Acoustics is an almost elusive, unpredictable science. Over the years, Acoustics experts have tried their best to find the ideal ratio, which is the "golden ratio" in the mouth of enthusiasts. There are different opinions about the "golden ratio" experts, one of which is more inclined to me, that is 0.618:1:1:10618, which is 8 feet high, 13 feet wide, 21 feet long, and a space volume of 2,184 square meters. ruler.
The ratio of 0.618:1:1.618 is the oldest legend, from Leonardo Fibonacci. He took the secret of pyramid construction in Egypt in the twelfth century. He got a numerical ratio of 1:0.618. Three hundred years later, mathematician LUCAS PACIOL conducted in-depth research. Finally became one of the many ACOUSTICS doctrines, namely 0.618:1:1.618.
It has been used in this proportion to make pyramid-shaped objects with thick iron wires, which are said to be used to hide things that are prone to deterioration and have more lasting effects, such as food, blades and so on. Someone has done such an experiment, placing two wet water blades inside the tower and outside the tower. The outer one began to rust after five days. One of the towers turned out to be as sharp as it was, until it was more than a month before the rust was seen!
In the proportion of the same room height, the larger the space, the greater the spatial sense of replay, the more ideal the replay of the low frequency, and the lower the weekly frequency. The high frequency cycle is very short, so a room of average size has no effect on high frequency replay. But the low frequency is another matter, the positive and negative wavelengths of 20HZ (week) have reached a total of 56 feet! Of course, the length is enough for a single positive wave to receive 20 weeks. This also requires a length of 28 feet. But this length is not a straight line measurement, and the sound wave is not a planar waveform that we can use from the gauge display. Moreover, the hemispherical object (unit) is diffused in a hemispherical shape in all directions at a maximum angle. In the book theory, a 10 foot high, 16 foot wide, 26 foot long room can have a diagonal length of 27.7 feet, and can also hear ultra low frequency of 21 to 22 weeks.
From this point of view, the room is very important to the sound. Whether the combination can be fully played is mainly the "house". Although the bigger the room, the better, but the final output power obtained from the market is subject to. The "space volume" should not exceed 20,000 cubic feet. The high, deep and wide volume of this kind of volume is enough to reproduce a few real senses of the scene with the equipment. No matter the depth and space of the sound field, there is a magical feeling. The quieter the room, the easier it is to respond to the output power of the rear stage. Therefore, the better the sound insulation design, the better. ACOUSTICS can further improve the effect of “roomâ€, not only improve common problems such as standing wave and sonic interference, but also create an illusion space larger than the actual volume, thus obtaining a more excellent on-site experience.
