Abstract: In this study the researchers examined the ability of 40 young children (ages 5-8) to understand speech (monosyllables, spondees, trochees, and trisyllables) when listening in a background of real life classroom noise. The findings include the following: all children had some difficulty understanding speech when the noise was at levels found in many classrooms (i.e., 65 dBA), but, at an intermediate (-6 dB SNR) level; kindergarten and grade 1 children had much more difficulty than did older children. Conversely, all children performed well in quiet, with results being comparable to or slightly better than those reported in previous studies. According to the research team, these results indicate that the youngest children in the school system, whose classrooms also tend to be among the noisiest, are the most susceptible to the effects of noise.

Recording Auditory Steady-State Responses in Young
Author(s): John, M. S., Brown, D. K., Muir, P. J., Picton, T. W. Source: Ear and Hearing: Journal of The American Auditory Society. 25(6): 539-53. December 2004.

Abstract: A summary of a study that examines the auditory steady-state responses (ASSRs) evoked by amplitude-modulated (AM), mixed- modulated (MM), and exponentially-modulated (AM2) tones in 50 newborn infants, within 3 days of birth, and in 20 older infants, within 3-15 weeks of birth. Multiple ASSRs were evoked by 0.5, 1, 2, and 4 kHz stimuli modulated between 78 and 95 Hz and presented at 50 dB SPL. The report details results for both newborn and older infants and findings that indicate the following: using MM and AM2 stimuli will increase the reliability/efficiency of evoked potential audiometry in infancy; ASSRs at 50 dB SPL are more easily detected at 3-15 wk of age than just after birth; comprehensive frequency-specific testing of hearing using steady-state responses will likely be more accurate if postponed until after the immediate neonatal period.

firstname.lastname@example.org. Website: http://www.nrharural.org/. Language: English. Abstract: This report presents details about a study conducted to compare the prevalence pf physiological hearing loss among older adults by nonmetro/metro residence and the successes of hearing aid use in these circumstances. The study analyzes 8,222 respondents to Wave 1 (1993-1994) of the national Asset and Health Dynamics Among the Oldest Old (AHEAD) Survey. Some findings show that: nonmetro residents had the same odds as metro residents of having no residual hearing loss when a hearing aid was worn (versus having physiologically normal hearing); the risk for nonmetro residents was much greater than their metro counterparts for having a hearing loss but no hearing aid or a residual hearing loss even when wearing a hearing aid. The status of either of these occurrences was greater by association than by age. The authors conclude that future studies should add nonmetro residence to the list of risk factors for negative hearing outcomes, especially since the percentage of elderly nonmetro residents is likely to grow over the next twenty years.

Abstract: In this chapter of the fourth edition of Auditory Disorders in School Children the author discusses approaches to the assessment of auditory processing amid the identification of children with auditory processing disorders (APDs). Over the years the term 'auditory processing disorders' has evolved and is variously described as a central auditory processing disorder (CAPD), auditory perceptual disorder, auditory language-learning disorder, and auditory processing disorder (APD). APD is the term the author uses in this chapter. Subject Category: Hearing. Speech.
