Abstract
A few reports on the interference with radio or television listening were presented by means of the social surveys, but there are few investigations on noise evaluation in broadcast listening. This study aimed at obtaining the noise evaluation in broadcast listening and the relation between annoyance of noise and physical parameters such as types of noise, noise level, average frequency of occurrences, and so on. Three types of noise; steady noise, intermittent noise, and impulsive noise, were used in the experiment. Broadcast program was the reading of novels and music. The results showed that the annoyance of the steady noise, the intermittent noise and the impulsive noise was almost determined by Leq in broadcast listening. Investigated in detail, however, the results showed that the steady noise was the most annoying, the intermittent was the next, and the impulsive was the least annoying.
