Sound energy absorbance changes in the elderly with presbycusis with normal outer and middle ear

Objective This study aimed to investigate the wideband tympanometry (WBT) findings in the elderly with presbycusis who have normal outer and middle ears according to otoscopic examination and traditional tympanometry, and to determine whether there is a relationship between the middle ear wideband a...

Description
Summary:Objective This study aimed to investigate the wideband tympanometry (WBT) findings in the elderly with presbycusis who have normal outer and middle ears according to otoscopic examination and traditional tympanometry, and to determine whether there is a relationship between the middle ear wideband absorbance value and the pure tone air–bone gap (ABG) observed especially at mid-high frequencies in the elderly. Methods The study included 30 elderly with presbycusis (> 65 years old, presbycusis group) and 30 healthy individuals (control group) between the ages of 18 and 55. Pure tone air conduction and bone conduction thresholds of all participants were determined and WBT was applied to all participants. Resonance frequency (RF), absorbance ratios at peak pressure (PPAR) and ambient pressure (APAR) values were analyzed. Results The RF value of the presbycusis group was lower than the control group ( p
