.jmseabrook writes about the audio designers creating fresh sounds for a new era of electric mobility.
I stood at the curb and listened as our friend climbed into the driver’s seat and slammed the door. I waited to hear the Prius hum into life and move forward. I heard the chatter of sparrows; the distant roar of a leaf blower; and, after a minute or two, the opening of the car door.“I did start,” our friend answered. “I drove down to the end of the block, and then I backed past you and drove up in front of you again.” I felt a cold sense of dread. I thought, we’ve got a real problem.
Without real-world data proving that quiet cars could be dangerous, the National Highway Traffic Safety Administration, the federal agency charged with reducing deaths, injuries, and economic losses on the nation’s roadways, could do nothing. The breakthrough came later in the decade, when the N.H.T.S.A. investigated crash rates for hybrids and E.V.s in incidents involving sighted pedestrians and cyclists, and compared those with crash rates for I.C.E. vehicles in similar incidents.
Many electrical appliances make sounds, although few are scored by famous composers. My family’s seven-piece kitchen ensemble, for example—dishwasher, electric oven, microwave, refrigerator and freezer, electric kettle, and coffee maker—creates a discordant symphony of simple beeps, tones, and chimes of clashing frequencies and rhythms throughout the day to inform us when the machines have begun or completed the particular tasks they were designed for. An acoustic ecosystem it’s not.
When the researchers first began working with Renault, Misdariis told me, the collaborators struggled to find a common language in which to talk about acoustic design. “When a graphic designer says to you, ‘This is a red triangle,’ there is no different interpretation possible,” he said.
