Is there a ceiling there?
Ceiling speakers cannot be installed without a ceiling.
At the beginning of the design process, ceiling speakers (SP) are plotted while looking at the floor plan, but sometimes they are plotted in places where there is no ceiling.
Suppose we have a floor plan like the one shown above.
The lighter colored areas in the image on the right are the corridors where people come and go. If you only look at the plane on the right, you might end up plotting CeilingSP above this corridor, but this may be a rash decision. This is because the floor plan directly above may look like the plane on the left.

This is because the floor plan directly above may look like the plane on the left.
The reason for this will be easier to understand when you look at the two floor plans on top of each other. In short, there is no ceiling above the target floor to which the ceiling SP should be attached. It would be easier to understand if you could see the elevation plan, and the structure was as shown in the diagram on the right above.
How should PA speakers be installed in places where there is no ceiling?

In such a structure, the 2nd and 3rd floor corridors have a ceiling above, so a ceiling SP can be installed.
There is no ceiling above the 1st floor corridor, so installing a wall-mounted SP will be considered. It is a bad idea to not install a SP on the 1st floor and use the ceiling SP on the 2nd or 3rd floor for the users on the 1st floor. These places have noise and reverberation. On the 1st floor, these will interfere with the sound of the SP on the 2nd and 3rd floors. Of course you will hear some sounds, but it will be difficult to make out the content of the announcement. In other words, users on the 1st floor can only hear meaningless sounds. |
