Jazz, popular music, is originated from African American music between late 19th century and early 20th century with developments of elements of classic music and marches. This genre of music has attractive sound of saxophone and Jazz recorder with performance orientation such as tap dance and vocal percussion. Swing rhythm is one of distinguish characteristics of Jazz. Because of improvisation and fast rhythm, not everyone loves Jazz. However, many people become a fan of Jazz because of it. Even with the improvisation, Jazz delivers the lyrics clearly to audiences like other types of music. Each genre music has to satisfy some auditory environment for performance. For example, auditory environment for classic music has studied, and many auditoriums for classic music were built for the best auditory stimulation.In our study, an analysis of the energy ratio of frequency division, one of Jazz acoustic characteristics, showed that a low frequency amplifies at a half of its wavelength from the sound source. Each sound has its own frequency. Each frequency has better sound at different distance. Our findings indicate that low frequency amplifies its sounds at a half of its wavelength, and high frequency, including voice frequency, amplifies its sound at the point where its wavelength become 23 times farther from the sound source. This helps audience to hear the lyrics and music more clearly. Based on the result, we suggested the reference of Jazz concert halls, considering auditory condition for Jazz.
