Abstract

The invention provides an array type auditory masking device, comprising: the main control platform (10) of an accessing interface platform (20) and a plurality of user platforms (30). In the main control platform, a storage device (14) outputs voice interfering signals based on the language choice instruction transmitted by an operation unit (12). A first signal processing unit (16) arbitrarily combines the voice interfering signals and generates a first masking signal. A control unit starts the user platforms according to the user platform choosing instruction outputted by the operation unit. Each user platform comprises a voice acquiring unit (34), a second signal processing unit (36), a sound receiving unit (32) and an audio playing unit (38). The second signal processing unit is in signal connection with the other devices of the user platform as well as the interface platform and segments the voice signals outputted by the voice acquiring unit and arbitrarily combines them into a second masking signal. Based on the first masking signal and the second masking signal, the audio playing unit plays the first masking sound and the second masking sound.

Description

technical field [0001] The invention relates to a sound masker, in particular to an array type sound masker. The invention also provides a sound masking method. Background technique [0002] In language conversations, there are often private content that you don't want others to know or don't want others to record and collect evidence during the conversation. Existing methods are often realized by shielding transmission signals, pre-discovering or partial signal interference to other people's recording, eavesdropping and other equipment, but it cannot prevent others from directly understanding the conversation, and there will be some signal interference to recording, eavesdropping and other equipment. In the case of failure, and in the meeting, the signal interference to the recording, eavesdropping and other equipment often affects the normal operation of the equipment used in the meeting. Contents of the invention [0003] The object of the present invention is to prov...
