Abstract
In this paper, we evaluated the impression of the composed noise of air exhaust sound and air compressor sound which are typical noises of home medical equipment, in order to examine a method for quantitatively evaluating the uncomfortableness of the noise of home medical equipment. As a result, it was confirmed that there was a high correlation between the subjective evaluation value of uncomfortableness and the loudness and sharpness of the psychoacoustic metrics when only exhaust sound was heard. In addition, it is suggested that the uncomfortableness of the air exhaust noise that can be heard in the complex noise composed of the air compressor sound and the air exhaust sound can be quantitatively estimated from the loudness and sharpness calculated by the masked loudness method.
