Meeting Highlights location of the
November, 17th meeting of the Chicago Section. In 2004, Shure completed construction of
its 65,000 square-foot, two-story Technology Annex, which houses equipment and facilities
for engineering research and development, new product development, quality, service, and
manufacturing support. About 65 attendees were treated to a presentation and
tour of the Annex by a
team of Shure AES members. The meeting
started with a presentation on Shure�s 80-year
history, including the product line. The attendees
then divided into several groups and were rotated through a series of demonstrations, each
highlighting different facilities within the Annex. One stop was the Performance and
Listening Center (PLC), a �building within the building� that includes a
studio for recording
and live product testing (vocal both, large live room, and control room) and
a dedicated theater for
critical listening. Three presenters discussed and demonstrated the facility construction,
the recording and editing of listening test samples, and sound quality
evaluation method. Acoustic
Anechoic Chamber The groups were
taken inside one of the two acoustic anechoic chambers, which are used primarily for microphone
testing. Frequency and polar response testing was demonstrated. The inside if the RF
anechoic chamber, used for product emissions and immunity testing, was also shown. The attendees
witnessed the operation of the H.A.L.T (highly accelerated life test) chamber first
hand, where a sample product was subjected to extreme temperature and
vibration in order to
quickly reveal any potential reliability issues. Drop tests and tensile tests
were also demonstrated,
and the various chambers for temperature, moisture, and salt fog testing were shown and their
purposes explained. There was
clearly a buzz in the air as the attendees mingled in the lobby after the
tour, appreciative of the rare
opportunity and their hosts� hard work. RF Anechoic
