【正文】 one of lower frequency.[14] In 1959, Richard Ehmer described a plete set of auditory curves regarding this phenomenon.[15] Ernst Terhardt et al. created an algorithm describing auditory masking with high accuracy.[16] This work added to a variety of reports from authors dating back to Fletcher, and to the work that initially determined critical ratios and critical bandwidths. 樣例文本 B ? The MP3 lossy audio data pression algorithm takes advantage of a perceptual limitation of human hearing called auditory masking. In 1894, Alfred Marshall Mayer reported that a tone could be rendered inaudible by another tone of lower frequency.[14] In 1959, Richard Ehmer described a plete set of auditory curves regarding this phenomenon.[15] Ernst Terhardt et al. created an algorithm describing auditory masking with high accuracy.[16] This work added to a variety of reports from authors dating back to Fletcher, and
