线性阵列的核心技术是全频声耦合技术,决定整个线性阵列的工作效率。每增加1倍相同功率的音箱,声压级增加4倍,否则,就会因干涉而抵消,还不如不增加1倍功率,特别是高频。举例说明:PROSO HB1线性阵列的高音只用1个1时的单元,通过声耦合,每增加一倍功率声压级增加到原来的4倍(6dB),在100m以外10～16kHz还很清晰。因此,声耦合技术对广场扩声产生极其重要的作用。
The core technology of linear arrays is full-range acoustic coupling, which determines the efficiency of the entire linear array. For each additional 1 times the same power of the speaker, the sound pressure level increased 4 times, otherwise, it will offset due to interference, might as well not increase 1 times the power, especially high frequency. For example: The treble of the PROSO HB1 linear array is increased by 4 times (6dB) for every doubling of the sound pressure level by acoustical coupling with only one unit at 1 o’clock, and is very clear at 10-16kHz at 100m. Therefore, the acoustic coupling technology plays an extremely important role in the square sound reinforcement.
