Horowitz G, et al. - In this investigation involving 20 healthy volunteers (ages ranged from 20 to 30 years), researchers analyzed the possible interference of simulated conductive hearing loss with the ability to maintain postural balance. Study participants had computerized dynamic posturography test battery before and after plugging their external ear canals with earplugs thus simulating a 40dB conductive hearing loss. Participants were tested before and after plugging their ear canals. Data reported that the average conductive hearing loss was 40 ± 4.9dB. Findings suggested that conductive hearing loss affects the balance negatively. The relationship between hearing loss and saccular dysfunction may explain this theoretically.
