    Class Objective:
    The students obtain sufficient background and technical knowledge to understand contemporary issues in musical acoustics and audio technology.
     
    Course Outcomes:
    At the conclusion of EELE 217, students will be able to:
    1. Demonstrate a practical understanding of the relationships among frequency, wavelength, spectrum, and musical pitch for sounds in air.
    2. Express and knowledgeably discuss the acoustic principles of common musical instruments such as strings, winds, and percussion.
    3. Show an awareness and understanding of sound reflection and absorption behavior in small and large rooms.
    4. Describe the characteristics of the human hearing system and the human vocal system.
    5. Show a basic familiarity with the components and characteristics of audio electronics (microphones, speakers, CD/DVD players, etc.).

    Grade guarantee:  point percentages for course letter grades will not be higher than indicated by the following scale:

    A- = 90%
    B- = 80%
    C- = 70%
    D = 60%
    F = 59%

    A grade of F will also be given automatically if the midterm or final exam is not taken, regardless of the student's aggregate score total.
