From the September 2023 difficulty of Automobile and Driver.

Whether or not it is for a warning chime to seize the motive force’s consideration or piped-in audio designed to provide electrical automobiles an acceleration observe akin to that of an engine, automakers are working time beyond regulation to design brand-specific aural environments.

Creating a brand new and distinct sound is straightforward, however producing one which’s each pleasing and able to relaying the implied message and its significance is way tougher. That is a key purpose why a lot of manufacturers are outsourcing this process to audio professionals.

Lincoln, as an example, employed the Detroit Symphony Orchestra (DSO) to compose and file the informational chimes in its fashions, an concept that stemmed from the purpose of making a hotter and extra human cabin expertise. Jennifer Prescott, former supervisor of car concord at Lincoln, recalled reaching out to the DSO concerning the venture, fearing the musicians would balk on the concept.
