You may be good at ‘eyeballing’ a room to determine loudspeaker choice, mounting angles, expected levels and coverage, but how do you convey these elements to your customer? What document do you put into your proposals that shows that you’re not just leaving loudspeaker coverage to chance? Do you encounter proposals that require ‘the successful bidder’ to submit loudspeaker coverage plots from EASE or a similar program?
This course was developed to help you improve your accuracy and success in the area of loudspeaker choice and placement, and to help you express to your clients that you command both the art and the science of sound system design, and are recommending to them the very best system for their needs. This course utilizes two design tools: Trimble’s Sketchup and JBL’s DDA (Digital Directivity Analysis), both of which are free to download and use. Rooms are drawn in Sketchup, then exported to DDA, where loudspeakers* are deployed and tested. As a bonus, the Sketchup model you create may be used for acoustic analysis, to help show your client how acoustic treatment would improve sound in their room. *DDA is not exclusive to JBL products. It uses .CLF (common loudspeaker format) files, which are available for most professional loudspeakers.
