“…However, when Margolis and Heller's (1987) data were compared with Wiley et al's (1996) data obtained from adults aged 48 to 92 years, the participants in Margolis and Heller's (1987) study had significantly greater Ytm, smaller ear canal volume (Vea) and larger tympanometric Wideband Energy Absorbance in Adults width (TW). In another study, Roup et al (1998) found that their participants, aged 20 to 30 years, had significantly higher Vea and smaller TW than the participants in Margolis and Heller's (1987) study. Nevertheless, these differences in 226-Hz tympanometric parameters across age groups between studies do not provide sufficient evidence of an age effect on the outer and middle ear because of the differences in subject samples, equipment and experimental design.…”

Abbreviations: EAwere assessed. Energy absorbance (EA) data were collected at 30 frequencies using a prototype commercial instrument developed by Interacoustics. Results: Results showed that young adults had significantly lower EA from 400 Hz to 560 Hz than the middle-aged group. However, the middle-age group showed significantly lower EA between 2240 Hz and 5040 Hz than the young adult group. Additionally, the elderly had significantly lower EA than the young adult group between 2520 to 5040 Hz. No significance difference in EA was found at any frequency between middle-aged and older adults. Across age groups, gender differences were found with males having significantly higher EA values than females at lower frequencies, whereas females had significantly higher EA at higher frequencies. Conclusions: This study has provided evidence of the influence of gender and age on EA in adults with normal outer and middle ear function. These findings support the importance of establishing age-and gender-specific EA norms for the adult population. Wideband Energy Absorbance in Adults

“…Tympanometry was performed in test ears (Interacoustics Audio Traveler AA220, Interacoustics, Assens, Denmark). All subjects had normal equivalent ear canal volume, peak pressure, and compliance (Roup et al, 1998). Subjects were chosen to form pairs based on similarity in hearing thresholds near the SOAE frequency of the SOAEþ subject.…”

Hearing thresholds have been shown to exhibit periodic minima and maxima, a pattern known as threshold microstructure. Microstructure has previously been linked to spontaneous otoacoustic emissions (SOAEs) and normal cochlear function. However, SOAEs at high frequencies (>4 kHz) have been associated with hearing loss or cochlear pathology in some reports. Microstructure would not be expected near these high-frequency SOAEs. Psychophysical tuning curves (PTCs), the expression of frequency selectivity, may also be altered by SOAEs. Prior comparisons of tuning between ears with and without SOAEs demonstrated sharper tuning in ears with emissions. Here, threshold microstructure and PTCs were compared at SOAE frequencies ranging between 1.2 and 13.9 kHz using subjects without SOAEs as controls. Results indicate: (1) Threshold microstructure is observable in the vicinity of SOAEs of all frequencies; (2) PTCs are influenced by SOAEs, resulting in shifted tuning curve tips, multiple tips, or inversion. High frequency SOAEs show a greater effect on PTC morphology. The influence of most SOAEs at high frequencies on threshold microstructure and PTCs is consistent with those at lower frequencies, suggesting that high-frequency SOAEs reflect the same cochlear processes that lead to SOAEs at lower frequencies.

“…The aim of the present study was to develop the open-set Turkish Monosyllabic Word Recognition Test (TMWRT) for adults. , and they had pure-tone air conduction thresholds of less than 10 dB HL at all octave frequencies from 250 to 8000 Hz and static acoustic admittance between 0.3 and 1.4 mmhos, with peak pressure between -100 and +50 daPa [24,25] . For each subject, the ear with the better pure-tone average thresholds at 500 Hz, 1000 Hz, and 2000 Hz was selected as the test ear.…”

OBJECTIVE:The aim of this study was to develop a Turkish-specific speech recognition test, considering phonemic balance, homogeneity, and familiarity criteria. MATERIALS and METHODS:The most frequently used Turkish monosyllabic words were selected from the corpus. Thirty-six young adults with normal hearing were divided into two groups and asked to listen to words from the word pool; the words were given twice at six different intensity levels. The least and most frequently known words were identified and eliminated in order to provide homogeneity. Three word lists, each composed of 50 phonemically balanced words, were developed to be used in the tests. These lists were divided into two according to the phonemic balance criteria. RESULTS:No statistically significant difference was found among the word lists. Furthermore, the internal reliability of each list was analyzed using KR-20 and was found to be above 98% for all lists. CONCLUSION:The lists derived from the Turkish language were ascertained to be appropriate for use. As a result of using the developed lists to test individuals with various auditory pathologies, it will be possible to assess the lists' capability to distinguish pathological cases according to the location of the pathology.
