Preparations are
in full swing for the ALMA Winter Symposium, our main
event of the year. In the last newsletter we announced
that exhibitor booking was open. We are pleased to
announce that we already have ten exhibitors signed up -
Loudsoft, Listen, Inc., Dr. Kurt Muller GmbH, KSC
Industries, Phase Design, Klippel GmbH, STEP
Technologies, VoiceCoil, Gras, and Ferrotec. If you have
not signed up yet, don't miss out on this opportunity to
promote your products at the industry's premier
networking event - fill out a booth application form to
secure a spot. Out symposium schedule is taking shape
with two training classes - Electroacoustic measurements
by Christopher Struck, and Peter Larsen's extremely
popular 'Basics of Loudspeaker Design' course. There is
one other training program to be announced shortly. We
have also decided on subjects for our round table and
panel discussions, and lined up four technical papers on
new and exciting topics in loudspeaker design and
analysis. More will be announced in our series of Winter
Symposium news bulletins, and you can always find out
the latest from our web site.

Technical Note - Measurement of
Voice Coil Temperature
Ferrotec
has released a technical note on a new procedure that it
has developed to measure
the voice coil temperature of a loudspeaker as a
function of input electrical power or as a function of
time at constant power. This application note describes
the basic theory behind the measurements and provides
the design of a simple electrical circuit useful for
obtaining the voice coil temperature data in real
time.

Test & Measurement
Special
I
have received updates from many in the loudspeaker test
and measurement business for this special feature -
click on the 'more' links to read the full press release
from each ALMA member:
 Tonwel Audio
Company (China) has
recently released a software-driven compliance testing
machine which can perform a complete test to the ALMA
test method TM-438 - Test Method for Measurement of the
Stiffness of Loudspeaker Driver Suspension. More.
Listen,
Inc.
has recently released SoundMapTM, a
time-frequency analysis program which has applications
in the impulse response measurement of loudspeakers and
analysis of loose particle and rub & buzz defects.
More.
Loudsoft offers the
FINELab™ QC Production Test System was
developed by Peter Larsen, because he was not satisfied
with the measuring system he had been using for many
years. It is simple and reliable and has been designed
to cover his daily working needs and nothing more. It
shows both the frequency response and the impedance of
the tested speaker at the same time and enables the
tested speaker to be compared with a reference curve. More.
Audiomatica
presents the
brand new CLIO 8.0 software, a professional suite to
execute electrical and acoustical measurements under
Windows. CLIO 8.0 is one of the first commercial
packages exploiting Wavelet Analysis for loudspeakers
characterization. More.
 Klippel GmbH has launched a
Scanning Vibrometer (SCN) which performs
non-contact measurement of the mechanical vibration and
the geometry data of cones, diaphragms, panels and
enclosures. It measures mechanical vibration of
the transducer, visualizes the vibration behavior, shows
contribution to sound pressure output, predicts
directivity pattern, separates radial and circular
modes, analyzes actively radiating cone regions and
detects loudspeaker defects. More.
