For over 60 years, Bloom has been experimenting and inventing, recording, distributing and preserving sound in Ottawa. When Hy Bloom was eight his father demonstrated what happens when you join a battery, wire, a buzzer and a push button. From there he was hooked on puttering with radios, microphones and amplifiers.
Bloom holds more than two dozen patents for sound amplifiers.
In the early years of the Second World War, when the army needed a means to advertise its Victory Loan program, they were referred to Hy Bloom. He put together his own carbon mic, scrounged some old theatre speakers, and figured out a way to run it all, with his brother, from his 1938 Ford. Hy Bloom designed and installed and ran the sound system there for some of the best musical acts to come through Ottawa. Two of the more memorable acts include Louis Armstrong, and Maurice Chevalier's performance on the evening of Chevalier's 80th birthday. The occasion was the 25th anniversary of the Canadian Maple Leaf flag.
