Is a solid wood soundboard the same as a solid wood composite soundboard?

Solid wood soundboard and composite soundboard The selection of materials for the soundboard is very important, and a good piano such as Steinway & Sons uses spruce, because of its sound transmission and good resonance. The length of the tree itself also has a direct impact on its quality. At present, there are basically the following types of soundboards---1, natural drying [solid wood], the longer the drying time, the more stable.

2. Mechanical drying [solid wood], can't wait for the product of natural drying. 3. Composite, to avoid the cracking of the solid wood soundboard caused by incomplete drying. Soundboards are very sensitive to changes in temperature and humidity.

Only natural air-drying of soundboard wood for a considerable period of time can keep the wood stable and not be affected by too much temperature and humidity. But that doesn't mean it's unaffected, and nature's heat and contraction can be applied to any soundboard. When the temperature and humidity of a piano like Steinway & Sons fluctuates greatly, the sound is also affected, and the response of the mechanism is also slow.

Therefore, the general foreign ** hall is constant temperature and humidity, or at least basically stable. However, even if the soundboard with a long natural drying period encounters large changes in temperature and humidity, it will generally not crack [piano aging is of course another matter]. If the natural drying period of solid wood soundboard is not long enough, or the mechanical drying is not complete, once the temperature and humidity change greatly, it may crack.

In the early days of Chinese piano exports to the United States, this situation occurred due to the unadaptability to the American climate. Solid wood soundboards are mechanically dried, but they have to be done to increase production. At present, the vast majority of the world's solid wood soundboards use this method.

Even some high-end grand pianos are naturally air-dried in combination with mechanical drying. Due to the popularity of pianos and the need to increase production, composite soundboards have become an alternative to solid wood soundboards, especially in popular pianos. To a certain extent, the composite soundboard basically avoids the cracking caused by the instability of the wood when the temperature and humidity changes without the need for a long time to dry naturally, but at the same time, it also sacrifices the natural sound transmission and resonance of the solid wood soundboard.

It can be said that the composite soundboard is the method that the assembly line has to use for high-volume rapid production, and it is not the best choice for the piano soundboard. However, for the average piano learner who is not very picky about the sound, choosing a compound soundboard does not affect learning and practicing. All in all, the quality of the wood used on the piano [including the soundboard] depends on a series of factors such as the selection of materials, the method of manufacture, the time and method of drying, and the workmanship.

The ** of the piano also directly reflects the above factors. For the average piano learner, solid wood or composite does not have much impact on learning; Users who have higher sound requirements or more economy can choose solid wood pianos as much as possible. Whether it is solid wood or composite, trying to keep the piano in a relatively stable temperature and humidity environment is the foundation to keep the piano in the best condition.

The best soundboard is a solid soundboard soundboard with unequal thickness veneer, followed by a soundboard with unequal thickness plus solid wood soundboard.

The soundboard is the vocal part of the piano, which is equivalent to the soul of the piano. The quality of the soundboard directly affects the sound quality, timbre, and service life of the piano.

All soundboards are solid wood soundboards, so the feature of solid wood is basically negligible.

First of all, the soundboard is made of wood, if someone tells you that the whole soundboard is a piece of wood, it must be fooling you, because there is no such big tree at all, there are insect eyes in the book, and the nodules cannot be used to make the soundboard, the soundboard is made of the most essential part of the trunk, and the texture is consistent to be spliced well.

It is also a solid wood soundboard, and a veneer soundboard is a soundboard made of large pieces of wood, and on the basis of consistent wood texture, the large pieces of solid wood planks are spliced together, which has extremely high requirements for technology and manufacturing technology. The reinforced solid wood soundboard or ordinary solid wood soundboard is wrapped with wood veneer on both sides of the soundboard, and the middle is filled with finely broken small wooden blocks, which is a whole wooden board from the surface, and there are no obvious splicing traces. The resulting soundboard is made of glue that binds and presses wooden blocks together and then wraps them in veneer.

However, if the glue cracks in the later stage, it will be prone to noise. The general public has very limited ability to distinguish whether it is a veneer or not. It is difficult to identify the greasy, and coupled with the salesperson's open-mindedness, it is easy to be deceived.

