Abstract: An object of the present invention is to stably and efficiently provide an oxidized cellulose having excellent fibrillatability. The above object can be achieved by a method of producing an oxidized cellulose, which contains an oxide of a cellulose raw material by a hypochlorous acid or a salt thereof, is substantially free of N-oxyl compounds, and has a degree of polymerization of 600 or less, the method including a step of obtaining an oxidized cellulose by oxidizing a cellulose raw material using a hypochlorous acid or a salt thereof, wherein viscosity of a slurry of the cellulose raw material having the same concentration as when the oxidation is performed is in a range of 1,000 Pa·s or less at 30° C. or 40° C.

Abstract: The present invention provides a sound image position correction system that applies sound image position correction processing to a voice signal so that an optimal sound image position is obtained. There is provided a sound image position correction system which corrects the position of a sound image output from a plurality of speakers in a multichannel reproduction system having three or more channels, which includes a speaker moving section that moves the positions of the plurality of speakers provided in the multichannel reproduction system, a speaker position detection section that detects the positions of the plurality of speakers moved by the speaker moving section, and a sound image position correction section that applies sound image position correction processing to a sound signal to be supplied to the plurality of speakers based on the positions of the speakers detected by the speaker position detection section.
