Background: The International Outcome Inventory for Hearing Aids (IOI-HA) is a seven-item hearing-specific questionnaire. It was developed with the purpose of evaluating the efficacy of hearing aid rehabilitation. Few psychometric properties have been presented for a Swedish translation of the IOI-HA. Furthermore, previous studies have examined the IOI-HA in mainly sensorineural hearing losses, and we do not know how the type of hearing loss affects the outcome. Purpose: To evaluate the hearing aid fitting outcome measured in a clinical setting using a Swedish translation of the International Outcome Inventory for Hearing Aids (IOI-HA), to determine the psychometric properties of the translation, and to examine how a number of demographic variables such as type of hearing loss affect the outcome. Research Design: A descriptive and correlational study in a retrospective sample. Study Sample: Two hundred and twenty-four (107 females and 117 males; ages 27–94 yr with an average of 66.1 yr) first-time hearing aid users. Intervention: Mostly digital hearing aids (97.8%) were fitted monaurally (60%) or binaurally (40%) between 2007 and 2009. Data Collection and Analysis: The subjects were mailed the IOI-HA questionnaire six months after their final appointment, and the completed questionnaire was returned by mail to the clinic. The psychometric properties were evaluated and compared to previous studies using the IOI-HA. The associations between the outcome scores and a number of demographic variables (age, gender, degree of hearing loss, type of hearing loss, number of hearing aids, and type of hearing aids) were examined. Based on the pure tone audiograms, the subjects were divided into three groups; those with conductive hearing losses, sensorineural hearing losses, and mixed hearing losses. For these groups, the differences in outcome measured as IOI-HA were examined. Results: The psychometric properties of the present translation of the IOI-HA showed resemblance in many aspects to previous reports. Furthermore, the type of hearing loss seems to affect the IOI-HA outcome. Hearing loss increases with increasing age, and hearing aid use increases with increasing degree of hearing loss. Subjects with sensorineural hearing losses show significantly poorer scores on items concerning introspective aspects of the outcome in comparison to subjects with mixed hearing losses and subjects with conductive hearing losses. Monaurally fitted subjects tend to report lower scores on average, but monaural or binaural hearing aid fitting do not significantly affect the subjective outcome. Conclusions: The psychometric properties of the present Swedish translation of the IOI-HA show resemblance in many aspects to previous reports, but the differences observed could be due to differences in the study populations. Overall, the demographic variables examined could not be used as predictors for the hearing aid fitting outcome, and more reliable predictors need to be identified.

Directional Benefit

An acceptable noise level (ANL) procedure for measuring hearing aid directional benefit was compared with masked speech reception threshold (SRT) and front-to-back ratio (FBR) procedures. ANL is the difference between the most comfortable listening level and the maximum accepted background noise level while listening to speech. Forty adult subjects wearing their own binaural hearing aids were evaluated in omnidirectional and directional modes. The subjects were fitted with a variety of hearing aids by clinical audiologists, independent of the study. For each procedure, speech and noise were presented through loudspeakers located at 0° and 180° azimuth, respectively. Mean ANL (3.5 dB), SRT (3.7 dB), and FBR (2.9 dB) directional benefits were not significantly different. The ANL and masked SRT benefits were significantly correlated. The ANL appears to be a quick, clinician/user friendly procedure for measuring hearing aid directional benefit.

The Relationship

A custom in-the-ear (ITE) hearing aid fitting was compared to two over-the-ear (OTE) hearing aid fittings for each of 9 subjects with mild to moderately severe hearing losses. Speech intelligibility via the three instruments was compared using the Speech Intelligibility Rating (SIR) test. The relationship between functional gain and coupler gain was compared for the ITE and the higher rated OTE instruments. The difference in input received at the microphone locations of the two types of hearing aids was measured for 10 different subjects and compared to the functional gain data. It was concluded that (a) for persons with mild to moderately severe hearing losses, appropriately adjusted custom ITE fittings typically yield speech intelligibility that is equal to the better OTE fitting identified in a comparative evaluation; and (b) gain prescriptions for ITE hearing aids should be adjusted to account for the high-frequency emphasis associated with in-the-concha microphone placement.

AbstractConservative treatment for otitis media with effusion (OME) led us to consider the use of hearing aids as a way of managing the associated hearing loss. This study aimed to assess the compliance of patients and acceptance of hearing aids for the management of children with OME.Thirty-nine children who had been given binaural hearing aids to manage OME were assessed at routine follow-up after six months. A clinician who did not prescribe the aid administered a questionnaire to assess compliance, change in symptoms and acceptance of the aids.Thirty-eight parents thought the aids were easy to use and 25 (66 per cent) were completely satisfied with the management. Aided hearing improved by a mean of 17 dB (Range 10–30) over three frequencies, 0.5, 1.0, 2.0 Khz and all parents reported subjective hearing improvement in their children. The stigma of an aid was reported as minimal under the age of seven.Hearing aids provide a non-invasive way of managing the problems associated with OME which is acceptable to certain parents and children. Long-term effects of using aids need to be evaluated before they can be recommended.

The purpose of this questionnaire study was to evaluate the existing knowledge of binaural hearing and the attitudes and practices of prescribing bilateral hearing aids amongst otolaryngologists in the United Kingdom. Of the 950 questionnaires sent to the current members of the British Association of Otolaryngologists and Head and Neck Surgeons (BAO-HNS), there were 591 respondents (62 per cent). The true response rate with completed questionnaires was 59 per cent. Eighty-one per cent of the respondents were aware of the importance of binaural hearing and had a positive attitude towards binaural fitting. The practice of bilateral hearing aid prescriptions was found to be poor amongst all grades on the NHS (less than 10 per cent of all hearing aid prescriptions). This practice in the private sector was variable, dependent largely on patient preference and affordability. The practice of binaural prescription was higher for patients in the paediatric age group than amongst adults. Two common indications for hearing aid prescriptions for unilateral deafness were otitis media with effusion in children (23 per cent of respondents) and for tinnitus masking in adults (12 per cent of respondents). Many otolaryngologists believed that there was not enough evidence to support bilateral bone-anchored hearing aid implantation and bilateral cochlear implantation. Ninety-four per cent of the respondents believed that binaural hearing was as important as binocular vision.
