Development Of An Elementary School Background Noise, Amanda L. Mccann
Development Of An Elementary School Background Noise, Amanda L. Mccann
Doctoral Dissertations
The deleterious effects of noise on hearing, comprehension, and academic development have been widely studied. In an effort to accurately observe the effects of noise on specific listening environments, researchers have relied on commercially available forms of background noise. However, these commercially available recordings only contain adult speech and background noises associated with adult environments. A commercially available form of background noise that represents the sounds associated with elementary and middle schools are not readily available. Given that much effort has gone into examining the effects of background noise on classroom performance, it would appear prudent that a background noise …

The Effects Of Background Noise On Distortion Product Otoacoustic Emissions And Hearing Screenings, Amy E. Hollowell
Doctoral Dissertations
Hearing screenings are an important tool for identifying children who have, or are at risk for hearing loss in the schools. In light of a body of evidence that demonstrates the effectiveness of objective screening measures, such as otoacoustic emissions (OAEs), the American Speech Language and Hearing Association (ASHA) recommends traditional pure tone audiometric screening as the tool of choice for hearing screenings in the schools. Pure tone audiometric screenings conducted in the schools are problematic for a number of reasons, but the most significant is the presence of background noise which is routinely encountered. The main purpose of the …
The Effects Of Hearing Aid Circuitry And Speech Presentation Level On Acceptance Of Background Noise, Ashley Powers Boynton
The Effects Of Hearing Aid Circuitry And Speech Presentation Level On Acceptance Of Background Noise, Ashley Powers Boynton
Doctoral Dissertations
The present study investigated the effects of hearing aid circuitry and speech presentation level on ANL and hearing in noise in 19 adult, bilateral hearing aid users. The acceptable noise level (ANL) procedure was used to assess acceptance of background noise. Conventional ANLs (i.e., measured at the participant's most comfortable listening level (MCL)) and ANLs at eight fixed speech presentation levels were obtained. Then global ANLs (i.e., ANLs averaged over eight fixed speech presentation levels) and ANL growth (i.e., the slope of the ANL function) were calculated Each measure was obtained in three conditions: unaided, aided with wide dynamic range …
