| description | PROBLEM TO BE SOLVED: To provide a technology of preventing deviation of the sound pressure distribution of a masker sound in an acoustic space without giving an unpleasant feeling to a listener.SOLUTION: When reproduction processing units 120A_n and 120B_n read sound data segments of a disturbing sound and environmental sound constituting a masker sound from a disturbing sound storage region 210 and environmental sound storage region 220, respectively, the reproduction processing units discriminate the presence/absence of the periodicity of the disturbing sound and environmental sound on the basis of the sound data segments, and output the sound data segments so as to apply a delay according to the discrimination result.SELECTED DRAWING: Figure 1
【課題】 聴者に不快感を与えることなく、音響空間内におけるマスカ音の音圧分布の偏りを防止する技術を提供する。【解決手段】 再生処理部１２０Ａ＿ｎおよび１２０Ｂ＿ｎは、それぞれ攪乱音記憶領域２１０および環境音記憶領域２２０からマスカ音を構成する攪乱音および環境音の各音データを読み出すと、当該各音データを基に攪乱音および環境音について周期性の有無を判別し、その判別結果に応じた遅延が付与されるように各音データを出力する。【選択図】図１ |
