“…This is well within the range typically reported for wide band stimuli, such as broadband noise, and is lower than has been observed in response to tonal stimuli (Silman et al, 1987). Summation across frequency is thought to underlie the lower acoustic reflex thresholds for noise than for tones, and is probably also responsible for the lower thresholds resulting from the broadband harmonic complexes used here.…”

“…This type of measurement is a routine part of audiological assessment, assisting in the evaluation of the integrity of the middle ear as well as other structures along the reflex arc involving both the VIIIth nerve (sensory) and VIIth nerve (motor), the cochlea, and some brainstem nuclei. Acoustic reflexes are typically elicited at sound levels from approximately 85-100 dB SPL for tones and about 65-95 dB SPL for broadband noise (BBN) stimuli (Silman et al, 1987). The acoustic reflex threshold, defined as the lowest intensity of a given sound that is sufficient to produce a contraction of the stapedius muscle, is affected by frequency, bandwidth, and duration of a stimulus (Silman and Gelfand, 1982), with generally lower thresholds for long-duration, broadband sounds like noise (Dallos, 1964;Flottorp et al, 1971;Silman et al, 1987).…”

The measurement is fast and non-invasive, and the magnitude of the acoustic reflex measure is related to the intensity of the activating stimulus (Silman et al, 1978;Wilson and McBride, 1978).…”

“…Although aging effects on the acoustic-reflex threshold ͑ART͒ for the tonal activator appear to be absent ͑Osterhammel and Osterhammel, 1979;Silman, 1979a;Gelfand and Piper, 1981;Thompson et al, 1980;Silverman et al, 1983;Silman et al, 1987͒, several studies have shown significantly increased ARTs for the broad-band noise ͑BBN͒ activator in older than younger adults ͑Handler and Margolis, 1977;Silman, 1979a;Gelfand and Piper, 1981;Silverman et al, 1983͒. Jakimetz et al ͑1989͒ investigated the effect of signal bandwidth and spectral density on the ART in the elderly.…”

Although numerous studies have investigated temporal integration of the acoustic-reflex threshold (ART), research is lacking on the effect of age on temporal integration of the ART. Therefore the effect of age on temporal integration of the ART was investigated for a broad-band noise (BBN) activator. Subjects consisted of two groups of adults with normal-hearing sensitivity: one group of 20 young adults (ten males and ten females, ages 18-29 years, with a mean age of 24 years) and one group of 20 older adults (ten males and ten females, ages 59-75 years, with a mean age of 67.5 years). Activating stimulus durations were 12, 25, 50, 100, 200, 300, 500, and 1000 ms. Significant main effects for duration and age were obtained. That is, as the duration increased, the acoustic reflex threshold for BBN decreased. The interactions of duration x age group and duration x hearing level were not significant. The result of pair-wise analysis indicated statistically significant differences between the two age groups at durations of 20 ms and longer. The observed age effect on temporal integration of the ART for the BBN activator is interpreted in relation to senescent changes in the auditory system.

“…Dieroff and Meibner (1989) documented a similar WRS reduction in the unfitted ears of subjects with mixed hearing loss . More recently, investigators illustrated the unaided ear effect with case study reports (Silverman and Silman, 1990 ;Silman et al, 1992 ;Boothroyd, 1993 ;Gelfand, 1995 ;Hurley, 1993 ;Silverman and Emmer, 1993). These reports, along with the data of Burkey and Arkis (1993), indicate that the unaided ear effect in some individuals with SNHL can be reversed with binaural amplification.…”

The purpose of this investigation was to study further the assertion that auditory function deteriorates in the unaided ear of individuals with sensorineural hearing loss (SNHL) who receive monaural hearing aid fittings. The word recognition scores (WRSs) of 77 monaurally and 65 binaurally fitted subjects with symmetric bilateral SNHL were examined at 1, 3, and 5 years post hearing aid fitting. The deterioration in auditory function was defined as a significant change in the WRSs for Northwestern University Auditory Test No. 6 (NU-6) materials in the unaided ear of individuals fitted with a monaural hearing aid arrangement. Analyses of the data indicate that 25 percent of the monaurally fitted subjects experienced a significant change in the WRSs of their unaided ears, whereas only 6 percent of the binaurally fitted subjects experienced a significant change in the WRSs of either ear. Auditory function does deteriorate in the unaided ears of individuals with SNHL who receive monaural hearing aid fittings. Moreover, the decline in auditory function of the unaided ear does not result from a decrease in hearing sensitivity. Abbreviations: NU-6 = Northwestern University Auditory Test No. 6, PTA = pure-tone average, SNHL = sensorineural hearing loss, WRS = word recognition score
