JBL CBT Calculator

The Internet is filled with all sort of applications and programs that you could use to make your work easier. One of them is JBL CBT Calculator.

It's a nice precision engineering tool, allowing audio professionals to design CBT Constant Beamwidth Technology line array column loudspeakers into a wide variety of venues.

The application doesn't take long to install and it doesn't come with a complicated setup that you would need to complete before you can actually use it. It sports a clean and intuitive graphical interface with many nice tools at hand.

The CBT Calculator shows the vertical coverage, sound level capability, and evenness of coverage of either one or two CBT speakers, set to various settings, in a room with up to 4 independent listening planes.

This calculator provides the resulting SPL vertical coverage mapping of a proposed design, and computes the frequency response of up to 6 listener locations as well as an SPL summary of the microphone locations over user-defined frequency bands. It shows the sound level projection from the CBT loudspeakers.

Colors correspond to the Sound Pressure Level (SPL) chart to the right of the Coverage Display. This display shows a Sectional View (ie, side view) showing the vertical coverage of the speaker within a room having one to four listening planes.

Up to 6 microphone locations can be defined on the Listening Plane(s). You can drag a speaker to a different location. All CBT models have a Music/Speech switch on them.

It also displays the frequency response (from 100 Hz to 10 kHz) for each of the microphone locations that you’ve places on the Listening Planes in the Coverage Display.
