Parameter selection for segregating speech from background noise

Business/Education/Speech and Hearing Science: 1st Place (The Ohio State University Denman Undergraduate Research Forum)Understanding speech in background noise remains a primary challenge faced by hearing-impaired listeners. Ideal binary masking (IBM) is an effective technique to facilitate understanding of a target signal in noisy backgrounds, and IBM estimation is the goal of an effective speech-from-noise separation algorithm that holds promise for alleviating limitations of hearing impairment. In IBM processing, a speech-and-noise mixture is divided into a grid of time-frequency (T-F) units, which are discarded if their degree of noise corruption (reflected as a signal-to-noise ratio, or SNR) exceeds a certain local criterion (LC). Prior work determined that the relationship between the overall SNR of the original speech-noise mixture and LC (the relative criterion or RC) was important for determining intelligibility. This work also suggests that there is a wide range of RC values over which performance scores reach maximum. The current study investigates whether these scores reflect a performance ceiling rather than a true maximum. Consonant recognition was tested in normal-hearing listeners using seven different RC values. The background noise was speech-shaped noise. An RC performance function was obtained that did not display the ceiling effect limitations of previous work, suggesting that the optimal RC value may be different from previous estimates. These findings have implications for selections of LC in IBM estimations. They also suggest appropriate parameters for testing the effect of varying LC within a single mask according to specific frequency contributions to overall speech intelligibility. Such developments may contribute to reducing the struggles that hearing-impaired listeners face in noise.Buckeye Language Network Study of Language Variation (SoLV) Undergraduate Research AwardCollege of Arts and Sciences Undergraduate Research ScholarshipAcademic Major: Speech and Hearing Scienc

The perception, understanding and experience of flourishing in young people living with chronic pain: a Q-methodology study

Much research has adopted a deficits-based approach to chronic pain, neglecting the study of flourishing. Using a Q-methodological framework, this study sought to explore how individuals experience, understand and perceive flourishing in the context of young people living with chronic pain. Fifty-four individuals completed a Q-sorting task, indicating their level of agreement and disagreement with 52 statements. Q-analysis generated three factors that represented clear viewpoints of participants: ‘Pain is not a barrier to flourishing’, ‘Adapting to a new life’ and ‘Adopting a positive perspective’. Factors expressed the viewpoints that flexibility is key to enjoying life despite chronic pain, while resilience, management of stressors, acceptance and problem-solving may be required to flourish with chronic pain. Participants’ understanding of flourishing also focused on the appreciation and enjoyment of life and achievements. This study provides a useful contribution towards furthering our understanding of flourishing in young people living with chronic pain

Looking on the bright side: the relationships between flourishing and pain-related outcomes among adolescents with chronic pain

A deficits-based approach to adolescent chronic pain currently dominates the literature, to the exclusion of positive approaches, such as flourishing. Addressing this knowledge gap, this study examined the relationships between flourishing and pain-related outcomes in adolescent chronic pain. Seventy-nine adolescents aged 11 - 24 years were asked to complete self-report measures ofthree domains of flourishing and four pain-related outcomes. Correlation coefficients and four hierarchical linear regression analyses were conducted, controlling for age and gender. Flourishing mental health was associated with, and significantly contributed to explaining, anxiety and depressive symptoms, and social and family functioning impairment. Benefit finding and posttraumatic growth were each associated with social and family functioning impairment, while posttraumatic growth was also associated with anxiety and depressive symptoms. Additionally, benefit finding significantly contributed to explaining pain intensity. Study findings underscore the importance of assessing the relationships between flourishing and pain-related outcomes in adolescents with chronic pain.<br/
