“…Air conduction (0.25, 0.50, 1, 2, 4 and 8 kHz) and bone conduction (0.5 and 4 kHz, due to limited time) were measured for both ears. Masking was done according to the method of Hood [1960]. Bone conduction thresholds at 4 kHz were +10 dB adjusted afterwards [Margolis et al, 2013].…”

We quantified changes in the auditory acuity of 675 aging adults (mean age 71.1 years, 52.0% female, mean follow-up 4.4 years ± 0.2) of an ongoing cohort study with a pure-tone audiogram and a speech-in-noise test. Generalized estimating equation models were used to study the association between hearing loss and the progression with age, sex, education, cognition, BMI, blood pressure, having type 2 diabetes mellitus, cholesterol ratio, smoking and alcohol consumption. The mean progression of hearing loss was 0.29 and 1.35 dB/year (low and high frequencies). Progression of hearing loss was associated with baseline hearing thresholds. Besides, the presence of type 2 diabetes, smoking, age, sex and time were associated with worse hearing at baseline, but there was no statistical evidence that the tested determinants were associated with progression of hearing loss. This finding indicates that the 4-year progression of hearing loss in older adults in this study is not influenced by the measured determinants. More research with multiple follow-up rounds is desired.

“…During testing, the contralateral ear was masked according to the guidelines of Hood [10], and only thresholds that were reliably masked were included in the analysis. Reliability was determined by two criteria: (1) effective masking of three points at plateau, beginning with minimum masking levels of 5 and 10 dB for each threshold; (2) maximum masking used for the plateau did not exceed the maximum output of the narrow band.…”

Cochlear implantation is associated with deterioration in hearing. Despite the fact that the damage is presumed to be of sensory origin, residual hearing is usually assessed by air-conduction thresholds alone. This study sought to determine if surgery may cause changes in air- and bone-conduction thresholds producing a mixed-type hearing loss. The sample included 18 patients (mean age 37 years) with an air-bone gap of 10 dB over three consecutive frequencies and measurable masked and reliable bone-conduction thresholds of operated and non-operated ears who underwent cochlear implant surgery. All underwent comprehensive audiologic and otologic assessment and imaging before and after surgery. The air-bone gap in the treated ears was 17-41 dB preoperatively and 13-59 dB postoperatively over 250-4,000 Hz. Air-conduction thresholds in the treated ears significantly deteriorated after surgery, by a mean of 10-21 dB. Bone-conduction levels deteriorated nonsignificantly by 0.8-7.5 dB. The findings indicate that the increase in air-conduction threshold after cochlear implantation accounts for most of the postoperative increase in the air-bone gap. Changes in the mechanics of the inner ear may play an important role. Further studies in larger samples including objective measures of inner ear mechanics may add information on the source of the air-bone gap.

“…For example, audiometry can identify an air-bone gap in hearing thresholds, the hallmark of CHL, but not the cause of the hearing loss. 2 Tympanometry can measure the compliance of the whole eardrum and middle ear complex but does not provide specific information about the ossicular chain. 3 A normal tympanogram does not rule out an ossicular problem, and an abnormal tympanogram does not rule it in.…”
