[Possible incidental factors in the treatment of noise sensitivity]

On the basis of Eysenck's theory, the authors were assuming that a favorable response was likely to be elicited from dysthymic subjects when treated for their noise susceptiveness by means of relaxation techniques, while hystheric subjects were unlikely to be responsive to treatment. The four-session treatment was administered to a noise susceptive volunteers sample. After a pre-, and post-treatment comparison among individual noise susceptiveness curve were drawn, and an analysis was performed on the variables crossing point, it was found out that, contrary to the authors' hypothesis, the highest inciding variance factor on treatment results was the noise annoyance level sample subjects evidenced.
