Embodiment Construction

[0075] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0076] The noise reduction method for household appliances provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the home appliance 102 communicates with the server 104 through a network. When a noise signal is detected on the household electrical appliance 102, the noise signal is collected. By acquiring a preset initial reference noise signal, and according to the initial reference noise signal, a secondary sound source signal opposite in phase to the initial reference noise signal is determined. Wherein, the pr...

Abstract

The invention relates to a household appliance noise reduction method and a device, computer equipment and a storage medium. The method comprises the following steps: when a noise signal is detected on the household appliance, collecting the noise signal; obtaining a preset initial reference noise signal, and determining a secondary sound source signal opposite to the initial reference noise signal in phase; when it is determined that the noise signal needs to be denoised according to the secondary sound source signal, performing weighting processing on the noise signal and the secondary soundsource signal; superposing the weighted noise signal and the secondary sound source signal to obtain an error signal; correcting the secondary sound source signal according to the error signal to obtain a corrected secondary sound source signal; and performing noise reduction processing on the noise signal according to the corrected secondary sound source signal. By adopting the method to correctthe reverse noise of the household appliance, the uncertainty of the original noise is effectively adapted, the noise reduction effect for the household appliance is improved, the original performance of the household appliance is ensured, and the noise reduction processing working efficiency for the household appliance is improved.

Description

technical field [0001] The present application relates to the technical field of electric appliance control, and in particular to a noise reduction method, device, computer equipment and storage medium for household appliances. Background technique [0002] With the development of electrical control technology and the improvement of people's living standards, the requirements for quality of life are also increasing. All kinds of household appliances will inevitably produce a certain amount of noise during the use of daily life, which becomes an important factor affecting people's quality of life, and excessive noise affects people's quality of life and health. The noise generated by electrical appliances, such as range hoods, washing machines, etc., is reduced during use. [0003] The traditional noise reduction methods for home appliances, such as range hoods, mostly use the method of directly setting low air volume to reduce noise. However, the traditional method of redu...
