THE INSTITUTEAfter months of building a high-performance hybrid vehicle, a 5,138-kilometer drive across North America, and four days of competition, the University of Victoria’sFormula Hybrid team took first place at the annual  IEEE/Society of Automotive Engineers competitionfor best overall hybrid design.

The contest, which was held this year from 28 April to 2 May, challenges undergraduates to design and build a race car with a hybrid drivetrain. The event has been hosted by Dartmouth College at the New Hampshire Motor Speedway since 2006. This year teams from 20 different schools participated. The vehicles were tested on their acceleration, endurance, maneuverability, and overall design.

Now that recorded sound has become ubiquitous, we hardly think about it. From our smartphones, smart speakers, TVs, radios, disc players, and car sound systems, it’s an enduring and enjoyable presence in our lives. In 2017, a survey by the polling firm Nielsen suggested that some 90 percent of the U.S. population listens to music regularly and that, on average, they do so 32 hours per week.

Behind this free-flowing pleasure are enormous industries applying technology to the long-standing goal of reproducing sound with the greatest possible realism. From Edison’s phonograph and the horn speakers of the 1880s, successive generations of engineers in pursuit of this ideal invented and exploited countless technologies: triode vacuum tubes, dynamic loudspeakers, magnetic phonograph cartridges, solid-state amplifier circuits in scores of different topologies, electrostatic speakers, optical discs, stereo, and surround sound. And over the past five decades, digital technologies, like audio compression and streaming, have transformed the music industry.
