The audio analysis of sound reproduction equipment, such as loudspeakers, amplifiers, and so on, is composed of overall measurement (and analysis) of electric signals and acoustic signals. And the subjective listening test has been admitted as being a general measurement method also, because audio test equipment has limits of measurement and the human ear has a superior sensing ability. But the subjective listening test method varies according to personal taste and to the degree of skill for the sound. In addition, it varies according to the person’s mental state. So, there has been argument about the objectivity of it. This paper proposes that sound factors (parameters) should be classified into eight categories according to the specific character of the loudspeakers and the sense of hearing. We manufactured a test reference CD for an estimate.
