Abstract: An information processing device includes a first acquisition unit that acquires a sound signal outputted from a mic, an acoustic feature detection unit that detects an acoustic feature based on the sound signal, an identification unit that identifies first discomfort condition information corresponding to a first work type of work performed by a user, among one or more pieces of discomfort condition information specifying discomfort conditions using the acoustic feature and corresponding to one or more work types, based on work type information indicating the first work type, and an output judgment unit that judges whether first masking sound should be outputted or not based on the acoustic feature detected by the acoustic feature detection unit and the first discomfort condition information.

Abstract: An information processing device includes a first acquisition unit that acquires biological information on a user, a first judgment execution unit that executes a first judgment on whether a first discomfort condition is satisfied or not based on first discomfort condition information specifying the first discomfort condition and the biological information, a second acquisition unit that acquires a sound signal, an acoustic feature detection unit that detects an acoustic feature based on the sound signal, a second judgment execution unit that executes a second judgment on whether a second discomfort condition is satisfied or not based on second discomfort condition information specifying the second discomfort condition and the acoustic feature, and an output judgment unit that judges whether first masking sound should be outputted or not based on a result of the first judgment and a result of the second judgment.
