Help: Why does my erhu always have noises

There may be several reasons for the murmur of the erhu:

1.Factors in terms of design layout. For example, if the resonant resonance focus area is not formed in the barrel, or if the focus area is backward, it may cause a false treble and noise.

2.Factors in the manufacturing process. If the production structure is not tight, the wood is defective, the skin is too tight, and the thickness of the skin is uneven, etc., it may lead to the noise of the "Penny Breaking" effect.

3.Playing technique and environmental factors. For example, when a player plays with a bow hair touching the barrel, or when the bow collides between two strings, it can cause noise. In addition, in cold weather or humid environments, the leather is prone to moisture, which will also affect the sound quality.

In order to solve these problems, you can try the following:

1.Adjust the layout inside the barrel so that the focus area is correct.

2.Improve the production process and improve the quality of the instrument.

3.Improve your playing skills and avoid unnecessary collisions.

4.Pay attention to changes in the environment when playing and avoid playing in bad environments.

Hopefully, this information will help you solve your problem. If the problem persists, it is advisable to seek help from a professional.

It is normal for the newly bought erhu to have a wolf sound, which can be eliminated by using a flannel cloth or sponge pad under the piano horse. After being used for a long time, the erhu mangpi is often vibrated and the force in all directions is even, and the wolf sound will disappear. Generally, the erhu is often played, and the resonance effect of the barrel will come out after about half a year, and the sound will become mellow, of course, the longer it is played, the better the effect will be.

Therefore, the newly bought erhu should be pulled every day.

Erhu can not be exposed to the sun, if it is too humid, not noise, but no sound, you can put a little desiccant, the front brother must be joking, there is a noise to see that the position of the strings is not good, the saddle is not suitable, or the strings themselves have a problem, try to change the strings.

I also learned erhu Possible reasons: When pulling the bow, the bow hair is too close to the stem, or too hard Wipe the strings with a cloth to make sure there is no debris There are broken parts on the strings The strings are too weak or too heavy There is also a sponge stuffed on the erhu barrel is not suitable If you look at it again, it is not at all. Then find a piano repair shop.

Ask an expert, my erhu is a two-and-a-half-year-old qin, and the sound is tight and noisy, what is the reason? What's the solution.

The reason for the physical structure of the erhu itself: the type collapses Zen 1There is no way to get rid of the noise on a phoneme in the second position, but there is no way to eliminate it at the time of manufacture, except to add a piece of something called a "filter pad" between the strings and the python skin under the saddle.

It is usually made of sponge or felt, thick wool fabric. The size of the sponge is one inch square, one centimeter thick, and the felt piece is 3x6 centimeters. The noise is loud, the shirt is thickened, and the clip is loosened.

Try a few more times until there is no wolf sound and the sound is not muffled. If it doesn't work, try moving it down one to two centimeters to reduce the tension on the strings and the pressure on the snakeskin.