The easiest and most effective way to identify whether it is a veneer soundboard is to look at the introduction of the product on the official **, if it is a veneer, it will definitely be written on the official **. All the solid wood soundboards that are not said to be veneer soundboards are not veneer soundboards. So don't listen to others, you have to screen on the official **, the official ** will not deceive people.

First, the advantages of sound-absorbing panels.

1. Excellent sound absorption performance.

2. The real environmentally friendly acoustic material, the process of wood sound-absorbing board is the molding process of traditional MDF, and this adhesive material is an inorganic adhesive material, so it completely eliminates formaldehyde that is harmful to the human body.

3. High fire performance and good heat insulation, the fire rating has reached B1 level, and the flame retardant performance is excellent.

4. It can be cut and installed freely, and the construction is simple.

5. The quality is light and safe, and the wooden sound-absorbing board minimizes the load of the decorative ceiling and wall, making it safer and more labor-saving.

6. The decorative effect is also very good, catering to the design trend of returning to nature in Europe and the United States, and does not need surface decoration. It can also be applied in any color, and it has a rich beauty.

Second, the shortcomings of the sound-absorbing panel.

The advantages of strong environmental protection and light weight of sound-absorbing panels also determine that they are slightly expensive.

If my help to you, I hope to give you a five likes, thanks

Hello, I am happy to serve you and give you the following answers: solid wood soundboards are mainly used to make musical instruments, and the timbre of wood is warmer and has a deep thickness, which is easier to form a warm sound. Unequal width and thickness soundboards are used to make wind instruments, they can better control the tone of the tone, can be more easily adjusted timbre, easier to control the timbre variation, and give the instrument more ahallusable energy.

As a result, soundboards of unequal width and thickness are more suitable for wind instruments, while solid wood soundboards are more suitable for stringed instruments. The reason for the problem can be due to factors such as the manufacturing process, the quality of the materials, the temperature and humidity of the production environment, etc. Workaround:

1.Ensure the correctness of the production process: When making the soundboard, you should ensure that the process is correct, such as splicing, sharpening, baking, polishing, etc.

2.Choose high-quality materials: When making soundboards, you should try to choose high-quality materials, such as wood, fiberglass, etc.

3.Control the production environment: The temperature and humidity of the production environment should be controlled when making the soundboard, so as to ensure the quality of the soundboard.

The above is the relevant knowledge and solutions about solid wood soundboards and unequal width and thickness, I hope it will be helpful to you.

Both solid wood soundboards and unequal widths and thicknesses have their own advantages and disadvantages, so when choosing, you should choose according to your actual needs. The advantage of the solid wood soundboard is that its texture is soft, the sound is crisp, and the sound emitted has a good sense of rhythm in the congratulatory draft, which can better express the emotions of the first place. In addition, it also has good durability and can be used for a long time, so as to save costs by Zen Mo Xiao.

The advantage of unequal width and unequal thickness is that it has more variations, which can better represent the changes of the **, thus making the ** more vivid and interesting. In addition, the soundboard of unequal width and thickness can be adjusted to better express the emotion of **. In general, both solid wood soundboards and unequal widths and thicknesses have their own advantages, and depending on your needs, you can choose different soundboards to meet your needs.

Solid wood soundboard – usually made of radially cut spruce or fish scale pine, requiring a board width of 100mm and a billet thickness of 11-12mm. After drying, the moisture content reaches less than 8%, spliced between the boards, according to the angle of the soundboard designed by various pianos, the thickness of the sanding is 7-8mm, the edge is trimmed, and the soundboard is made of ribs (the role of the ribs is to support the soundboard to form a unique arc).

Solid wood soundboards have extremely high requirements for materials: the grain of growth rings is between 2mm-3mm, the diameter cut board, the board, no knots, no early eyes, no oil lines, and no decay marks. In this way, the yield of wood is low, the production process is complex, and the moisture content should be controlled between 6-8% by hand-splicing with environmentally friendly bone glue, which leads to a long production cycle and high cost.

However, the sound transmission speed of the solid wood soundboard is fast and penetrating, and a beautiful sound can be obtained. Internationally famous piano productions, such as the Steinway piano from Germany, the Besendorf piano from Austria, and the Pétrof piano from the Czech Republic, all use solid wood soundboards.

