Does a cracked soundboard of an upright digital piano affect the sound quality?

The sound quality of an upright digital piano depends on the resonance soundboard of the strings, so the production of the soundboard is a trade secret of the piano manufacturer. In the four seasons of continuous changes in temperature and humidity, a traditional soundboard covering an area of 1.5 square meters and only about 8mm thick causes cracking, especially in the dry winter in northern China, which is very extensive. This type of cracked soundboard is not difficult to recover and can be sure that no traces are left. So do you know if a cracked soundboard of an upright digital piano will affect the sound quality?
Because the average customer even has a grasp of the upright gangpiano, it will feel that the soundboard is cracked, which is a great problem. In fact, it was unexpectedly found that some upright pianos originally had a thick sound quality, and once the piano plate was cracked, the sound quality not only did not suffer, but was brighter and more penetrating. Many long-standing upright digital pianos have been used for decades, and although the soundboard is cracked, the sound quality is still clear and simple. When the maintenance personnel seriously recover, the glue will be cracked and repaired, and the sound quality is not as good as before, which increases regret. In fact, the soundboard cracks, as long as there is no noise, there is no harm to the sound quality, or even better.
