Sound masking system for office area

Abstract

The invention relates to a sound masking system for an office area, which belongs to the field of sound processing systems. The system comprises a sound receiver arranged on the outer side of a partition plate of a station and a masking sound generator capable of being electrically connected with the sound receiver. The sound receiver comprises a sound acquisition module and a micro-control modulewhich are connected with each other; the sound acquisition module is used for collecting and processing external environment sounds, and the micro-control module receives and stores sound electric signals sent by the sound acquisition module and controls sending of the electric signals. The masking sound generator comprises a signal processing module and a masking sound generation module, the signal processing module is electrically connected with the masking sound generation module, and the signal processing module is used for receiving a sound electric signal sent by the micro-control module; the signal processing module enables the masking sound generation module to generate masking sounds according to the environment acoustoelectric signal. The system has the effect of reducing the influence of noise near the station on workers.

Description

technical field [0001] The present application relates to the field of sound processing systems, in particular to a sound masking system for office areas. Background technique [0002] If an acoustic signal appears with a noise at the same time, it will become weak or completely inaudible, which means that the hearing threshold of the signal is increased. This is the acoustic masking effect, where the acoustic signal masks the noise. The magnitude of the masking effect depends on the frequency relationship between the acoustic signal and the noise. Generally speaking, the closer the frequency of a pure-tone acoustic signal to pure-tone noise, the greater the masking, and the masking of low-frequency sounds to high-frequency sounds is often greater than the masking of high-frequency sounds to low-frequency sounds. A polyphonic noise is usually a combination of multiple frequencies, and there is a fundamental frequency in the frequency combination of the noise. Other frequen...

Problems solved by technology

[0003] At present, in the office area, when the staff is working at their own workstations, the local area of ​​the office may be too noisy, which will not only distract the staff's attention, but also affect their work efficiency

[0004] In view of the above-mentioned related technologies, the inventor believes that there is a defect that the environment in the office area is noisy and affects office efficiency
