“…The gender effect demonstrated in the present study is consistent with Feeney and Sanford (2004) who reported significant gender differences with females having lower EA (higher ER) than males at 794 and 1000 Hz, but higher EA (lower ER) at 5040 Hz. Carpenter et al (2012) also found significant gender related differences in EA from 1007 to 1265 Hz and from 3000 to 5039 Hz. Shahnaz and Bork (2006) suggested that difference in EA between males and females may be attributed to differences in both middle ear and ear canal volume due to difference in body size between the two genders.…”

“…Although Rosowski et al (2012) reported that ER measured from females were generally higher than males at frequencies ≤2000 Hz and lower from 3000 to 6000 Hz, only ER at 4000 Hz was found to be statistically significant with gender. Besides the two aforementioned studies, gender differences have also been reported by Carpenter et al (2012 Table 1.…”

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

“…The wideband tympanometry technique is more sensitive and specific than standard clinical testing to many conductive disorders including OME, since it measures the full range of frequencies important for speech perception (Hunter, Prieve, Kei, & Sanford, 2013). This technique has also been used to interpret high frequency hearing thresholds (Margolis et al, 2000) and cochlear measures with respect to possible middle ear effects (Carpenter, Cacace, & Mahoney, 2012).…”

Objectives: This study tested the hypothesis that undetected peripheral hearing impairment occurs in children with idiopathic listening difficulties (LiD), as reported by caregivers using the Evaluation of Children's Listening and Processing Skills (ECLiPS) validated questionnaire, compared to children with typically developed (TD) listening abilities.Design: Children with LiD aged 6-14 y.o. (n = 60, mean age = 9.9 yr.) were recruited from audiology clinical records and from IRB-approved advertisements at hospital locations and in the local and regional area. Both groups completed standard and extended high frequency pure tone audiometry, wideband absorbance tympanometry and middle ear muscle reflexes, distortion product and chirp transient evoked otoacoustic emissions. Univariate and multivariate mixed models and multiple regression analysis were used to examine group differences and continuous performance, as well as the influence of demographic factors and pressure equalization (PE) tube history.Results: There were no significant group differences between the LiD and TD groups for any of the auditory measures tested. However, analyses across all children showed that extended high frequency hearing thresholds, wideband tympanometry, contralateral middle ear muscle reflexes, distortion product and transient evoked otoacoustic emissions were related to a history of PE tube surgery. The physiologic measures were also associated with extended high frequency hearing loss, secondary to PE tube history. Conclusions:Overall, the results of this study in a sample of children with validated LiD compared to a TD group matched for age and sex showed no significant differences in peripheral function using highly sensitive auditory measures. Histories of PE tube surgery were 4 73 significantly related to EHF hearing and to a range of physiologic measures in the combined 74 sample.

“…Moreover, there are assertions that malfunctions of the middle ear affects inner ear functioning. For instance, middle ear measurements by broadband middle ear power reflectance (BMEPR) suggested middle ear transmission characteristics played a role in active physiologic process within the inner ear, measured by spontaneous otoacoustic emissions (SPOAEs) 11 . Similarly, Uchida et al confirmed that the condition of the middle ear function measured by tympanometry affects the functioning of the cochlear measured by distortion-product otoacoustic emissions (DPOAEs) 12 It is thus important that middle ear dynamics and functioning be assessed in order to effectively manage other forms of hearing impairment in elderly subjects.…”

BackgroundLittle is known about functioning of the middle ear with advancing age.ObjectivesTo estimate the prevalence and describe tympanometric patterns of sub-clinical middle ear malfunctions,( S-MEM) in elderly patients. It also assessed clinical factors that could predict S-MEM.MethodsCross-sectional, analytical study of patients aged ≥ 60 years in a tertiary hospital in Nigeria between 2011–2014. Pure tone audiometry (PTA), tympanometry and acoustic reflexes were recorded. S-MEM was based on audiometric and tympanometric evident abnormalities. Descriptive, univariate and multivariate analyses performed to detect independent clinical predictors of S-MEM at p-value of <0.05.Results121 patients , M: F of 1.1:1. Mean age was 70.1 ± 6.2 years, 77.7% were married. Prevalence of S-MEM was 21.5%. Abnormal tympanometric tracings were type AS>C>B>AD. The parameters that were statistically-significant on univariate analyses were subjected to logistic regression analysis which confirmed previous head injury, diabetes, osteoarthritis of knee joint, and absent acoustic reflex as clinical predictors for S-MEM.Conclusion21.5% of elderly Africans had subclinical abnormalities in their middle ear functioning, mostly with type AS tympanogram. Independent clinical predictors of S-MEM included previous head injury, diabetes, history of osteoarthritis of knee joints, and absent acoustic reflex.
