Objectives The Children Using Hearing Devices Quality of Life Questionnaire (CuHDQOL) is a new parent-administered hearing-specific questionnaire for children fitted with hearing devices. The aim of this study was to assess outcomes for hearing-impaired children in Singapore using this measure, as well as to examine its applicability for use in a clinical setting. Materials and methods The CuHDQOL has 26 items, uses a recall period of 1 month, and is divided into three sections: parental perspectives and expectations (eight items), impact on the family (eight items) and hearing-related quality of life (QOL) of the child (10 items). Responses are made on a 5-point Likert scale, and transformed to a score from 0–100. Twenty-two parents of children with hearing aids and 14 parents of children with cochlear implants completed the CuHDQOL. Results The mean total CuHDQOL scores was 62/100 for the children using hearing aids and 53/100 for children with cochlear implants. Scores for the children using hearing aids were higher across all subscales, with a linear regression showing this to be significant for the parental perspectives and expectations subscale (B = −10.58, P = 0.041). Analyses of Variance showed that both the ‘Parent Perspective and Expectations’ and the ‘Hearing-related QOL’ subscales were significantly higher than the ‘Impact on Family’ subscale for both groups (P ≤ 0.003). Conclusions The CuHDQOL was found to be a simple, efficient questionnaire that could easily be incorporated into clinical practice to provide a more holistic evaluation of a child's outcomes post intervention, and/or to monitor their progress over time. © 2016 Elsevier Masson SAS Source

Issue addressed: Safety is a health issue and a significant concern in disadvantaged communities. This paper describes an example of community-initiated action to address perceptions of fear and safety in a suburb in south-west Sydney which led to the development of a local, community-driven research project. Methods: As a first step in developing community capacity to take action on issues of safety, a joint resident-agency group implemented a community safety mapping project to identify the extent of safety issues in the community and their exact geographical location. Two aerial maps of the suburb, measuring one metre by two metres, were placed on display at different locations for four months. Residents used coloured stickers to identify specific issues and exact locations where crime and safety were a concern. Results: Residents identified 294 specific safety issues in the suburb, 41.9% (n≤123) associated with public infrastructure, such as poor lighting and pathways, and 31.9% (n≤94) associated with drug-related issues such as drug activity and discarded syringes. Conclusions: Good health promotion practice reflects community need. In a very practical sense, this project responded to community calls for action by mapping resident knowledge on specific safety issues and exact locations and presenting these maps to local decisionmakers for further action.

The evaluation of hearing aids (HAs) inside realistic sound environments is of increasing interest. Higher-order Ambisonics (HOA) has been used for loudspeaker-based sound field resynthesis and HOA recording microphone arrays are available. Although HOA has been evaluated perceptually, it is unclear how far the results can be transferred to evaluating HA technologies (particularly multi-microphone enhancement algorithms). In order to determine the minimum HOA order required for HA testing, an HOA framework was developed, simulating the entire path from sound presented in a room, picked up by a microphone array, decoded and received at the ears of a HA-fitted dummy head. HA directivity patterns were compared between an ideal free-field and its HOA representation to evaluate the introduced error. In-room analysis was conducted to investigate the bandwidth and performance of a directional microphone in realistic situations. For a bandwidth B, the required order was found to be M≤B/600Hz for the anechoic (worst) case scenario. The presence of reverberation introduced natural room response variations across different source-receiver locations, suggesting that the acceptable HOA error can be increased. Hence, in reverberant environments the required HOA order is reduced and at least 2D HOA reproduction can be used for evaluation of HA technologies. © 2013 Acoustical Society of America. Source

The Listening in Spatialized Noise-Sentences (LiSN-S) test has been widely applied to diagnose spatial processing disorder in both normally hearing and hearing impaired listeners who are proficient in English. The overall goal of the present study is to develop a spatial listening test that assesses similar spatial auditory processes as the LiSN-S test but does not rely on speech input and thus, is language independent. Therefore a three-alternative forced choice (3AFC) stream segregation task was implemented using a series of continuously in- or decreasing tone-complexes as targets and random tone-complexes as distractors and foils. Similar to the LiSN-S test the signals were either spatially co-located or separated using non-individualized HRTFs and the difference in thresholds defined the spatial release from masking (SRM). In order to achieve similar large SRM effects (of up to 14 dB) as observed with the LiSN-S test in normal hearing listeners, temporal jitter had to be introduced. The effect of the amount of temporal jitter was investigated on the SRM as a function of tone-complex duration. The results revealed that a jitter of about 30ms in combination with a tone-complex duration of about 30ms is sufficient to elicit the desired SRM. © 2013 Acoustical Society of America. Source
