Chào các bác ! Có nhà sản xuất ở Nhựt Bổn sản xuất bông tơ thiên nhiên dùng cho hệ thống audio. Bác nào rành xin dịch dùm em ạ ! Data demonstrates No.1 characteristic as speaker sound absorption material!Glass wool,wool,cotton,urethane foam and carbon paper wool is used as conventional sound absorption material.These materials did not have flat sound absorption characteristic.This is because,fibrous cell of each material was uniform.This made the particular peak and dip. We adopted natural silk for PSA-100.The reason is,natural silk material alone has a random fibrous cell.Natural silk has a flat sound absorption without having particular peak and dip. Cancellation effect on stationary wave around CD player & amplifier Harmful stationary wave occurs around CD player,amplifier and power supply tap.By placing small quantity of PSA-100 around equipment cancels harmful stationary wave by a distinguished diffusion effect. In addition,harmful static electricity occurs around power supply cable and various cable input and output terminal.With the help of natural silk of PSA-100, it removes effect of static electricity.The result is dynamic sound and improved transparency and remarkable S/N ratio.
Và tài liệu của tấm tán âm đây ạ : Theory and structure Diffuses reflection and sounds from speaker ideally by its special material ditch which has different depth. RWL-3`s ditch has been designed by computer analysis and listening test. Also carefully calculated curve will diffuse sound in wide space compared from other diffusing type room tuning panels. The high-tech natural silk material and special foam material which contains Tourmaline releases negative ion which will make the sound very smooth and materializes excellent sound quality. Effects Sound absorbing type room tuning only kills sound RWL-3 only tune and diffuses sound ideally so it does not kill sound like sound absorbing type room tuning such as glass wool, thick chemical fiber and room tuning using the Helmholtz principal. You have to remember that any sound which has been absorbed will never come back again. Sound absorbing type room tuning takes away musically necessary elements such as feeling of energy a feeling of throbbing pulse. RWL-3 only eliminates unwanted elements like reflection, flatter echo and standing wave so the sound released by the speaker becomes very clear and at the same time, feeling of sound volume and energy will increase Conventional diffusing type room tuning panels problems solved I`m sure that many people have listened to audio in a room which has expensive diffusing type room tuning which said to be analyzed by computer. People which who have listened to these room tuning must have experience sound such as pore sound position, corrupted sound stage and in a worst case, pore phase characteristics. This is because, unnecessary reflection occurs inside the room tuning random ditch and an outbreak of huge cross-modulation distortion stays inside the ditch. Diffusion type room tuning materials which said to have each frequency band analyzed by computer has not put elements in account such as room size, shape and a type of speaker and size. This is a reason why cross-modulation distortion happens inside the ditch which destroys sound quality. RWL-3 not only depended on computer analysis, few hundred of trial products were made and few hundred of listening test was taken place. These test and trial products created an ideal curved diffusion structure which leads to superb phase characteristics, solid sound position, wide and deep sound stage. We are confident of people who have doubts with conventional room tuning will feel and listen to the excellent room tuning characteristics of RWL-3. Even just placing only one RWL-3 at the center between the two speakers. Tourmaline contained natural silk & foam material which creates an overwhelming smooth and natural feel and sound toneWhen you use a conventional room tuning material, sounds tend to loose a gloss and moisture feel and becomes dry and rattled sound. This is because most of room tuning materials surface including diffusion type room tuning uses chemical fiber. The room tuning materials surface creates reflection even if its absorbing type room tuning materials surface. This reflected sound joins the sound from the speaker. A chemical fiber carries a uniform fiber which has an outbreak of a peak (resonance) and this peak become an unpleasant and irritating reflection which destroys the played backed sound from the speaker. We adopted a natural top quality silk as an RWL-3`s surface material. Silk is the only fiber which carries a random tissue and does not have an outbreak of peak (resonance). So it is possible to get a very smooth and excellent quality tone. Further more, RWL-3`s silk material contains Tourmaline which releases negative ion. As you know, silk is produced from a silk thread which released from silkworms mouth. The leaf which the silkworm eats is added with Tourmaline powder. So Tourmaline is naturally contained in the silk. Also the curved ditch which has a random depth is made from special foam aterial which also contains Tourmaline. So together with the silk surface material, RWL-3 releases a strong negative ion effect. Negative ion improves the sound viscosity and makes the sound wave transmission smooth which leads to clear, excellent resolution, smooth and high quality tone. RWL-3 will exceed conventional room tuning materials concept and sound quality which will give you very smooth and natural tone. This is because, RWL-3`s design and material is carefully chosen to perform high quality room tuning in any kind of room. RWL-3 will change your room acoustic and give you superb phase characteristic, sound position, wide sound stage, detailed information and realistic tone which you have never heard before, and we are confident that your room acoustic will exceed studios which is said to be acoustically carefully thought
