Sichuan Yun Hao Electronics, is a professional audio visual professional engineering company in the private theater systems, villas theater systems, bar lighting and sound systems in the industry by customers, the company in the customer first, quality first, continuous innovation science and philosophy, and look forward to working with you, 3D theater system, theater audio system taking into account the large dynamic, bursting with big production sound reduction, etc., use the United States George Lucas's THX-certified 7.1 theater sound system to ensure that the overall sound reduction reached Intonation studio want to express, period effect at home watching movies as a professional theater in general, extremely shocking realism! ! Play equipment using the latest international and now Blu-ray + HD combines data solutions that can access a large number of high-definition movies, CD music, photos, corporate videos. Integration programs can be a family entertainment! Acoustic treatment: a. Soundproofing treatment auditorium floor space in the villa (former garage renovation), on noise requirements are not particularly large, are more than two adjacent bedroom floor. However, in order to avoid when playing theater, the sound pressure is too large to influence others and the outside sound affect the viewing experience, we recommend windows and doors should be soundproof material selection process, such as: vacuum double glazed windows, double wooden doors soundproof steel clip (35db noise should reach above). II. Acoustic processing field data analysis based on 3D simulation (RT60 test result is 1.26 + -0.03) indicates that the environment reflected sound (Reflected Sound) still exists, more US small space THX cinema standard (Small Room) reverberation time should be controlled at 0.3 ~ within 0.6 seconds, the wall using 22mm thick fabric acoustic panels (attract coefficient 250HZ / 0.68) can effectively reduce the reflected sound (echo, reverb). Can effectively control the reverberation time is about 0.46 seconds according to the simulation of the sound field test software * German CARA acoustics of 3D modeling. *:. CARA computer aided room acoustics three processing resonance (resonance and standing waves) due to the presence of a large number of spatial patterns of cavities (beautifully designed product), standing to effectively reduce and control these resonances arising from miscellaneous box wave, must fill a large number of sound-absorbing material within the cavity, the filling density of 55% or less dedicated to 250HZ low-frequency absorption. Must do double cavity structure reinforcement plate 20CM one rung spacing, diagonal bracing 30CM (wooden keel reinforcement must not use metal frame) four. Speaker placement process reference the original auditorium interior design considerations, with hidden speakers placed bits and suspension combination of methods. In front of a pair of front speakers, center speaker and subwoofer with hidden handle, side wall surround, back surround hidden. All hidden speakers placed in wooden frames, filled with sound-absorbing cotton 400g 3M reduce flutter echo. Frame surface using acoustically transparent fabric panels shelter, shade cloth speaker sound transmission through the sound of its performance should reach 16KHz. Design Summary: 1, clear dialogue, even in low-level segment. 2, the front of the stage accurate stereo image of the sound field positioning. 3, surrounded by a strong sense of surround sound field, does not distract the audience's attention. 4,360 degrees seamless sound field. 5, each seat is very balanced tone, particularly low frequencies. 6, wide dynamic range, there is no background noise and distortion. 7, each seat is "emperor." 8, the system is completely transparent, the audience heard only the sound track rather than the speaker.
