1. Record – with a phone, laptop, or a digital recorder – 10 minutes of any lecture you’re attending.
2. With the help of editing software (such as Audacity [open source]), remove all spoken words from the file. Coughs, laughs, mumbling, etc., may be left.
3. Give the file a title that tells what the lecture was about and submit your manipulated recording.

This protocol explores sounds and silences as educational media, focusing specifically on the educational aspects of sound recording.
In education, sound recordings may be used to support or replace note-taking, to verify what was said during class, or, in case the listener was not present in the lecture, to distribute teaching beyond the confinements of the physical classroom. In other words, they function as tools of remembrance and distribution – two activities that have close ties to the history of education. Recordings are also political. In the U.S., some conservative groups encourage students to record their ‘liberal’ professors in order to ‘expose’ their ideological basis.
However, speech is but one sound of education. The other sounds – the sound of the room, of the furniture, of bodies moving and acting – constitutes the very milieu, a soundscape, where education takes place. How, then, to remember and distribute this milieu? What could we learn from it, what would it mean to study it?

Gina Cruz — Voice Taken Out of ASU Advisor Lecture
This is a lecture I attended while I was in high school about how to set up things related to getting into ASU such as financial aid, majors, orientation, etc. An academic advisor came to my school and set up an informational lecture for people who had gotten accepted into ASU. This lecture is full of useful information about how to apply for scholarships, how to choose a major for college, what housing is like, and when to attend freshman orientation. It was interesting listening to it now that I am already attending ASU. Time flies.
