Welcome to inquire! Contact: Lo. Hall sound system design goals: XXX unit roundtable conference hall and room flat rectangular, with a total area of ??about 175 square meters, has more than 150 seats were designed. According to the actual situation of international academic conference hall sound system, sound quality, noise, noise control and other aspects of interior architectural acoustic design. Natural sound, giving priority to meet the loudness of the conference under the premise, clear voice when using small and medium music, theatrical performances when the fullness of the sound. To make the hall sound stereo sound field uniformity, no echo and acoustic sound aggregation defects BOSCH audio and lighting engineering, combined with the building structure YAMAHA sound engineering design, the use of acoustic principles and computer-aided geometric design, determine the spatial location of each interface and acoustic hall surface nature. The main task of body design is the use of acoustics make diffusion designed to give the audience enough early reflections coverage, and early reflections evenly distributed, large coverage. Making body auditorium rich, beautiful and practical. In general, short reverberation time can improve the clarity of the language, a long reverberation time can increase the fullness of the music. We believe that the sound system should first ensure that the primary purpose of the language definition, taking into account the music / video usage requirements. So before making sound reinforcement system design must be in a particular reverberation time basis, only under certain conditions on the auditorium reverberation time of "acoustic characteristics of indicators" design is a scientific and accurate, which is why we sound design focus. The compositional device of professional sound reinforcement equipment: professional sound reinforcement equipment by (1) monitor speakers, amp, subwoofer, EQ, reverb, effects, delay, compressor, limiter, divided sound, noise gate, CD player, tape deck; numerous equipment (2) DVD players, projectors, pitch shifter, song, headphones and other components. ; (3) monitor mixers, powered mixers, portable mixers, power amplifiers, dynamic microphones, condenser microphones, wireless microphones, speakers. For example: a terminal entire speaker sound system, and its role is to convert electrical energy into corresponding audio acoustic energy, and it is radiated to space to. It is the sound system is extremely important part of BMB sound engineering solution because it bears to convert electrical signals into acoustic signals for the human ear to listen directly to such a critical mission, it is to deal directly with human hearing, and hearing people are very sensitive and complex sound timbre has a strong ability to distinguish. Because the human ear is the subjective experience of sound evaluation of a sound system sound quality is most important criterion, therefore, can be considered, the performance level of the speaker playback quality of a sound system that plays a key role.
