Writing from Austin, TX, the music capital of the world, and having just experienced the SXSW interactive, film, and music festival, I can attest the importance of audio engineer work. With the rise of demand in digital content for advanced interactivity, TV's, mobile devices, and quality of sound, speakers--both commercial and consumer-grade needs research like this. Because hearing also a subjective sense, audiologists and sound engineers have to know how to please both trained ears and the hearing of the masses. With the boom of automotive infotainment (consumer-grade) and even the increase in millionaire/billionaires in the world (high end-sound systems for private jets, etc), calls for higher quality in sound. Audiologists must work closely with architects as they determine the sound flow in various spaces--both corporate and for public enjoyment.
