Technical Data and
Specification Tools
Technical Data
SoundTube Entertainment strives to
provide complete and effective technical
information and data to dealers, engi-
neers and designers. All data are avail-
able from SoundTube Entertainment or
at www.soundtube.com.
Data Acquisition
All performance data acquired at
SoundTube’s Technical Measurement
Center (TMC) are analyzed using a
variety of standard measurement tech-
niques, including Measured Length
Sequence (MLS) and Time Delay Spec-
trometry (TDS). Performance, develop-
ment and data acquisition tools include:
Gold Line TEF 20, CLIO, LMS, LEAP,
and proprietary modeling software.
EASE™ data are acquired through
an automated TEF 20/Outline/EASE™
interface.
