Great Audio Systems are made up of a variety of components. Each of the components has an impact on the final sound quality. Amplifiers and speakers are some of the more commonly known components, but there are many items that should be considered as important components. 1) Power: Audio adheres to the old adage of garbage in garbage out. With that in mind it all starts at the wall receptacle. Audio and Video equipment works better, if it is fed a clean power source. Radio frequency interference and electromechanical interference, are two common problems that degrade power line performance. In order to allow equipment to work at its potential it is best to try and eliminate or minimize these negative effects. Independent audio and video circuits isolated from all other internal house wiring with a separate ground and connected to hospital grade receptacles, will provide an excellent power source. Power line conditioners and surge protectors are recomended additions to any audio or video system. 2) Room Acoustics: Room acoustics can have a huge impact on sound quality. You can go out and buy the best audio equipment in the world, but if you set it up in a room with poor acoustical properties, you will never hear what the system may be capable of. Small audio and home theater rooms suffer from different types of sound distortion which can seriously degrade audio quality. In theory a flat frequency response which is balanced across the frequency spectrum, is to be strived for. In reality a perfectly flat frequency response is almost impossible to obtain. What is possible in most small listening rooms is to even out some of the major dips and peaks in frequency response and at the same time dampen major resonance's and room modes , which are created by standing waves. Room control is achieved through two main forms . Absorption and diffusion. Absorption is simply the soaking up of sound waves, and is achieved when air particles come in contact with materials and lose some of their energy in the form of heat. Diffusion is a process whereby sound waves, particularly high frequency ones, which tend to travel like beams , are scattered and broken into diffuse fields. |
