Abstract:
Subjective disturbances, due to hearing loss, are auditory disability and handicap which can be evaluated with a questionnaire. The present study refers to a population of industrial workers affected by noise-induced hearing loss. Aim of the study is to identify the minimal level of hearing loss over which the patient felt changes in his quality of life, and the average auditory threshold at which the patient considered the application of a hearing aid useful or necessary. The sample comprised 180 males with noise-induced hearing loss. Each subject received a questionnaire designed for this study. Data show a correlation between disability, handicap and the degree of noise-induced hearing loss. The most relevant problems in noise-induced hearing loss are correlated with disability rather than handicap. 35 dB can be considered as the level above which these devices can be suggested to patients. Hearing aids can become a therapeutic instrument even in the presence of a low degree of hearing loss.

Sound Intensity Level
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and hence a...

Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by identifying...
