Abstract
A masking sound outputting device includes: an inputting unit which receives a picked-up sound signal relating to a picked-up sound; an extracting unit which extracts an acoustic feature amount of the picked-up sound signal; an instruction receiving unit which receives instructions for starting an output of a masking sound; and an outputting unit which, in the case where the instruction receiving unit receives the instructions for starting an output, outputs a masking sound corresponding to the acoustic feature amount extracted by the extracting unit.
Claims20
A masking sound outputting device comprising:
- an inputting unit adapted to input a picked-up sound signal relating to a picked-up sound;
- an extracting unit adapted to extract an acoustic feature amount of the picked-up sound signal;
- an instruction receiving unit adapted to receive an instruction for starting an output of a masking sound;
- and
- an outputting unit adapted to, when the instruction receiving unit receives the instruction for starting an output, output a masking sound corresponding to the acoustic feature amount extracted by the extracting unit.
The masking sound outputting device according to claim, further comprising:
- a disturbance sound producing unit adapted to, in accordance with the acoustic feature amount extracted by the extracting unit, process the picked-up sound signal to produce a disturbance sound which disturbs a sound to be masked,
- wherein the masking sound output from the outputting unit contains the disturbance sound produced by the disturbance sound producing unit.
A masking sound outputting method comprising:
- an inputting step of inputting a picked-up sound signal relating to a picked-up sound;
- an extracting step of extracting an acoustic feature amount of the picked-up sound signal;
- an instruction receiving step of receiving an instruction for starting an output of a masking sound;
- and
- an outputting step of, when the instruction for starting an output is received in the instruction receiving step, outputting a masking sound corresponding to the acoustic feature amount extracted in the extracting step.
