manufactured a computer software program that dramatically enhances
sound system design, according to F. Davis Merrey Jr., president of
Altec Lansing Corp. of Oklahoma City.
Altec Lansing, the Oklahoma City subsidiary of aerospace and
defense congomerate Marc IV Industries of New York, was the primary
player in designing the software program AcoustaCADD jointly with
its sister company, Electro-Voice Inc. of Buchanan, Mich.
The Oklahoma City firm manufactures fixed installation
professional sound equipment for upper class hotels, churches,
sports facilities, airports and other public event locations.
"The software program will improve the overall design of sound
systems and help force the market up," Merrey said. "It will also
help with prospecting future clients and help hold existing
Research and development of the software program took three
years and about a $500,000 investment.
Merrey said he anticipates sales from the program of about
$300,000 in 1990. More important than sales, Merrey said, the
software program will bring new technology to customers interested
in a more accurate, efficient way of designing sound systems.
AcoustaCADD is designed to assist architects, accoustical
consultants and sound system designers in defining the
characteristics of the space before installing a sound system, he
A $925 annual license fee will be charged to customers wishing
to use AcoustaCADD, with a $100 fee for renewal. Parties which
choose not to renew the service will still own the property, but be
unable to obtain assistance.
The software program runs under the MS-DOS or PC-DOS operating
systems. It enables a sound system specialist to enter the length,
height and width of the surfaces of an auditorium on a computer
screen. Once a three-dimensional wire frame model of the
auditorium, including the audience, appears on the screen, the
computer will then calculate coverage, of up to 450 loudspeakers, to
provide intelligibility and accuracy of sound for people sitting in
"A series of (AcoustaCADD) engineering design tools, logically,
but loosely connected, enable sound system designers to do a system
design his way," said John E. Lanphere, AutoCADD project manager.
"Most other systems are more structured."
Characteristics of AcoustaCADD include high resolution graphics,
user interface by means of menuing, rather than a graphic icon
system, and well-defined prompts and onscreen instructions, which
enable a casual user to be productive in a short time, Lanphere
