Both AAA and ADA (Recreational Audiology Committee) have been involved in
presenting various topics regarding RA. Some excellent sources in the field
include Jane Thebo, N. Kansas City; Dave Cieliczka, Concord, NH; Michael
Santucci, Chicago; Ken Stockdell, Murfreesboro, TN; James Rippy, N. Little
Rock, AR; and Bruce Vircks, Des Moines, IA. They all took part in a AAA
workshop on RA back in 1994 and I had the pleasure of interviewing them.
Others include Gary Gordon (fit the three U.S. Olympic medalists with
shooters plugs!) at Insta-Mold and Earl Harford at Starkey.
Fairly recent articles on the subject can be found in both Hearing Review
(May 1994, p. 36-38) and Hearing Journal (May 1995, p. 13-22).
