=97). With the IOI-HA questionnaire, there was no statistically significant difference in reported hearing aid effectiveness between the two levels of hearing aid technology. Higher
gains at 1 and 2 kHz were observed in premium hearing aids
compared to basic hearing aids with two of the hearing aid
manufacturers, but the opposite was found for the premium
and basic hearing aid from the third hearing aid company.
However, the variations in gain did not explain the reported
differences in hearing aid outcomes. Conclusions: Premium hearing aid users reported significantly better hearing abilities
in the speech and qualities of the hearing domain compared to
those using a basic-feature hearing aid. Thus, the study found
evidence to suggest that adults with presbycusis may benefit from using premium-feature devices. However, the statistically significant difference in reported outcomes found in
this study might not be clinically relevant for all, so clinicians
should be careful to conclude that premium devices always
yield improved outcomes for older adults with hearing loss.
