发明名称 Masker sound generation apparatus and program
摘要 In a masker sound generation apparatus, an acquisition part acquires a sound signal, and a generation part generates a masker sound signal based on the acquired sound signal. Specifically, the generation part divides the sound signal acquired by the acquisition part into a plurality of sections each having a predetermined time length, then repeats a sorting process of sorting the divided sections as a process of changing the sequence of arrangement of the sound signal, and alters a manner of sorting the sections each time the sorting process is repeated.

主权项 1. A masker sound generation apparatus comprising: an acquisition part that acquires a sound signal having a first predetermined time length; and a generation part that repeats, for a second predetermined time length longer than the first predetermined time length, a process of outputting a masker sound signal obtained by changing a sequence of arrangement of the sound signal of the first predetermined time length according to a random number sequence, and that repeats a process of altering the random number sequence each time the second predetermined time length passes.
