2017 Spring semester:

ME 8260 Advanced Engineering Acoustics

The aims of this course are to (i) establish deep understanding of acoustic wave propagation physics and principles, (ii) understand linear wave propagation characteristics, including radiation, absorption, and transmission of sound from and through structures/materials, along waveguides, and within enclosures, (iii) acquire knowledge on computational tools used to investigate acoustic systems, and (iv) explore emerging areas of interest in the acoustical engineering community.

A tentative course syllabus is provided in the link.

2016 Autumn semester:

ME 5194 Engineering Acoustics

An introductory course on acoustics: the physics of sound. Topics include but are not limited to: air-borne wave propagation characteristics; principles of acoustic measurements; fundamentals and practices of architectural acoustics and noise control; human hearing characteristics and psychoacoustics.

A course syllabus is provided in the link.

The course notes are provided in the link.

2015 Autumn semester:

ME 3260 System Dynamics and Vibrations

An extracurricular video project was assigned where the goal was to examine a concept covered in the course (or related to material therein) as observed and applied to a real-world problem. To complete the project, student teams submitted a short video where the project evaluation metrics were the "balance of 'info-tainment' and educational values" and the "integration of analytical and experimental evidence to examine concepts, prove model predictions (as needed), and illustrate discoveries". The resulting videos exemplified students' excellent comprehension of the course concepts and abilities to communicate their knowledge in engaging ways to a non-technical audience.

Some of the video submissions are shown below while others are provided in this youtube collection.

Outreach

2016 Sept. 28. Students from the Metro Early College High School in the DESIGN Learning Center Program visit LSVR with their teacher, Mr. John Thesing. Dr. Harne, Quanqi, Shichao, and Chengzhe share with the Metro team about engineering and science research at OSU in the Department of Mechanical and Aerospace Engineering, and about the specific investigations ongoing at LSVR in acoustics and dynamics. The students get a hands-on experience of folding our "origami acoustics" specimens, learn about bistable structures with two stable shape configurations, and discover how constraints in elastomeric material systems can be used for shock attenuation and diffusion, such as in helmets. Check out the photo slideshow below for a glimpse of the day.

Dr. Harne and Shichao give the broad overview of research at OSU MAE and LSVR.Quanqi chats with the students before the day begins.Dr. Harne discusses the concept of hyperdamping.Dr. Harne describes how strain in oscillating structures can be turned into electrical energy.Students explore the folding acoustic transducers.Dr. Harne and Chengzhe share about the simple physics of guiding acoustic energy.The topic of origami acoustics is great interest for the team from Metro.
