What should I do if my voice is noisy? How to deal with noise in sound?

In daily life, after the audio is used for a long time, it is easy to have various problems, and the noise in the audio is one of the most common problems. What if there is noise in the stereo? Let's take a closer look!

What if there is noise in the stereo? 1. Check whether the microphone mix is at its maximum, preferably 80% to 90%.

2. Check whether the microphone is in a reinforced state, and remove the microphone reinforcement, which may not be supported by the sound card.

3. See if there is any connection problem, and see if the connection between the microphone and the computer host is broken.

4. Play in a good indoor environment to see if it is normal.

The problem of the computer motherboard is to connect one end of the metal wire directly to the ground and the other end to the outside of the computer host.

The common cause of noise in audio is 1. Noise in audio is mainly interference-free sampling ability, which is embodied in the choice of microphone and sound card.

2. Power supply problems may lead to current noise.

3. The problem of earplug itself

4. Sound card problem

5. The problem of software settings

6. Network problems

Solutions for different reasons satellite speakers are damaged, which will cause noise. A large part of the problems are caused by satellite speakers or sub-boxes. This failure may be caused by the amplifier circuit of the speaker or the speaker itself. For example, when listening to a song, the volume is adjusted too much, which leads to the cracking and damage of the high-pitched or low-pitched part of the speaker unit, so there will be noise if you continue to use it.

Solution: If this is really the reason, it's a pity that we can't solve the problem fundamentally, so we have to repair your speaker.

The problem of file quality is that online music is popular now, and many songs are downloaded from the internet, which is very convenient to use. But it is precisely because of this open platform that the quality of documents is mixed. For example, some music files are not small when they are downloaded, but the quality is not very high, and noise will be generated when they are played. This is a problem in the process of document suppression, which is almost impossible to solve.

Solution: We can only improve the quality of music files, and there is no other way.

Incorrect line input Whether it is 2. 1 speaker or 2.0 speaker, there is a connecting line from the sound source to the speaker, that is, the signal line for line input. If this signal line is not connected properly, it is likely to produce noise. For example, the general 3.5mm signal line is a two-stage plug. If you don't plug it in, there will definitely be noise, even a silent channel. Of course, if the line input is not true, it will also cause the chassis itself to leak into the audio line, and the noise will be more serious.

Solution: Plug in the signal wire and ground the chassis.

The reason of mobile phone interference If there is noise in your speaker only under special circumstances, it can almost be judged that it is a problem of mobile phone interference: the speaker works normally most of the time, and when a phone call or text message comes in, the speaker will have regular noise, resulting in abnormal use. In fact, this has something to do with the amplifier of the speaker. With the large-scale popularization of class D digital power amplifier, this phenomenon is expected to disappear.

Solution: Take away your mobile phone and put on a set of digital amplifier speakers.

The problem of sound card driver is very common and atypical, and it will only appear in special times. I met it once anyway. There is a new noise in the speaker, and all the troubleshooting methods have not been improved. After reinstalling the sound card driver, the fault disappeared. Don't throw away your speaker in the most desperate time, try changing the sound card driver. Solution: Reinstall the sound card driver or replace it.

The causes of electromagnetic interference can be mainly divided into power transformer interference and stray electromagnetic wave interference. Generally speaking, the interference of power transformer is caused by the leakage of multimedia speakers. If there are conditions, the effect of installing a shielding cover on the transformer is very obvious, which can block the magnetic leakage to the greatest extent. The shield can only be made of iron-based materials. Try to choose products with big brands and solid materials. In addition, using an external transformer is also a good solution. Stray electromagnetic interference is very common, and speaker cables, frequency dividers, wireless devices or computer hosts will all become interference sources. The main speaker should be as far away from the computer host as possible to reduce the surrounding wireless devices. Mechanical noise is unique to active speakers. In the working process of power transformer, the vibration of iron core caused by alternating magnetic field will produce mechanical noise, which is very similar to the hum of fluorescent lamp ballast. Choosing good quality products is still the best way to prevent this noise. In addition, we can install a rubber damping layer between the transformer and the fixed plate.

It should also be noted that if the potentiometer is used for a long time, the metal brush will have poor contact with the diaphragm due to dust accumulation and wear, and noise will be generated when it rotates. If the screws of the speaker are not tightened, the inverter tube is not handled properly, and mechanical noise will also be generated when playing large dynamic music. This thermal noise can be dealt with by replacing low-noise components or reducing the workload of components. In addition, lowering the working temperature is also one of the effective methods.

In addition, when the volume is turned too high, some computer speakers will make noise. The reason for this situation may be that the output power of the power amplifier is small, which can not avoid the large dynamic peak signal at the moment of music, or the loudspeaker is overloaded and distorted.
