Embodiment

[0030] The present invention collects audio information through an audio collection device, the set-top box receives the collected audio information, and classifies the collected audio information through audio analysis software, for example, separating horn sounds, traffic sounds, and the like. The collected audio information is displayed on the display. Through the remote control of the set-top box, the user can audition and operate the audio content to determine which types of audio belong to noise and need to be blocked. After the set-top box receives the remote control to determine the type of sound that needs to be shielded, the audio signal is processed by inverse phase technology to generate a corresponding noise-suppressed audio signal, which is sent to the noise-cancellation device. The noise canceling device plays the sound at the corresponding frequency according to the audio signal sent by the set-top box. This sound neutralizes outside noise for noise reduction. ...

Abstract

The invention provides a noise eliminating method based on intelligent home furnishing and a system thereof. The method comprises the following steps: (1) collecting all audio information in a residential environment, (2) classifying the collected audio information according to the frequency and displaying the information to a user, (3) receiving a shielding command of the user and setting a type selected by the user as audio needed to be shielded, and (4) generating an audio signal whose phase is opposite to that of the audio which is needed to be shielded and playing the audio signal to neutralize environmental noise. According to the method and the system, a user selection function is added on the basis of active noise reduction, thus the shielding of natural sound and alarm sound can be prevented, and the healthy life of people can be ensured to a certain extent.

Description

technical field [0001] The invention relates to the field of smart home, in particular to a method and system for eliminating noise based on smart home. Background technique [0002] The prosperity of the economy and the rapid growth of GDP. The tide-like crowd, the public's crazy pursuit of efficiency, harsh sounds one after another, the sound of traffic, horns, mechanical roars, the noise of the public, advertisements in shopping malls, and the noise and disputes outside the window that destroy you from time to time. All kinds of noise constitute the melody of today's urban life. Can urban life reduce those annoying noises while bringing convenience to the public? [0003] With the development of the smart home industry, more resources have been devoted to solving the noise pollution in public family life. There are currently two main ways to reduce noise, one is passive noise reduction, and the other is active noise reduction. Passive noise reduction reduces noise thr...
