Equipment of the match, is a terrible thing, and you open audio magazine, just told you to figure out how many brands in the world, no one dare to give you the answers, plus every brand will produce different models, each brand of timbre orientation vary, even if you have the ability to bring equipment with this with that, you may experience (and sometimes intuition) put in hand the only equipment or wires for the match, the adequacy of the test results are very often argue, ladies only for reference.
Following on the other the fundamental factors affecting the sound, but also because of these factors, the only thing enthusiasts can play, and these factors can be understood that there must be at the school of sound. The first is the environmental factors, the second is the human factor. Let's talk about environmental factors, this factor is the most complex because it includes the following features: 1. to listen to a total shock characteristics of the environment; 2. external vibration; 3. sound vibration of transfusion; IV. listening room acoustics
Environment of total shock characteristics to use the Spectrum Analyzer to test, the room of the frequency response curve like the Dragon-like high and rugged, even if you used the equipment how advanced, will be subject to this room's acoustic properties, how to eliminate or mitigate the effects of this room, so that the innate response straight, combined with good performance, depends on your playing skills. Room to easier handling of rectangular, the cream of the square room, standing wave special and powerful, it is difficult to handle, slightly understand sound friends all know this is almost the death disease is difficult to have a pretty sound.
External vibration: some listening room near the roadside or close to the factory, or the next door is the lift room or pump room and the like, are often subject to car passes and machine caused by noise or low frequency effects, hi-fi sound affected by vibration and blurred, this situation appears to be only moved house or imitate the Design Studio, in the House to do a cut with the outside and float in the room, doing full soundproofing measures before they can be avoided.
Sound transfusion shock: when reproducing the work, sound combo will shake the walls, ceilings and floors, and some directly or indirectly impact audio equipment, these vibrations through different media, for instance Hi-Fi rack and air with different speed and strength has been to give back to the equipment, caused by equipment vibration and resonance produced its own, causing the work equipment lines produce delicate electronic flow changes the sound changes, with the result that sound blurred, it can be said is a distortion. Available on most of the commitments on audio equipment accessories, such as nail foot, what sort of wood, steel products, are designed to deal with this kind of resonance and production.
Listening room acoustics: in addition to above mentioned listening room congenital due to scale and shape of the impact of frequency characteristics of each hearing room construction, materials, and the future in the interior decoration made of materials, furnishing, furniture, curtains, etc. everything will put the original natural sound characteristics change, these changes can predict or calculate, but a lot of unknown factors, such as construction, decoration of brought in with the future of furniture materials, carpet thickness, location, and display is difficult to estimate, and no data available, even sound engineers also took it. That is why smart enthusiasts take it for granted to casually design, they only look in the future to analyse the room acoustic properties, and then use currently available can be used as a tuning of the material, or for example RGP plate, RoomTure, Sonex, diffusion plates such as professional materials to good room characteristics, often better than blindly self-righteous to mess up a pass, but difficult to reassemble.
