Configure the power of the ceiling speakers and the layout of the ceiling speakers according to different venue environments. It is necessary to consider the location of the listeners in the entire venue, such as whether they often move, stand or sit more, and the entire venue environment Some factors such as the size of the background noise. The sensitivity level of the ceiling loudspeaker is between 88~93dB; the rated power is 3~10W. Calculated by 90dB/8W, the sound pressure level at 8m away from the speaker is about 81dB. The above calculation does not consider the contribution of the early reflection sound group. Indoors, the contribution of early reflected sound groups and adjacent speakers can increase the sound pressure level by about 2 to 3 dB. According to the above approximate calculations, in venues with ceilings no higher than 3m, ceiling speakers can be arranged evenly at a distance of 5-8m from each other. If you consider background music without considering emergency broadcasts, the distance can be increased to 8-12m.
