Sound system in the fundamental factors affecting the sound – stereo, DVD player, amplifier – HC Network Appliance Industry
The combination of equipment is the pieces of deadly thing, you open the audio magazine, just told you find out the number of brands in the world, no one dare give you the answer, with each brand will produce different models, each brand sound approach is different, even if you have a skill, the equipment with this match that, you can only use their experience (and sometimes intuitive) to do only with the equipment or the wire to make it, if appropriate, test results often have The argument, so you only as a reference.
The following sound effects to talk about the other basic factors, but also because of these factors, the fans have things to play, but these factors can be understood that when the school certainly sound very helpful. First, environmental factors, and the second is the human factor. Here we only talk about environmental factors, this factor is the most complicated because it includes the following features: 1. Listen to the resonance characteristics of the environment; 2. External shock; three. Transfusion sound vibration; 4. Listening room acoustics characteristics.
Resonance characteristics of the environment if the test spectrum analyzer to test it, the room frequency response curve will be ups and downs as the dragon-like inequality, even if you use the equipment to advanced, also will be subject to the room audio features, how do you eliminate or reduce the impact of the room innate to respond to straight, make a good combination of performance, depends on your skill of play. The ratio of a rectangular room is easier to handle, very sensitive to the square of the room, standing waves in particular are many and formidable, difficult to handle, a little sound of friends know that this is almost incurable disease, it is difficult good time Jiang Sheng.
External shock: Some listening room or close to the factory near the roadside, or the room next door is a lift or pumping stations and the like, often passing by the car and when the machine running or ultra-low frequency noise caused by the impact of audio equipment so blurred by the vibration and sound, this seems to only move out or imitate the design studio, in the house cut off from the outside to do a float room, spare insulation measures in order to avoid.
Sound re-transfusion shock: When the sound combination of work, the sound will shake the walls, ceiling and floor, and some direct or indirect impact on audio equipment, these vibrations through various media, such as audio racks, and air at different speeds and intensity has feedback to the equipment, the vibration caused by equipment and produce their own resonance, resulting in the equipment lines on the work of the electronic flow of subtle changes to make the sound change, resulting in the phenomenon of sound vague, it can be said is a distortion. Most of the contractors put the market audio equipment accessories, such as nail foot, what wood, steel grit like products, are to deal with such resonance and production.
Listening room acoustic characteristics: In addition to listening room discussed above, the proportion and shape due to inherent characteristics of the impact on the frequency, each time listening room construction materials, and in the future when the indoors decoration materials, layout and furniture, curtains and all will feature the original audio congenital changes, some of these changes can be predicted or counted, but many unknown factors, such as decoration of construction, move into the future when the materials used in furniture, carpet thickness, decoration of the location It is difficult to estimate, there is no data available, even the sound engineer carries it no other way. Because of this, intelligent design enthusiasts take for granted to some random, they are more detailed views in later to analyze the acoustic characteristics of the room, then the current market can be used as material mixing, or with such RGP board, RoomTure , Sonex, diffuser like a good professional materials to adjust the room features, more often than blindly self-righteous way to chaotic mixing a pass in the end it difficult to get good.
