- A clinical trial of Oticon DigiFocus hearing aid was performed. The test aid was evaluated on 33 subjects with several years' experience as users of modern analog hearing aids. These aids were used as reference for the 1-month-long trial. The Abbreviated Profile of Hearing Aid Benefit (APHAB) showed a mean difference in benefit with superior ratings for the test aid concerning ease of communication, speech in reverberation and speech in background noise. The subjects' own aids were rated somewhat better concerning aversiveness of sounds, but this difference was not statistically significant. The Gothenburg Profile showed a statistically significant difference between the test aid and the reference aids in favour of the test aid. The difference was not most evident with regard to speech communication and the effects of hearing loss on social interactions. Sound quality ratings concerning clearness were significantly higher for the test aid. Speech recognition thresholds in noise were on average 0.7 dB better for the test aids when tested at speech levels 60 and 75 dB. The difference was statistically significant only at 75 dB. There was significant interaction between general preference and hearing aid type, indicating that overall sound quality was an important factor affecting the general preference for either the test aid or the reference aid. Twenty-three subjects generally preferred the test aid, six preferred their own aid and four stated no difference.

- Clinical experience indicates that first-time hearing aid users prefer less gain and lower maximum output levels than experienced users. This hypothesis was tested on 20 subjects being fitted with their first aids. The study was double blinded by using a programmable hearing aid, set to either the standard setting according to the manufacturer's software or to reduced gain and maximum output. Half of the subjects started with one hearing aid and half with the other, changing to the other hearing aid after 3 days trial with each setting. At the end of the study, subjects stated preference in specified situations and overall. No significant differences in APHAB, sound quality, estimated communication ability or perceived loudness scores were seen for the two settings. Nine subjects preferred the standard setting, seven the reduced setting and four were undecided. No correlation could be found between preference and audiological variables.

Konferensbidrag (refereegranskat)abstract
- Abstract:PurposeThe aim of the study is to present normative data of hearing aid rehabilitation for a Swedish population with regard to gender, age, returnclients/first time user and bilateral/unilateral hearing aid use.MethodQuestionnaires with 19 items were sent by mail to clients 3-6 months after completed hearing aid rehabilitation. In addition to the seven IOI-HAitems there were five items concerning satisfaction with reception, information and participation and seven items concerning functionality with thehearing aids.ResultsApproximately 60 000 hearing aid users returned the questionnaire during the period 2011-2014 (response rate 52.5%). Differences were foundwith regard to hearing aid experiences, gender and unilateral versus bilateral hearing aid fitting. Women compared to men and bilaterally fittedcompared to unilaterally fitted, reported significantly higher scores for all seven items in IOI-HA. The largest differences in mean score were foundfor the item hearing aid use between experienced and first-time user where experienced users used the aids more. No correlation was foundbetween mean IOI-HA score and average hearing threshold level.ConclusionWhen evaluating hearing aid rehabilitation differences between groups need to be considered.
