Loudness Growth

The loudness growth in 1/2-octave bands (LGOB) procedure has been shown previously to provide valid estimates of loudness growth for adults with normal hearing and those with hearing loss (Allen, Hall, & Jeng, 1990), and it has been widely incorporated into fitting strategies for adult hearing aid users by a hearing aid manufacturer. Here, we applied a simple modification of LGOB to children and adults with normal hearing and then compared the loudness growth functions (as obtained from end-point data) between the two age groups. In addition, reliability data obtained within a single session and between test sessions were compared between the two groups. Large differences were observed in the means between the two groups for the lower boundary values, the upper boundary values, and the range between boundaries both within and across all frequencies. The data obtained from children also had greater variance than the adult data. In addition, there was more variability in the data across test sessions for children. Many test-retest differences for children exceeded 10 dB. Adult test-retest differences were generally less than 10 dB. Although the LGOB with the modifications used in this study may be used to measure loudness growth in children, its poor reliability with this age group may limit its clinical use for children with hearing loss. Additional work is needed to explore whether loudness growth measures can be adapted successfully to children and whether these measures contribute worthwhile information for fitting hearing aids to children.

Method Of Paired Comparisons

Children’s subjective judgments of speech clarity using the methods of paired comparisons and category rating were evaluated in this investigation. Eighty children with normal hearing between the ages of 4 and 8 years judged the clarity of sentences that were systematically bandpass-filtered using conditions that increased intelligibility as estimated by the Articulation Index. Subjects were classified into four age groups (4-, 5-, 6-, and 7–8-year age groups) with 20 subjects per group. With use of materials and training methods suitable for children, judgments were obtained via the two psychophysical procedures (10 subjects per age group for each procedure). Results indicated that children 5 years of age and older were able to make reliable clarity judgments using either procedure; however, the method of paired comparisons was more sensitive than category rating in detecting differences between the bandpass-filtered conditions.

Intensity (loudness), frequency (pitch), and duration discrimination were examined in 41 normal-hearing children, aged 4 to 6 years, and 9 adults. A second study retested 25 of the youngest children 12 to 18 months later. Intensity discrimination showed the least improvement with age and was adultlike by age 5 for most of the children. In contrast, frequency and duration discrimination showed highly significant improvement with age, hut remained poorer than adults' discrimination for many 6-year-olds. Large individual differences were observed within alt tasks and age groups.

Objective: Cortical auditory-evoked potentials (CAEPs), an objective measure of human speech encoding in individuals with normal or impaired auditory systems, can be used to assess the outcomes of hearing aids and cochlear implants in infants, or in young children who cannot co-operate for behavioural speech discrimination testing. The current study aimed to determine whether naturally produced speech stimuli /m/, /g/ and /t/ evoke distinct CAEP response patterns that can be reliably recorded and differentiated, based on their spectral information and whether the CAEP could be an electrophysiological measure to differentiate between these speech sounds.Method: CAEPs were recorded from 18 school-aged children with normal hearing, tested in two groups: younger (5 - 7 years) and older children (8 - 12 years). Cortical responses differed in their P1 and N2 latencies and amplitudes in response to /m/, /g/ and /t/ sounds (from low-, mid- and high-frequency regions, respectively). The largest amplitude of the P1 and N2 component was for /g/ and the smallest was for /t/. The P1 latency in both age groups did not show any significant difference between these speech sounds. The N2 latency showed a significant change in the younger group but not in the older group. The N2 latency of the speech sound /g/ was always noted earlier in both groups.Conclusion: This study demonstrates that spectrally different speech sounds are encoded differentially at the cortical level, and evoke distinct CAEP response patterns. CAEP latencies and amplitudes may provide an objective indication that spectrally different speech sounds are encoded differently at the cortical level.

