Shaping Sounds: Innovative Microphone Designs and How They Function

Carleton University

Microphone technology has revolutionized the ways in which sound is captured and shared. At its core, a microphone is a transducer that converts sound waves into electrical signals.

Uncovering the secrets of the world’s first synthesizer (Part II)

Tom Everrett, PhD

Ingenium - Canada's Museums of Science and Innovation

Seventy-five years ago, Canadian physicist Hugh Le Caine began work on a strange, new musical instrument with an equally strange name: the Electronic Sackbut. While you may not have heard of the Electronic Sackbut before, you’ve almost certainly heard of the ubiquitous musical instrument it pioneered: the synthesizer. This is part two of an ongoing Channel series that follows Ingenium’s reconstruction of the 1948 Electronic Sackbut, better known as the world’s first synthesizer. Today we’ll look

A Phone Call from Below the Arctic Ice - The 50th Anniversary of Arctic III Sub-Igloo Phone Call to Prime Minister Pierre Elliott Trudeau

Ingenium – Canada's Museums of Science and Innovation

On December 17, 1972, Canadian scientists on an Arctic expedition made a groundbreaking phone call to Ottawa. The Arctic III expedition, led by Dr. Joe MacInnis, made the call from 12 metres (40 feet) below the Arctic ice in Resolute Bay, Nunavut, (which was, at that time, part of Northwest Territories).

A bushplane, the de Havilland Canada DHC-2 Beaver, on display at the Canada Aviation and Space Museum. A new text panel sits in front of the aircraft: a gray structure with wood-tone side panels and dark metal legs. Its backlit surface presents the name of the aircraft, a selection of images, and interpretive texts. A life-size display of a dock sits to the right, followed by another aircraft and panel.

Small changes can add up to big results! The look-and-feel at the Canada Aviation and Space Museum is evolving. See how “Quiet Updates” are making an impact.

Yours truly must hereby and heretofore apologise for not having written, last month, any text directly involving the activities of the Canada Science and Technology Museum, in Ottawa, Ontario, a sister / brother institution of the dazzling Canada Aviation and Space Museum, also in Ottawa. Mea culpa, mea culpa, mea maxima culpa. Speaking (typing?) of fault, I also have a confession to make, my reading friend. To my great shame, I must admit that I do not have an ear for music. In my distant youth

Cropped photograph of the 1874 ear phonautograph showing the mouthpiece and ear components.

Reconstructing a lost object: can you identify this component in Alexander Graham Bell's 1874 ear phonautograph?

Tom Everrett, PhD

Ingenium - Canada's Museums of Science and Innovation

The ear phonautograph was a macabre instrument. It was built by Alexander Graham Bell and Clarence J. Blake in 1874, and used a surgically-removed human ear—a skull fragment, ear canal, ear drum, and ossicle bones—to visually “write” sound waves. It worked like this: the surgically-removed ear was first attached to the top bracket of the instrument by a bolt driven through the skull fragment. It was then tightened in place with a thumbscrew. When a user spoke into the mouthpiece, located behind

Take one of these pills and your innards will call me in the morning: The digestive saga of… the radio pill

Rénald Fortier

Ingenium – Canada's Museums of Science and Innovation

Ave amice, scribiti te salutant. Knowing how much you like science, technology, innovation, piña coladas and getting caught in the rain, yours truly would like to bring a pill to your attention. Not just any pill, mind you. Nay. A high tech pill. A radio pill. Oooooh. Shiny. Until it came out, that is. Sorry, sorry. One could argue that our story began with American humorist / columnist / actor Robert Charles Benchley. The earliest mention yours truly could find for Benchley’s With gun and

AI-Generated sound therapy for critically ill patients

Corona Guan Wang

Ingenium – Canada's Museums of Science and Innovation

At the start of 2022, I joined Ingenium – Canada’s Museums of Science and Innovation as a research assistant. Ingenium curators Dr. Tom Everrett (Communications) and Dr. David Pantalony (Physical Sciences and Medicine) invited me to write about a research project that I am currently affiliated with called Autonomous Adaptive Soundscape (AAS). The AAS is an intelligent bio-algorithmic system that selects therapeutic soundscapes to relax ICU patients, via application of machine learning and

John D’Alton Woodlock with one of his sons, Peter Woodlock, in front of the family television set, Iberville, Québec, summer of 1949. Arthur Prévost, “Dix ans avant CBFT – À Iberville, on a la TV depuis 14 ans!...” Le Petit Journal, 14 January 1962, A-49.

But sadly, like so many great minds, Québec television pioneer John D’Alton Woodlock was gone too soon – and quickly forgotten

Ingenium – Canada's Museums of Science and Innovation

Greetings, my reading friend, and welcome to another day for you and me in paradise. As you know, there are people on this Earth who leave it far too soon. The passing of such people is all the more regrettable as you and I can name a host of people the planet could very well do without. Especially now. Yours truly would like to discuss with you today of one of those people who leave our little blue marble far too early. John D’Alton Woodlock was apparently born in 1916, in Montréal, Québec. His
