- Objective: To provide guidelines for the development of two types of closed-set speech-perception tests that can be applied and interpreted in the same way across languages. The guidelines cover the digit triplet and the matrix sentence tests that are most commonly used to test speech recognition in noise. They were developed by a working group on Multilingual Speech Tests of the International Collegium of Rehabilitative Audiology (ICRA). Design: The recommendations are based on reviews of existing evaluations of the digit triplet and matrix tests as well as on the research experience of members of the ICRA Working Group. They represent the results of a consensus process. Results: The resulting recommendations deal with: Test design and word selection; Talker characteristics; Audio recording and stimulus preparation; Masking noise; Test administration; and Test validation. Conclusions: By following these guidelines for the development of any new test of this kind, clinicians and researchers working in any language will be able to perform tests whose results can be compared and combined in cross-language studies.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: The purpose of this study was to analyze a database of completed International Outcome Inventory for Hearing Aids (IOI-HA) questionnaires obtained from over 100,000 clients fitted with new hearing aids in Sweden during the period of 2012-2016. Mean IOI-HA total scores were correlated with degree of hearing loss, unilateral versus bilateral fitting, first-time versus return clients, gender, and variation among dispensing clinics. The correlations with expectations, service quality, and technical functioning of the hearing aids were also analyzed. Method: Questionnaires containing the 7 IOI-HA items as well as questions concerning some additional issues were mailed to clients 3-6 months after fitting of new hearing aids. The questionnaires were returned to and analyzed by an independent research institute. Results: More than 100 dispensing clinics nationwide take part in this project. A response rate of 52.6% resulted in 106,631 data sets after excluding incomplete questionnaires. Forty-six percent of the responders were women, and 54% were men. The largest difference in mean score (0.66) was found for the IOI-HA item "use" between return clients and first-time users. Women reported significantly higher (better) scores for the item "impact on others" compared with men. The bilaterally fitted subgroup reported significantly higher scores for all 7 items compared with the unilaterally fitted subgroup. Experienced users produced higher scores on benefit and satisfaction items, whereas first-time users gave higher scores for residual problems. No correlation was found between mean IOI-HA total score and average hearing threshold level (pure-tone average [ PTA]). Mean IOI-HA total scores were found to correlate significantly with perceived service quality of the dispensing center and with the technical functionality of the hearing aids. Conclusions: When comparing mean IOI-HA total scores from different studies or between groups, differences with regard to hearing aid experience, gender, and unilateral versus bilateral fitting have to be considered. No correlation was found between mean IOI-HA total score and degree of hearing loss in terms of PTA. Thus, PTA is not a reliable predictor of benefit and satisfaction of hearing aid provision as represented by the IOI-HA items. Identification of a specific lower fence in PTA for hearing aid candidacy is therefore to be avoided. Large differences were found in mean IOI-HA total scores related to different dispensing centers.

Perception of disturbing sounds : Investigations of people with hearing loss and normal hearing
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The present thesis concerns the daily sound environment and the human perception of the same. The sound environment affects the possibility to be active in a communication. With background noise, it may be harder to hear desired signals, and when suffering from a hearing loss, negative effects of the background noise increase. Previous research has explored, that persons with hearing loss benefit from hearing aid usage, but there is a risk of non-usage due to low sound quality. The non-usage of hearing aids has furthermore been described as a cause of isolation and social withdrawal for persons with hearing loss.The general aim of the present thesis is to explore the concept of disturbing sounds in a daily sound environment and to examine the influence of hearing loss and hearing aid usage. Disturbing sounds were investigated in means of perception of loudness and annoyance, where loudness concerned the acoustical properties, mainly sound level, whereas annoyance concerned the psychological phenomenon, defined as an individual adverse reaction to noise. The results of studies I and II showed, that hearing aid users experience disturbing sounds more or less daily, and that those sounds resulted in a decreased usage of hearing aids. The effect of disturbing sounds seemed to rely on several factors, acoustical as well as psychological, and there was not one single factor providing a full explanation of disturbance. In study III and IV, the perception of sounds in normal hearing and hearing impaired persons were thoroughly examined and revealed that hearing thresholds affect the perceived loudness and annoyance. Furthermore, the effect of hearing aids on loudness and annoyance perception was investigated. The results showed that hearing aids restored the loudness and annoyance to levels comparable to people with normal hearing function. The results of the studies stress that additional research should focus on the implementation of knowledge of disturbing sounds in audiological rehabilitation, in order to increase the benefit of hearing aid usage.

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.
