Description

Method and device for detecting and eliminating hum noise by using mobile phone

The invention belongs to the field of noise elimination, and particularly relates to a method and a device for detecting and eliminating hum noise by using a mobile phone, which can detect snoring effectively and perform noise elimination with extremely simple mobile phone tools.

Snoring is a common phenomenon in society. There are many reasons for it, such as age, fatigue, and obesity, which not only affect sleep quality, but even endanger physical health.

What's more, snoring is not only a problem of personal sleep disorders, but also an obstacle to social and family life. Especially in the nights of quiet nights, any small sounds may affect the sleeping state of the people around them, let alone the continuous snoring thunder? Even let the pillow people can't stand it, so sleep in the room and affect the couple's feelings.

To this end, there are people who are troubled by snoring, not only personal problems, but also the whole family, even the problems of the neighbors and the work team, which should be paid attention to and treated.

However, there are many reasons for snoring. The diagnosis and medical behavior are mostly long processes and cannot produce immediate effects. Moreover, some people may only be fatigued for a while, and occasionally they may not be able to predict effectively.

Therefore, the troubles caused by the snoring of others are still happening every day. In addition to patience, we can only choose to stay away.

To this end, the inventor of the case felt that although the war was small, it had to be taken seriously, so it was actively studied and the law could be resolved.

In the past, in order to alleviate the phenomenon of snoring, squatters must be consciously seeking solutions before going to bed to reduce the impact on others. However, if the snorer does not know it or the solution is invalid, then the snoring person has no effective solution, and can only let the snoring continue.

Therefore, the inventor's main idea is to be passive and active, so that the process of easing the snoring is carried out automatically, without being subject to the personal restrictions of the snorers.

Since the hum is also a kind of noise, it can naturally be solved by noise elimination. Common noise cancellation technologies include Passive Noise Control (PNC) and Active Noise Control (ANC). The passive method is to use the isolation method or the material that absorbs the sound to block the external influence of noise. This method needs to install the blocking material at the noise source, which is obviously not applicable to the human body; the active principle is to detect and analyze the noise. The component then drives the speaker to generate sound waves with the opposite phase but the same amplitude, so that the sum of the sound waves in the sound field is zero, and the effect of canceling the noise is achieved. This method has little change to the noise source and the surrounding environment, so the method used in this case is adopted. Feasible technology.

Then, in order to instantly eliminate the hum, we need a device that can receive sound, analyze, and generate inverted sound waves at any time. The noise-eliminating devices that are currently seen are mostly large-scale, professional machines for unspecified sources of noise, and use a large amount of computing power for noise analysis to eliminate noise. Fortunately, the buzz is a specific noise. The source of sound, its acquisition and analysis methods are relatively easy, coupled with the rapid development of technology, the current popular mobile phone devices, have the relevant capabilities, as long as they are properly used, can play the functions required by the present invention.

Through the long-term research and development and implementation of the inventor, the method and device for detecting and eliminating hum noise by using the mobile phone can be finally completed.

With the foregoing device, the present invention utilizes a mobile phone to detect and eliminate click noise, and the steps are as follows: a. placing the mobile phone in a range that can detect the snoring sound of the snoring person, and making the microphone of the mobile phone face the snorer ; b. turning on the noise canceling software in the mobile phone, the noise canceling software obtains the signal of the click sound from the microphone, and then analyzes to generate an acoustic wave signal having the same amplitude and opposite phase as the click sound; c. passing the sound wave signal through the The speaker output of the mobile phone is to eliminate the sound wave, so that the sum of the amplitude of the canceled sound wave and the click sound is zero in the range affected by the click sound, and the elimination of the click sound is completed: and d. Repeat steps a~c to continuously eliminate The action of the buzz.

In actual operation, the snorer's surroundings should be kept quiet to reduce the external noise to interfere with the judgment function of the noise cancellation software.

Further, the noise canceling software is provided with a noise comparison database which is preloaded with a plurality of click data or a personal sound data exclusive to the snorer.

Therefore, by comparing the click signal with the noise and the noise data pre-loaded by the database, the speed and correctness of the sound signal generated by the noise canceling software can be increased.

Alternatively, the noise cancellation software is used to record the sound of the click sound, and the personal sound data of the snorer is created and stored in the noise comparison database to increase the speed and correctness of the sound wave signal when the snorer is used again. Sex.
