Abstract : The standard frequency spectra for the Chinese language was determined, using mean frequency spectra. The mean frequency spectra were modified by smoothing the lower band and by replacing the hf band (800 cps or higher for male sounds and 1000 cps or higher for female sounds) by a straight line with a slope of 12 db/'multiple frequency range.' Total sound intensities were determined by a summation process and converted into sound pressure levels. A sound pressure level of 69 db at one meter from a speaker's lips was considered the standard condition. It is concluded that an error of less than 2 db results from comparison between the standard and actual frequency spectra. (Author)