Auditory Steady State Responses

Background and Purpose: Multiple auditory steady-state responses (ASSRs) to stimuli modulated at ˜80 Hz are a promising technique for threshold estimation in infants, but additional data are required. Research Design: We obtained multiple ASSRs to air-conducted (AC) stimuli. Study Sample: There were 54 children in two age groups: >six months (N = 32) and ≤six months (N = 22). All infants had normal hearing by tone-evoked auditory brain stem response. Results: ASSR thresholds, estimated from 50 percent using cumulative percent present distributions, were 36, 30, 24, and 15 dB HL at 500, 1000, 2000, and 4000 Hz, respectively. Most (≥90%) of the infants showed present ASSRs at 49, 45, 36, and 32 dB HL at 500, 1000, 2000, and 4000 Hz, respectively, with no differences in the results of younger versus older infants. When responses were present for all stimuli for both ears, most infants showed all eight responses within five minutes. Compared to ipsilateral responses, ASSRs in the contralateral EEG (electroencephalogram) channel were smaller and often absent. Conclusions: Based upon these data and the literature, normal AC ASSR “screening” levels would be 50, 45, 40, and 40 dB HL at 500, 1000, 2000, and 4000 Hz, respectively. Using the multiple-stimulus ASSR, infants with normal hearing referred for diagnostic electrophysiological threshold assessment can now be quickly confirmed as having normal thresholds for four frequencies in both ears.

Test Retest Reliability

Most measures of auditory sensitivity at extended high frequencies (frequencies greater than 8 kHz) have been obtained from listeners with normal hearing less than 40 years of age. The purpose of this study was (a) to measure thresholds at frequencies above 8 kHz in older listeners who, as a group, have elevated thresholds at lower frequencies, and (b) to assess test-retest reliability, age and gender effects, and the influence of thresholds below 8 kHz. Extended high-frequency (EHF) thresholds were measured for 162 older listeners (60–79 years) using a commercially available high-frequency audiometer, with a frequency range of 8 to 18 kHz and an intensity range of 0 to 110 dB SPL. Thresholds were measured once at the beginning of a 1- to 2-hour test session and then remeasured at the end of the test session. EHF thresholds of older listeners with normal hearing at conventional audiometric frequencies were substantially higher than the thresholds reported for younger listeners with normal hearing by Dreschler and van der Hulst (1987). EHF thresholds of older listeners with hearing loss at conventional audiometric frequencies were further elevated as compared to older listeners with normal hearing. Differences in EHF thresholds between females and males were either not present or were reduced when gender differences in conventional audiometric thresholds were taken into account. No significant differences were seen in thresholds at 8 kHz and higher between the 60- to 69- and 70- to 79-year-old age groups. Results also indicated that thresholds above 8 kHz can be measured in older listeners within a clinically acceptable ±10 dB test-retest range.

Speech Training

Real-time spectrographic displays (SDs) have been used in speech training for more than 30 years with adults and children who have severe and profound hearing impairments. Despite positive outcomes from treatment studies, concerns remain that the complex and abstract nature of spectrograms may make these speech training aids unsuitable for use with children. This investigation examined how well children with normal hearing sensitivity and children with impaired hearing can recognize spectrographic cues for vowels and consonants, and the ages at which these visual cues are distinguished. Sixty children (30 with normal hearing sensitivity, 30 with hearing impairments) in 3 age groups (6–7, 8–9, and 10–11 years) were familiarized with the spectrographic characteristics of selected vowels and consonants. The children were then tested on their ability to select a match for a model spectrogram from among 3 choices. Overall scores indicated that spectrographic cues were recognized with greater-than-chance accuracy by all age groups. Formant contrasts were recognized with greater accuracy than consonant manner contrasts. Children with normal hearing sensitivity and those with hearing impairment performed equally well.

Atopic Child

Fifty-eight consecutive charts of children suffering from mucoid middle ear effusion proven by myringotomy who were followed for two years were reviewed. Half of the group underwent adenoidectomy and the other half, with similar age distribution, had tympanostomy. Only 20.7% of the adenoidectomized children had normal hearing and aerated middle ears during the two-year follow-up, whereas 59% had normal hearing following tympanostomy. Adenoidectomy had no additional beneficial effect on the cure rate obtained by tympanostomy, which proved to be more effective in all age groups, and in the nonallergic child. In the atopic child, however, both modalities yielded similarly poor results.
