On 12 December 2003, the US EMC Standards Corporation, in association
with ANSI ASC C63, held its second workshop on ANSI C63.19 that
provides the test procedure for measuring EMC between hearing
aids and cellular telephones. Eighteen attended the workshop held
in a laboratory environment provided by ETS-Lindgren at their
Cedar Park facility. The attendees represented cellular phone
manufacturers, wireless service providers, university researchers,
and independent testing organizations.
This workshop was focused on witnessing the actual test procedures
as well as a review of the test standard. Stephen Berger (TEM
Consulting), Don Heirman (Don HEIRMAN Consultants) and Mike Sacha
(Starkey Labs) were the instructors. They addressed not only the
present C63.19 but also proposed changes that will be balloted
in ANSI ASC C63 in 2004 and how they will be implemented during
the laboratory testing time that afternoon. The added importance
of this workshop was that the ATIS (Alliance for Telecommunications
Industry Solutions) and their Incubator Solutions Program for
Hearing Aids required those who will be participating in their
cellular phone testing program to have a representative at the
workshop to ensure that they witness the nuances of the test protocol.
Based on the end of the workshop questionnaire, the attendees
felt that the workshop met their expectations and that they had
a greater appreciation of the standard. Various photos were taken
of the days events. Be sure to check them out at the end
of this article.
