Acoustic requirements KTV stainless steel door Chongqing (Chongqing KTV acoustic requirements of a stainless steel door, background noise: KTV rooms not like the studio, background noise fills the room noise is too high, so listening to improve the signal range, undermining the sound signal. sound, resulting in clarity, intelligibility decrease external noise soundproofing treatment needs, the need to control the internal noise in the choice of Chongqing KTV 2 door equipment background noise as low as possible, the reverberation time:... KTV rooms mix length, the size of the reverberation time reverberation intensity sound of a great impact for a long time, the sound will be cloudy, affecting the clarity and intelligibility; reverberation time is too short when there will be singing voice is very dry very astringent, lack brightness and deep feeling for the KTV room to sing easy, no feedback (whistle) 3, diffusion: diffusion is an important indicator of today's KTV room acoustics uniform sound dispersion refers to various points in the sound pressure. level control within a certain range, which requires a certain gain sound, the sound in 4-room frequency response characteristics of the package uniformity: Different KTV package room decoration materials will have a different sound absorption characteristics. absorption and reflection is not the same problem arises frequency response of rational environment package room should sound field for each frequency reflection and absorption of otherwise relatively uniform distortion and distortion 5, the sound focus: When sound waves hit When concave interface stainless steel trash, the sound will generate acoustic focusing phenomenon caused by the sound at some point especially loud, indoor sound pressure uneven phenomenon, severe in this region can not sing, microphone to get here will produce whistle. (Chongqing steel door) laser cutting of stainless steel processing Chongqing Chongqing material analysis of copper and brass, stainless steel processing two materials have a high reflectivity and very good thermal conductivity. brass thickness of 1mm or less can be cut with nitrogen ; thickness of 2mm or less copper can be cut, processed with oxygen gas required parameters can refer to other nickel-chromium steel when oxygen cutting, cutting surface rough and hard on the system is installed only in the "reflection absorption" means when they could... Cutting copper and brass stainless steel stainless steel cutting needs: use of oxygen, it does not matter in the case of the oxidation of the edge; the use of nitrogen to obtain a non-oxidizing burr edge, there is no need for further processing of the plate thickness of 4mm, can be used. As a high-pressure nitrogen gas cutting machining titanium plate with argon and nitrogen as the process gas to cut. Because of its high purity aluminum is very difficult to cut stainless steel screens, only installed on a system of "reflection absorption" means the time to cut aluminum Aluminium Despite the high reflectivity and thermal conductivity of stainless steel, aluminum can be cut below 6mm thickness, depending on the alloy type and lasers ability at the plate surface coating film will get better results perforation, without reducing the processing quality. otherwise it will destroy the reflective optical components. thickness of 10mm or more of the plate, on the use of special plates and laser machining the workpiece surface is coated with oil to get better results. In this case stainless steel glass door, cutting edge is not oxidized . with nitrogen, the cutting surface smooth. Structural steel will get better results when cutting with oxygen. Otherwise it will destroy the reflective optical components. When using oxygen as the process gas, the cutting edge will be slightly oxidized.
