Folk guitar, when I just bought it, I thought the sound was ok. A few days later, I found that the guitar was very noisy, with six strings, five strings and four strings. What happened?

The reasons why guitar strings make noise are as follows:

First, the string is too loose, and the amplitude of the loose string is too large, and there will be slapping and hissing. In this case, it may be just one string, or it may be that several strings have been hit.

Second, there are sundries on the strings, such as magnetic iron filings and small metal wires.

Third, there is a kind of noise that is not noise. As we know, except for the first string and the second string, all metal strings are wound with coils of thin metal wires, so the new string will have sounds other than string vibration. Some people think this is noise, but it is not. There is no such sound in the old string, because the gaps between the metal rings are filled with impurities such as dirt, dust and rust, so there will be no such "redundant" sound.

What is the reason? Careful examination from the above aspects will reveal the problems.
