    This course will introduce students to the concepts of physics as it applies to sound and sound reinforcement applications. Topics covered will include basic physical principles underlying sound, music, acoustics, and space.


    This is a fundamental course that meets the standards set for audio programs across the country. However, transferability would be determined by the receiving institution.

    Students attending New Mexico Junior College will be evaluated according to the following grading scale:

    						90 - 100%	=	A
    						80 -  89%	=	B
    						70 -  79%	=	C
    						60 -  69%	=	D
    					 	 0 -  59%	=	F

    Four equally weighted tests will count for 80% of the final grade. A final exam will account for 20% of the final grade. All exams will be announced two class meetings prior. Should a student miss an exam, he/she will be allowed to make it up with the final exam at the end of the semester. Only one exam can be made-up in this way. Students will be allowed to take exams early by making arrangements with the instructor.

    Attendance Policy: Two absences may occur without penalty. Each absence after the first two deducts 2% off a student's final grade. There are no excused absences except for college sponsored activities.


    New Mexico Junior Collegeís institutional student learning outcomes represent the knowledge and abilities developed by students attending New Mexico Junior College. Upon completion students should achieve the following learning outcomes along with specific curriculum outcomes for respective areas of study:


    Upon completion of this degree, the student will have the skills necessary to work as a beginning audio/video/multimedia engineer.


    Upon successful completion of this course, each student will demonstrate through examinations, an understanding of how sound is created, how it travels, how it is measured, how it is heard, and how it can be controlled in the studio or other rooms.


    The instructor will respond to emails and phone calls in a timely manner. Test grades will be posted by the next time the class meets, and the instructor will hand back the tests and go over them in class at that meeting. Students are encouraged to visit the instructorís office any time he is present. An appointment is not necessary.


    The NMJC Police Academy is designed to be run with strict, military discipline. In the interest of maintaining the discipline of that program, Music Technology students should refrain from entering the Police Academy side of the building except to use the restroom. Please avoid loitering in their area or wandering down their halls. At times the Police Academy will be conducting drills in the halls. We ask that you do not interrupt or disturb them in any way. Disruption of the Police Academy by students or recording musicians from Entertainment and Music Technology will not be tolerated and may result in expulsion from our program.


    Students will be held responsible for the information on these pages.

    Academic Honesty
    Each student is expected to maintain the highest standards of honesty and integrity in online academic and professional matters. The College reserves the right to take disciplinary action, up to and including dismissal, against any student who is found guilty of academic dishonesty or otherwise fails to meet these standards. Academic dishonesty includes, but is not limited to, dishonesty in quizzes, tests, or assignments; claiming credit for work not done or done by others; and nondisclosure or misrepresentation in filling out applications or other College records. Cheating or gaining illegal information for any type of graded work is considered dishonest and will be dealt with accordingly.

    Americans with Disabilities Act (ADA) Information
    Any student requiring special accommodations should contact the Special Needs Student Services Coordinator at (575) 492-2576 or by e-mail at

    Attendance Policy
    Attendance is required at every session of each course for which the student is enrolled. When unavoidable circumstances make attendance impossible, students must provide a satisfactory explanation of their absences to their professors. College-sponsored activities are considered excused absences and the appropriate sponsor of those students who will be absent from class will notify professors. Students having absences due to college-sponsored activities will need to make arrangements with the affected classes / professor to take care of required work; however, arrangements for make-ups should be made within a reasonable time frame, usually within one week of the absence. Regarding make-up work, absences due to late registration are considered the same as regular absences.

    Cell Phones/Pagers
    All cell phones and pagers must be turned off when the student is participating in any lecture, laboratory, or other learning activity.

    Classroom Conduct
    The professor is responsible for maintaining a class environment best suited for effective learning. By registering for this class, the student is assumed to have entered into an agreement with New Mexico Junior College and the professor to attend the class regularly and to behave in an appropriate manner at all times. Disruptive behavior may result in the student being removed from the class.

    Food and Drink Policy
    Food items and soft drinks may not be consumed in NMJC classrooms. Students are also discouraged from bringing food and drink items into the classroom even though these items remain in sealed packaging. Bottled water is permissible.

    No Children in the Classroom
    In order to adhere to instructional procedures as well as maintain the safety of children, NMJC’s policy of no children in the classrooms (lecture, lab, etc.) will be followed.

    Offering the work of another as one’s own, without proper acknowledgment, is plagiarism; therefore, any student who fails to give credit for quotations or essentially identical expression of material taken from books, encyclopedias, magazines and other reference works, or from the themes, reports, or other writings of a fellow student, is guilty of plagiarism. Plagiarism violates the academic honesty policy and is considered cheating.

    Smoking/Use of Tobacco
    New Mexico Junior College is cognizant of the health hazards associated with smoking / use of tobacco for the smoker, as well as the non-smoker. In an effort to provide a healthy environment for students, employees, and others who may frequent the campus, NMJC prohibits smoking / use of tobacco inside any campus building or facility.

    Tutoring Assistance
    Free tutoring services are available to all NMJC students through Brainfuse and the Academic Success Center located at the Pannell Library on the 1st floor.

    Withdrawal Policy
    Regular, punctual attendance is required for all classes at NMJC. Although the professor has the right to drop any student who has missed the equivalent of 2 weeks of instruction (based on a 16 week semester) whether itís a face to face, online, or a hybrid course, it is not guaranteed that the professor will drop the student. If the student chooses to stop attending a class, he/she should withdraw from the class by accessing your student account in the T-Bird Web Portal at, or submitting the required paperwork to the Registrar’s Office by 5:00 p.m. on Thursday, April 18, 2019. All students are encouraged to discuss their class status with the professor prior to withdrawing from the class.