Composite soundboard (including solid wood veneer soundboard) - the role of composite soundboard is not very particular about the materials, and the internal wood is not very demanding, as for the board with insect eyes, knots, oil lines, decay marks and other phenomena and medium-density fiberboard can be used for processing, as long as the appearance is clear. Therefore, the production cost of this kind of soundboard is low, the production speed is fast, the production cycle is short, the sound conduction rate is slow, and most of the pianos with poor timbre are composite soundboards, which are suitable for large-scale mechanical industrial production of piano production enterprises (such as domestic low-end piano Pearl River, Xinghai, etc.). Generally speaking, popular and practice pianos use a composite soundboard, and mid-to-high-end pianos use a solid wood soundboard. ”

Each has its own advantages, but the cost of solid wood veneer is higher, for example, Yingchang is basically a soundboard of solid wood veneer, and Yamaha's YA series has just been replaced with solid wood veneer.

The soundboard, if it is composite, it is more stable, but it has no penetration, and it will not work if it is played for a few years, and if it is solid wood, there are Europe, North America, and Northeast China, which are more famous, and the timbre is penetrating, more natural, and the more you play, the better. At present, Yingchang is the most solid wood used in the domestic market.

It is not recommended to have a composite board, of course, it is better to choose a solid wood soundboard, and it is recommended that the landlord go to see Yingchang's piano to understand, and the reputation is very good.

Solid wood soundboard The timbre is purer and more sound-sounding, you can take a look at Yingchang's piano.

At present, only Yingchang in the domestic market is solid wood veneer, no veneer.

Yes, the piano soundboard is mainly composed of a resonance board (also known as a soundboard board), a rib wood (also known as a stall), a soundboard frame and strings. The piano soundboard determines the resonance effect (called resonant frequency in audio), the level and richness of overtones (called multiple harmonic components in audio) and the speed of sound propagation, which constitute the key indicators of piano quality, which are all grouped into one word, which is the "timbre" of the piano.

Solid wood soundboards are mostly used for high-end pianos, and composite soundboards are mostly used for low-to-mid pianos. The selection, processing and bonding of the piano solid wood soundboard is a very great work, these processes will play a role in controlling the resonance frequency of the piano, the speed of sound propagation and other factors, it is installed into a piano, but also through continuous adjustment, to achieve the ideal state. A good solid wood soundboard piano has extremely rich overtones and distinctive personality characteristics, is a work of art, art is to pay attention to personality, excellent solid wood soundboard piano each finished timbre will be different, really smart children have different cuteness, if this is a high-level performance piano, it must be a solid wood soundboard, and the use of different solid wood raw materials and processing technology will form different timbre genres, such as suitable for the performance of Chopin, Liszt, Tchaikovsky works of different performance pianos.

The piano solid wood soundboard must be processed by hand, and the maker must be an artist, and the nuances in this are very large, so it cannot be made in batches, so it is **high. This is the disadvantage. In addition, the solid wood soundboard is bonded together with glue, the life of the piano is relatively short, the soundboard is easy to crack, and the piano is basically warped when the soundboard is cracked, and it is not good to repair.

Therefore, the solid wood soundboard piano must be placed in a very dry place, and if it is not maintained well, it will die quickly. In 1979, Isaac Stern went to Shanghai for the first time to play the violin, his son piano accompaniment, the Shanghai ** hall that has only been in use for 5 years of high-level performance piano (of course, it is a solid wood soundboard) has been damp soundboard cracking, Stern proposed to transfer a military aircraft from Beijing, whimsical, the result is from the Shanghai People's Radio called a 50-year-old piano, because the radio building is better, and is perennial air conditioning (for broadcasting equipment), the soundboard of this old piano is still tight. That's where the trouble with a solid wood soundboard piano comes in.

I saw this from the Oscar-winning documentary "From *** to Mozart").

The piano composite soundboard is made of multi-layer composite panels, which can be mass-produced after determining the process, so the timbre is easier to control, the consistency is good, the first is low, strong and durable, and the life is long. Generally, the collection conditions are not good, or the piano is mainly practiced, and it is more economical to use a composite soundboard.

But the problem is not absolute, under the banner of solid wood soundboard piano, ordinary people can sell ** solid wood soundboard piano casually, maybe not as good as the general composite soundboard piano. In composite soundboard pianos, brands like kawai and Yamaha are also very good if they are not too high.
