We are surrounded by various sounds like the sound of the car, train, rain and all that in our daily life. It might become feelings very relieved, and come to want to prevent our ear unpleasantly at times. Then, it is thought that it is possible to pursue comfort of the specific sound source like an artificial machine noise by evaluating emotion caused by the sound. There are two methods of evaluating emotion. One is the subjective evaluation like the semantic differential method and the other is the objective evaluation method using biological information, such as electroencephalogram and electrocardiogram. And, a latter method is more certain and quantitative. This study establishes the method for quantitatively evaluating the comfort by measuring electroencephalogram. Then, an objective evaluation to an environmental sound is evaluated by this method.
