Rosenthal's After-School Atelier middle school course, Acoustic Ecology and Soundscape Recording, exposed participants to a wide range of ideas, techniques and technologies for focusing and sensitizing aural awareness of the world. Listeners consider how enhancing this aural awareness can alter their relationship to the urban environment and what impact human sound-making has on that environment. Rosenthal's students developed self-reflective aural archives using the sounds of their homes, neighborhoods, families and friends.
