“…This divergence is consistent with previous reports that showed differences ranging from 8 to 11 dB for temporal integration at 1000 ms ͑Handler and Margolis, 1977;Silman, 1979a, b;Gelfand and Piper, 1981;Wilson, 1981͒. It has been suggested that the difference in the ART for the BBN activator at 1000 ms is related to the slight differences in hearing sensitivity between younger adults with normal-hearing sensitivity and older adults with normal-hearing sensitivity ͑Jerger et al., 1978a. It was therefore assumed that temporal integration for older and younger adults is similar, and any observed differences are related to slight differences in hearing sensitivity rather than age.…”

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.

“…They suggested that the difference in dB between the two reflex thresholds was an indicator of loudness recruitment in ears with presumed sensorineural hearing losses. Following this research, Jerger et al (1974Jerger et al ( , 1978 developed the Sensitivity Prediction with the Acoustic Reflex (SPAR) test in an attempt to determine hearing sensitivity from normal to profound hearing loss. The classification of hearing sensitivity was based on AR thresholds obtained using BBN and pure tones of 0.5, 1, and 2 kHz, and the difference in thresholds between the BBN and pure-tone activators.…”

“…The classification of hearing sensitivity was based on AR thresholds obtained using BBN and pure tones of 0.5, 1, and 2 kHz, and the difference in thresholds between the BBN and pure-tone activators. Using a modified version of the SPAR test, Jerger et al (1978) were more successful in predicting hearing sensitivity in children (under 10 years of age) than in adults. In young children, acoustic reflex prediction methods clearly offer a rapid, objective measure of hearing sensitivity.…”

This study aimed to compare the high frequency (1 kHz) tympanometry (HFT) and acoustic reflex (AR) measures obtained from infants at birth and at 6-7 weeks of age. HFT results and AR thresholds using a 2-kHz tone and broadband noise activators were obtained from 42 healthy full-term neonates (15 boys and 27 girls) at both test sessions, separated by six weeks. The results showed that the mean values of HFT test parameters and AR thresholds obtained at 6-7 weeks were generally greater than those obtained at birth. In particular, the differences in mean values of uncompensated admittance at 200 daPa, uncompensated peak admittance, uncompensated peak susceptance, peak-compensated static admittance, and AR thresholds with a 2 kHz tone and broadband noise were found to be statistically significant. The findings from this study suggest the need to have separate sets of normative HFT and AR data for infants at birth and 6-7 weeks.

“…1), age, and duration and etiology of the hearing disorder, the three groups produced masking patterns which did not differ significantly. Factors such as age and audiogram contour are known to affect the outcome of other physiological and behavioral tests of auditory function such as the auditory brain stem response (Seitz et al, 1980;Jerger and Hall, 1980;Coats and Martin, 1977;Stockard et al, 1979), acoustic stapedial reflexes (Jerger et al, 1978;Gelfand and Piper, 1981;Hall, 1982a,b), and performance on the Synthetic Sentence Identification (SSI) test (Jerger and Hayes, 1977;Hayes, 1981). Why, then, should these factors play so minor a role in the outcome of the present experiment?…”

Previous research with speechlike signals has suggested that upward spread of masking from the first formant (F 1) may interfere with the identification of place of articulation information signaled by changes in the upper formants. This suggestion was tested by presenting two-formant stop consonant--vowel syllables varying along a/ba--/da/--/ga/ continuum to hearing-impaired listeners grouped according to etiological basis of the disorder. The syllables were presented monaurally at 80 dB and 100 dB SPL when formant amplitudes were equal and when F 1 amplitude was reduced by 6, 12, and 18 dB. Noise-on-tone masking patterns were also generated using narrow bands of noise at 80 and 100 dB SPL to assess the extent of upward spread of masking. Upward spread of masking could be demonstrated in both speech and nonspeech tasks, irrespective of the subject's age, audiometric configuration, or etiology of hearing impairment. Attenuation of F 1 had different effects on phonetic identification in different subject groups: While listeners with noise-induced hearing loss showed substantial improvement in identifying place of articulation, upward spread of masking did not consistently account for poor place identification in other types of sensorineural hearing impairment.
