Use Of Hearing Protection In Neonatal Intensive Care Unit Patients: A Systematic Review Of The Evidence, Nathalie Chouery, Kathleen T. Dunckley

Journal of Early Hearing Detection and Intervention

Neonatal intensive care unit (NICU) settings present neonates with many environmental hazards, including exposure to dangerous sound intensity levels. Noise levels in NICUs worldwide overwhelmingly exceed the recommendations for safe exposure by the American Academy of Pediatrics. Environmental modifications and staff behavioral changes have proved ineffective to sufficiently reduce infant noise exposure. A systematic review of the literature was undertaken to answer if earmuffs improves physiologic stability, behavioral response, and sleep behavior, which are markers of stress response in NICU patients. Seven databases were searched for pertinent records using a specific search protocol. Seven studies met the review’s inclusion criteria …

The Noise Susceptibility Of Various Speech Bands, Sarah E. Yoho Leopold, Frédéric Apoux, Eric W. Healy

Communicative Disorders and Deaf Education Faculty Publications

The degrading influence of noise on various critical bands of speech was assessed. A modified version of the compound method [Apoux and Healy (2012) J. Acoust. Soc. Am. 132, 1078–1087] was employed to establish this noise susceptibility for each speech band. Noise was added to the target speech band at various signal-to-noise ratios to determine the amount of noise required to reduce the contribution of that band by 50%. It was found that noise susceptibility is not equal across the speech spectrum, as is commonly assumed and incorporated into modern indexes. Instead, the signal-to-noise ratio required to equivalently impact …

Wind Noise: Its Effect On Human Audition, William Roy Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An examination was made of the acoustic characteristics of wind turbulence generated noise in a car traveling at 70 mph over smoothly paved highway with the driver's window down. The overall noise level was found to be at 112 dB SPL with the predominance of energy in the low frequencies. The study was concerned with the effects of such noise on human audition in terms of temporary threshold shift.

Twenty normal hearing young adults were exposed to a tape recording of wind noise for 15 minutes. Post-exposure auditory thresholds at seven discreet frequencies were compared to pre-exposure auditory thresholds at …
