Auditory acclimatisation speech in adults
No full textThe aim of this thesis was to improve understanding of the conditions required to measure acclimatisation. This should result in a more robust methodological framework for measuring acclimatisation in future studies. Three experiments were undertaken on separate groups of 16 subjects with moderate bilateral sensorineural hearing impairments. Subjects were fitted monaurally with a linear hearing instrument that provided approximately 20 dB real ear insertion gain at 2-4 kHz. The not-fitted ear was used as the control. The self-reported use of the hearing instrument was typically 8-12 hours per day. The main outcome measure was the Four Alternative Auditory Feature speech recognition test. Acclimatisation was defined as an improvement over time in recognition score in the aided ear relative to the unaided ear. In the first experiment, subjects were tested with speech presented at an overall level of 60 dB SPL at three-week intervals over a post-fitting period of 24 weeks. The results revealed an improvement in performance in both ears over time but there was no consistent evidence of acclimatisation. In the second experiment, new subjects were tested with speech presented at an overall level of 60 dB SPL at four-week intervals over a post-fitting period of 24 weeks. In an attempt to reduce the practice effect observed in the first experiment, subjects were not given trial-by-trial feedback about their performance. On this occasion, there was a non-significant trend of improving performance in the fitted ear with no improvement in the control ear. It was hypothesised that the amplified level of speech in these experiments was not sufficiently different from that experienced in everyday life, prior to aiding, to show perceptual learning. In the final experiment speech was presented at overall levels of 55, 62 and 69 dB SPL and new subjects were tested at six-week intervals over a post-fitting period of 12 weeks. There was a significant improvement in performance over time with a trend towards greater acclimatisation at the highest presentation level.</p
Sound quality judgements of new hearing instrument users over a 24-week post-fitting period
No full textThe time course of changes in perceived sound quality after hearing instrument fitting has not been studied systematically. It is possible, for example, that patients may object to additional high frequency gain when fitted, but not after a period of auditory acclimatisation. The aim of this study was to utilise sound quality judgements to compare two frequency responses in new users at 4-week intervals over a 24-week post-fitting period. The null hypothesis was that there would be no change in sound quality judgements over time. A total of 16 elderly subjects were fitted monaurally with the same model of linear, programmable hearing instrument. This was set to a standard response that provided 26–29 dB of real-ear insertion gain at 2000–4000 Hz. This program was worn by the subjects for the duration of the study. All subjects reported greater than four hours of daily use. The alternative response which was used in a paired comparison paradigm, provided a mean gain reduction of 3, 8, 13, and 16 dB at 2000, 3000, 4000 and 6000 Hz, respectively. Subjects compared the standard and the alternative responses for sound quality along dimensions of comfort, clarity, and overall preference while listening to running speech presented in quiet, steady noise, and speech babble. At the time of fitting there was a small preference for the standard response when judging clarity, but the alternative response was preferred for comfort and preferred overall. Repeated-measures analysis of variance (ANOVA) for each quality dimension did not reveal any statistically significant change over time. It is concluded that this pattern of preference is unaffected by acclimatisation to amplification, at least over the initial 24 weeks of instrument use
The influence of visual feedback on closed-set word test performance over time
No full textClosed-set word tests can be implemented with or without trial-by-trial visual feedback. Feedback is considered to increase subject motivation yet its influence on performance is unknown. The aim of this study was to compare performance on the Four Alternative Auditory Feature (FAAF) test with and without visual feedback over a 24-week period following fitting of a hearing aid. A total of 32 elderly subjects were recruited as new users and fitted monaurally with the same model of linear, programmable hearing aid that provided in excess of 20 dB insertion gain at 2-4 kHz. Half of the subjects were provided with visual feedback. In these subjects, mean performance increased by 5% across the study period. The improvement in performance over time was statistically significant on analysis of variance (p < 0.05). Mean performance did not increase in the remaining subjects who were not provided with feedback. If closed-set word tests are to be used with visual feedback to measure changes over time, the potentially confounding effects of practice must be controlled carefully. Alternatively, omitting feedback leads to simpler experimental designs
The effect of speech presentation level on measurement of auditory acclimatization to amplified speech
No full textA systematic improvement in auditory performance over time, following a change in the acoustic information available to the listener (that cannot be attributed to task, procedural or training effects) is known as auditory acclimatization. However, there is conflicting evidence concerning the existence of auditory acclimatization; some studies show an improvement in performance over time while other studies show no change. In an attempt to resolve this conflict, speech recognition abilities of 16 subjects with bilateral sensorineural hearing impairments were measured over a 12-week period following provision of a monaural hearing instrument for the first time. The not-fitted ear was used as the control. Three presentation levels were used representing quiet, normal, and raised speech. The results confirm the presence of acclimatization. In addition, the results show that acclimatization is evident at the higher presentation levels but not at the lowest

Kevin Fenton: A Reading
No full textThe John S. Lucas Great River Reading Series (GRRS) hosts Winona native and author Kevin Fenton. Fenton will read from his new novel Cyan Magenta Yellow Black published by Black Lawrence Press, 2025.
Kevin Fenton is the author of Merit Badges, which won the AWP Prize for the Novel and the Friends of the American Writers Award, and Leaving Rollingstone, which Patricia Hampl called “the most important memoir to come out of the Midwest (or anywhere) in years.” He works as an advertising writer and creative director; in that capacity, he’s published essays in the design quarterlies Émigré and Eye (London), the anthology Looking Closer 2: Critical Writing On Graphic Design, and the UX design blog Boxes and Arrows. He got a slightly better education than he deserved at Beloit College, the University of Minnesota Law School, and the University of Minnesota MFA program. He lives in St Paul with his wife Ellen and his greyhound Evie
'Web of Life' - Profile of Kevin Petrie in Printmaking Today Winter 2024
No full textKevin Petrie, Professor of Creative Practice at the University of Sunderland, uses print to explore the novels and philosophy of Iris Murdoch writes Dr Miles Leeson. This is a 1200 word profile of Kevin Petrie and his recent work for 'Printmaking Today' which is the journal of the Royal Society of Painter Printmakers. The piece gives an overview of Petrie's creative practice focusing on the novels and thinking of Dame Iris Murdoch (1919-1999). The piece discusses Petrie's evolving model of creative practice for this project: reading the novels, sketching to visualise elements, developing and combining images in the studio and then reengagement with Murdoch (through the community, literature and archive). Petrie's 'Other Journeys' and 'Web of Life' exhibitions are discussed.
The author, Dr Miles Leeson, is the Director of the Iris Murdoch Research Centre at University of Chichester and Visiting Research Fellow at Kingston University. He is the lead editor of the Iris Murdoch Review, the Series Editor of ‘Iris Murdoch Today’ with Palgrave Macmillan, and has published widely on Murdoch’s work. He published Iris Murdoch: Philosophical Novelist (Continuum) in 2010, the edited collection Incest in Contemporary Literature (Manchester University Press, 2018), the festschrift Iris Murdoch: A Centenary Celebration (Sabrestorm Fiction, 2019), the edited collection Iris Murdoch and the Literary Imagination (Palgrave Macmillan, 2022) and is currently writing Iris Murdoch: Feminist.
