“…This is in accordance with the study conducted by Gates et al and Sogebi. 24,25 On contrary, gender differences were seen as higher ear canal volume in males when compared to females. 7,26 But in the current study, only compliance measure was taken into consideration while categorizing into Jerger's type of tympanograms classification.…”

Background: Tympanometry is a non-invasive test clinical test for the assessment of middle ear status/functioning. Several studies over the past few years have produced conflicting results regarding changes in the middle ear function with advancing age. Hence, the present study is aimed to give evidences on distributions of type of tympanograms in males and females under various age groups.Methods: The study followed retrospective design, where data collected from January 2017 to October 2017 were used. A total of 2,292 tympanograms of the 1146 patients were analysed. Descriptive statistics and Wilcoxon’s signed rank test were used. A p-value <0.05 was considered as significant. Results: It was documented that higher occurrence of ‘B’ type and ‘Ad’ type of tympanogram in paediatric group and geriatric group respectively. As it is expected, ‘A’ type of tympanogram is predominant in adult and older adult group. Also, there was no gender difference seen in type of tympanograms.Conclusions: Higher occurrence of ‘B’ type of tympanogram in paediatric group warrants medical line of treatment and educating on ear-hygiene in them.

“…Consequently, both conductive and sensorineural hearing loss and central auditory processing disorder can be observed in age-related hearing loss (11). Thus, it is critical to evaluate the external, middle, and inner ear as well as central auditory processing to enable proper diagnosis and management in elderly people (10,12).…”

The global population is gradually aging both domestically and abroad. Aging leads to a variety of anatomical and physiological changes occur in the auditory system. These changes cause hearing impairments that are called "age-related hearing loss.” Age-related hearing loss is a common chronic health condition that affects quality of life. There is no intervention available that prevents age-related hearing loss. However, there are intervention options that can improve daily life functions and well-being as well as decrease or compensate the negative effects of hearing loss. Thus, the importance of studies about age-related hearing loss has been progressively increasing.

“…The mechanical properties of the middle ear change with age (Ruah et al, 1991) and could explain some age-related hearing loss (Corso, 1992, Rosenhall et al, 1990). Elderly humans with abnormal tympanometry are ∼50% more likely to have age-related hearing loss (Sogebi, 2015) and middle ear admittance (compliance) tends to decrease from the age of 20 to 40 (Wada et al, 1993). A consistent finding is no further changes in middle ear properties after the age of 40.…”

Insect cuticle is an evolutionary-malleable exoskeleton that has specialised for various functions. Insects that detect the pressure component of sound bear specialised sound-capturing tympani evolved from cuticular thinning. Whilst the outer layer of insect cuticle is composed of non-living chitin, its mechanical properties change during development and aging. Here, we measured the displacements of the tympanum of the desert Locust, Schistocerca gregaria, to understand biomechanical changes as a function of age and noise-exposure. We found that the stiffness of the tympanum decreases within 12 hours of noise-exposure and increases as a function of age, independent of noise-exposure. Noise-induced changes were dynamic with an increased tympanum displacement to sound within 12 hours post noise-exposure. Within 24 hours, however, the tone-evoked displacement of the tympanum decreased below that of control Locusts. After 48 hours, the tone-evoked displacement of the tympanum was not significantly different to Locusts not exposed to noise. Tympanal displacements reduced predictably with age and repeatably noise-exposed Locusts (every three days) did not differ from their non-noise-exposed counterparts. Changes in the biomechanics of the tympanum may explain an age-dependent decrease in auditory detection in tympanal insects.

Middle ear impedance studies in elderly patients implications on age-related hearing loss

Abstract: Some abnormalities were observed in the impedance audiometric measures of elderly patients, which were significantly associated with parameters connected to age-related hearing loss.
