Office Hours: MW 1:40-2:55, outside of these hours by appointment

 

Lecture: MWF 11:00-11:50 Room 101  WSC

Laboratory: 1:40-2:55, Tuesday/Thursday Room 107 WSC

Prerequisite: SCI 105

General:

 

     Physics and music, a strange mixture?  We will examine music and sound from a scientific point of view.  Our discussion will be one of waves and frequencies, as well as notes and scales.  By the end of the class you will think of music in a different way.  You will be familiar with sound waves, propagation of sound, frequency, harmonics, waves on strings and in tubes, effects dues to the listening environment, perception  and synthesis of music.  This is not an intensely mathematical course, but some algebra is required.  We shall encounter logarithms, for example, in our study of loudness.  You should have a calculator capable of calculating logarithms (log, ln) and raising numbers to a power (Yx).

 

Grades:

 

            Your Final class grade will be derived from the following percentages

                        Average of 2 Tests (55%)

                        In-class Quiz (15%)

                                Laboratory Experiments (30%)

 

You will not be graded on a “curve”.

 

Tests: Make-up exams will only be given to students with valid excuses as defined by the university handbook (illness, emergency, class trips with prior notification).  The make-up exam may be harder or easier than the regular in-class exam.  Any disputes concerning a test grade must be resolved within one week from the time the tests are returned or from the time the grades are made known to the class.  Any grade disputes after this time limit will not be considered under any circumstances.  Partial credit will be awarded depending how many steps were done correctly in a multi-step problem.  The amount of credit will be at the discretion of the instructor.

 

Quizzes: There will be a 5-10  minute quiz one class every week.  This quiz will cover any material discussed in class up to that point of time.  Make-up quizzes are subject to the same conditions as make-up tests.

 

Homework:  Homework will not be graded, but it is suggested that students work all the homework problems.

 

Laboratory Reports:  Laboratory reports are to be the individual work of the student.  You may work together with your lab. partner or other students, but the report must be written by you, and you alone.  The format of the reports will be explained in the laboratory class.

 

All work for which a grade is received, must be the original work of the student without aid or assistance of another party, or any printed and or electronic data/information. Failure to follow these policies will result in an automatic grade of “F” for the course.

 

Cell phones and Pagers: Out of courtesy for all those participating in the learning experience, all cell phones and pagers must be turned off before entering any classroom, lab, or formal academic or performance event.

 

Eating in class:  Please do not eat in class.  I do not mind if you drink, without drawing attention to yourself.

 

Sleeping in class:  Please do not sleep in class, you will be asked to leave.

 

The College’s academic misconduct policy will be followed.

 

Reasonable accommodation will be provided for this course as required under the provisions of the American’s with Disabilities Act and subject to the criteria and procedures used by the Student Development office.

 

Students who believe that they possess disabilities for which accommodation is required must so inform instructors immediately after the first class meeting, indicating the nature of the disability and the sort of accommodation needed.  If you believe that you possess a

disability for which reasonable accommodation must be made, you must consult with the instructor immediately after the first meeting of this class, reporting both the nature of the disability and the nature of the accommodation requested.  If it seems advisable, the instructor will refer you to the appropriate office for documentation of your disability and evaluation of your request for reasonable accommodation.  If you do NOT consult with the instructor about any disability claimed and accommodation sought, your failure to do so will constitute a waiver of any claim of disability and request for accommodation on your part.
