Embodiment Construction

[0039] Hereinafter, preferred embodiments of the masking sound output device of the present invention will be described with reference to the accompanying drawings. In the masking sound output device of this embodiment, when the user (listener) performs an operation such as turning on a switch, the sound picked up by the microphone is analyzed, and sufficient masking sound according to the analysis result is output. In this embodiment, that is, when the listener selects the sound or timing to be masked, a comfortable ambient space can be formed in which the sound that the listener does not want to hear (including the noise of the air conditioner, the noise from the outside of the room, etc.) is suppressed. masking. Hereinafter, description will be made on the assumption that a listener who does not wish to hear the speaker's voice is a user of the masking sound output device. Alternatively, a speaker who does not want his / her own talking content to be heard by the listener ma...

Abstract

A masking sound output device includes: an input unit for inputting a pickup signal as a picked-up sound; an extraction unit for extracting an acoustic feature quantity of the pickup signal; an instruction receiving unit for receiving an instruction to start outputting a masking sound and an output unit for outputting a masking sound corresponding to the acoustic feature quantity extracted by the extraction unit when the instruction receiving unit receives an instruction to start output.

Description

technical field [0001] The present invention relates to a masking sound output device that outputs a masking sound to mask the sound, and also relates to a masking sound output method for the masking sound output device. Background technique [0002] A masking technique is known in which, in order to create a comfortable ambient space in a construction site or the like, a sound that is uncomfortable to the listener is picked up, and another sound having an acoustic characteristic (such as a frequency characteristic) similar to the sound is output. sound, thereby making uncomfortable sounds almost inaudible. For example, Patent Document 1 discloses a technique in which frequency components of sounds picked up around a listener are analyzed, and a sound that becomes another sound when mixed with ambient sound is generated and then output. The technique of Patent Document 1 can give a listener a comfortable sound different from an uncomfortable sound without reducing the uncom...
