Jens Ahrens
Jens Ahrens är docent vid avdelningen för teknisk akustik och leder forskargruppen audioteknik. Hans huvudsakliga forskningsintressen rör sig inom området rumsligt ljud. Framförallt arbetar han med de tekniska aspekterna av rumslig ljudupptagning och auralisering genom användningen av högtalar- och mikrofon-arrayer samt med den psykoakustik som hör därtill. Rimlig eller till och med autentisk auralisering av ljudscener är ett viktigt verktyg för att undersöka effekterna av ljud på människor, täckande hela skalan från urbant buller till musikupplevelse.
