CHAPTER 7: SYSTEM DESIGN AND INTEGRATION TOOLS
Meyer Sound offers two comprehensive tools to assist with
the acoustical and functional requirements of system design
and optimization. This chapter introduces you to MAPP
Online Pro, Meyer Sound’s patented online acoustical pre-
diction tool, and SIM 3, a comprehensive system for mea-
surement and analysis.
MAPP ONLINE PRO
MAPP Online Pro is a powerful, cross-platform, Java-based
application for accurately predicting the coverage pattern,
frequency response, impulse response, and maximum SPL
output of single or arrayed Meyer Sound loudspeakers.
Residing on your local computer, the MAPP Online Pro client
lets you configure Meyer Sound loudspeaker systems and
define the environment in which they will operate, including
air temperature, pressure, humidity, and even the location
and composition of walls. CAD (DXF) files containing
detailed venue information can also be imported.
Whether planning for fixed installations or tours with multiple
venues, sound system designers can use MAPP Online Pro
to accurately predict the appropriate loudspeaker deploy-
ment for each job, complete with coverage data, system
delay and equalization settings, rigging information, and
detailed design illustrations. MAPP Online Pro’s accurate,
high-resolution predictions ensure that systems will perform
as expected, thereby eliminating unexpected coverage
problems and minimizing on-site adjustments.
The key to the accuracy of MAPP Online Pro’s predictions is
its exhaustive database of Meyer Sound loudspeaker mea-
surements. Performance predictions for each loudspeaker
are based on 360 1/48th-octave-band measurements taken
with a SIM audio analyzer in the Meyer Sound anechoic
chamber. The extraordinary consistency between Meyer
Sound loudspeakers guarantees that predictions from
MAPP Online Pro will closely match their actual perfor-
mance.
MAPP Online Pro predictions are requested by the client
software and sent via the Internet to the high-speed Meyer
Sound servers where high-resolution (magnitude and phase)
polar data is processed with sophisticated acoustical pre-
diction algorithms. The resulting predictions are then
returned to and displayed on the local computer running the
MAPP Online Pro client software.
MAPP Online Pro Applications
With MAPP Online Pro, you can:
■ Simulate different loudspeaker configurations to refine
system design and zero-in on the best coverage for
intended audience areas
■ Monitor loudspeaker interactions to locate destructive
interferences so that loudspeakers can be re-aimed and
repositioned as necessary
■ Place microphones anywhere in the sound field and pre-
dict their frequency response, impulse response, and
sound pressure
■ Determine delay settings for fill loudspeakers
■ Try out virtual Galileo equalization to determine optimum
real-world settings for the best system response
■ Automatically calculate load information for arrays to
determine rigging capacities, front-to-back weight distri-
bution, and center of gravity
■ Generate and export system images for client presenta-
tions
