(8)Summary

It really studied through this experiment. It is thought that you may do really though it was serious. When easily bringing it together

As for the [finrandoba-chi] material, a rich very beautiful sound is put out to the MDF material in an inside bass, and excellent in the vibration control [suru] ability has understood the box for a super-low region. Either [zai] doesn't have the influence in the high region part too much too much either. It was more changeless on f of the [ba-chi] material special though the high region level on the audibility was felt high.
Height in the effect of [ba-chi] was able to be actually felt by seeing according to musical instruments in musical instruments in the low region part such as the piano drums, stringed instruments in a low region, woodwinds in a low region, and order of the brass instrument and the voice.
You may raise the volume to the level by about ten o'clock and listen to know the sound of [zai] more clearly. There was in monaural listened in the state of the stereo by attention [suru] and was a source to understand the difference clearly, too.
A lot of advantages of MDF's were able to be found though this experiment was overwhelmingness of [finrandoba-chi] in most fields by the comparison between MDF and [finrandoba-chi]. As for the utility value, if this aims at the design that suppresses seasoning to the box as much as possible by "Few of seasoning" as for it, the reason why it is at 12 minutes and most of a present speaker on the market use the fiberboard such as MDF has been understood well.

Done what, and this experiment is things except f and [jimaidatta] to reliance it is not possible to show as for no scientific data. the subjectivity of my earHowever, the one that a mystery of [zai] of sounding world was made data has not seen me and it is not likely to be able to express it numerically through all eternity. (Of course, do not come to show the quality of the sound objectively in the place where the vibration of [zai] was displayed by a modal analysis by three dimensions. )In addition, it can be enough by yet another even resulting when the same experiment is done another times because it is a tree if MDF [finrandoba-chi] used this time also corrects the origin.

However, if such a trifling difference is put for the time being, the self-made sect sticks to [ba-chi] etc. even by here why, and thinks that a manufacturer on the market clings to MDF and [pa-chikurubo-do] and it was able to understand. It is after all architecture. The specific gravity of MDF�� [pa-chikurubo-do] �� hard board might come to control the sound still by using plywood that accumulates the soapberry such as [ba-chi] [supuru-su] and the pines used for the musical instrument material when it heavily faces, and the sound is valued if it aims at the one without the echo mechanically.

It might be for senior person that uses [ba-chi] plywood as self-made speaker materialThere is considerably a warp rage of [zai], and this is [poroporokakeruko] and ..tree.. [gaaru] from the chip side, etc. in case of [ba-chi] that stickiness is a little to be able to be likely to do the space if it doesn't harden it as the edge is strong in the bedroom clamping. cost three times or more MDF by the price to begin withIn addition, it might be a design of [enkuro] by which this sound is used what is the maximum difficult.

I never think MDF to be bad [zai] with considerably safe [zai]. I think that MDF is far more advantageous when thinking about poor and the difference of the quality of the lauan plywood (The China plywood also :) in recent years frankly speaking. (Wonderful and a good one for the lauan also : unusually though it is. )The reason why the Nagaoka teacher is specifying the lauan plywood for the book is that past lauans were far more high-quality and cheaper than the present one?(By the way, the lauan not only deteriorates in recent years but also the price has risen. How what is whether it is true or not in the woodwork industry though said well? pilfer this from a all over the world market China is the Olympics a large amount of wood)

This experiment was really probably studied and the problem etc. where it wanted to live came into view in the future. I want to tell the report that will understand the difference of the sound of [zai] a little more easily next time. It has abnormally taken time this time.
