The service life of the dulcimer is closely related to the conditions of use. Affected by factors such as the external environment of the dulcimer, temperature changes, the force value of the violin body or the change of humidity, the service life of the dulcimer will be different.

Generally speaking, according to the technical level and craftsmanship of domestic dulcimer manufacturers in making dulcimer, under the condition that there is no external force damage, the relatively stable use conditions will make the dulcimer used for a long time. In the case where stable conditions of use cannot be guaranteed, the average lifespan of dulcimer made of ordinary materials should be more than ten years. Dulcimers made of high-quality materials are not affected by this time limit and will be used for a long time.

The primary condition for determining the sound quality of an instrument is the level of production materials and production processes. Under normal circumstances, standard dulcimer manufacturers first consider the overall design from the procurement of log materials, wood processing, selection of production materials, refinement of production processes, optimization of dulcimer structure, manual improvement and adjustment, etc., from the source materials. , until the production process, before the tuning process is completed, there is a special sound quality testing department responsible for sound quality debugging and optimization. The basic sound quality standard of dulcimer can reach the national standard.

Production practice shows that the conditions that determine the sound quality of dulcimer cover all aspects of dulcimer production, and which link will have an impact on the sound quality of dulcimer. Therefore, the details of each link in the production of dulcimer should meet the production standards of the production process. Produces the dulcimer of the best sound quality.
