The sound of time and space gives people an understanding of the environment and provides people with a sense of life. In the campus life of students every school day, in addition to the learning listed in the class schedule and the exchange of experiences between peers, the campus atmosphere shapes students' unique common memories. This course leads high school sophomores (who have personally experienced school life for a year) to first find and record sounds that they feel are unique on campus, and then the classroom teacher uses sound editing software to deconstruct the sound elements (frequency, vibration, duration, waveform) The simple concepts of physics and mathematics and the techniques of making music (melody, rhythm, harmony) are finally used by the students to adjust and change the sound effects through the sound editing software audacity according to the original recording of the sounds on the South Girls Campus. The collage is assembled to create an auditory design that is unique to the students' own understanding of the beauty of sound, and the visual picture of the sound spectrogram calculated in the sound editing software is displayed when the work is presented orally.
