Welcome to


Sound Masking &

Speech Privacy  Systems


There's something to be said about Experience. AVLELEC was established May, 1989 in Lincolnshire, IL. Our first client was Moore Business Forms, Lake Forest, IL. Moore was bought out by R.R. Donnelley, and we are still doing business with R.R. Donnelley to this day.


Our background is SOUND - Patrick McAllister has been involved in the Professional Sound Business most of his life - he has designed and installed systems for Corporate, Government, Performing Arts, Stadiums, Concert Halls and more. He studied Soundmasking with one of the inventors of Soundmasking - White Noise, Pink Noise, Brown Noise -- Analyzation, Db Levels - Speech Privacy.. all key words - and we know what they mean, and how to implement them.


Patrick started Audio Tech Systems, Denver, CO. in 1979. Some of his more prominent installations were the Interim Sound System at Mile High Stadium ( Home of The Denver Broncos ) in the early 80's, Boulder's Coast, Club LA, Westiminster, Atchison Topeka and Santa Fe Railway, Denver.
