ENGINEERING ACOUSTICS
Autumn 2016, Class 34769/34770
Course Syllabus
Lecture Meeting Times: Tuesday/Thursday 12:45pm-2:05pm. Location: Caldwell Lab 109
Instructor: Prof. Ryan L. Harne. Office: E540 Scott Lab. Email: harne.3@osu.edu
Office Hours: Mondays 4:30pm-6:00pm, Fridays 12:00pm-1:30pm, or by email appointment
Prerequisites: ME 3260 System Dynamics and Vibrations, or instructor approval
Disability Information: Any student who feels s/he may need an accommodation based on the impact of
a disability should contact the Instructor privately to discuss their specific needs. The Instructor will
communicate with the Office for Disability Services (150 Pomerene Hall) to coordinate reasonable
accommodations for students with documented disabilities.
Conduct: Students are expected to maintain professional and open-minded conduct throughout the course.
All suspected cases of academic misconduct will be reported to the OSU Committee on Academic
Misconduct. Information on academic misconduct is posted at http://oaa.osu.edu/coam.html
Objectives: The objectives of this course are to
1. Introduce fundamental concepts of acoustical system analysis and design
2. Understand linear wave propagation phenomena in air, including radiation, absorption, and transmission
of sound from and through simple structures/materials and in enclosures/rooms
3. Acquire essential knowledge and skills to effectively participate in engineering noise control practice,
including understanding measurement techniques, prediction methods, and design tools for acoustical
systems
Course Description:
Mechanical vibrations mathematics review. Acoustic wave equation, propagation, and metrics.
Instrumentation for and evaluation of acoustic measurements. Elementary acoustic sources and their sound
propagation characteristics. Acoustics in and between rooms. Applications of acoustics: noise control and
psychoacoustics.
Textbook and Course Notes:
The Textbook used for this course is: L.E. Kinsler, A.R. Frey, A.B. Coppens, J.V. Sanders,
Fundamentals of Acoustics, Fourth Edition, Wiley, 1999. (KFCS). The course material will be
derived primarily from this Textbook. Course Notes will be posted on the Carmen course website.
The Course Notes will be a valuable resource for study and review. Reading assignments will refer
to chapters of KFCS. This textbook is anticipated to be used for ME 8260 "Advanced Engineering
Acoustics".

Course Website: There will be a Carmen website for this course. On the website, Homework assignments,
Course Notes, resource materials, occasional video lectures, and grades will be posted. Students are
responsible for regularly checking the Carmen website for such material.
Homework: There will be six Homework assignments subject to following guidelines. Deviations from the
guidelines will result in points deductions. Guidelines:
 Homeworks are individual efforts unless otherwise noted
 Although homework may be prepared using a word processing software, the homework
submissions must be submitted in paper form and must be stapled in the top left corner
 All Homework submissions must include (i) page numbering and (ii) a header on the top of every
page that includes the following information: Name, name.#, Homework # (where the red text
indicates the appropriate substitution)
 Word processed (i.e. from Microsoft Word) or legible, hand-written assignments are acceptable
 Show your work and indicate solutions by enclosing, emphasizing, or underlining the solutions
 All plots must be generated in MATLAB and include MATLAB code used to generate results
 Label all curves and axes on plots or sketches
 Late submissions will not be accepted without a valid reason.
Software: MATLAB will be used in lectures and will be necessary for many of the Homework assignments.
MATLAB is available in the MAE Department.
Grading Policy:
Students will be graded using the following evaluations which will be developed from the course material
as presented in lectures, in recitations, in the Textbook, on the course website, and from Homework and
Reading assignment material. While the OSU Standard Grade Scheme will be used, the Instructor reserves
the right to make appropriate grade adjustments according to class/student performance.
(30%) Midterm Exam
(30%) Homework. Six homework assignments
(40%) Final Exam (comprehensive)
