CSC is a general sales estimation and engineering tool for selecting ceiling speakers. This free utility program helps select the proper JBL ceiling speaker to use for various applications, based on desired music level or background noise level.
For music systems, the goal is to achieve the proper level of background or foreground music, as
determined by the application type. For paging systems, the goal is to achieve proper intelligibility by
allowing the level of the paging to exceed the ambient sound level by at least 10 decibels, which is the
generally accepted requirement for achieving proper speech intelligibility.
