Description

This free online course on Acoustic Metamaterials and Membranes introduces you to the study of acoustic principles and applications to help control environmental noise. The study of electromagnetic waves and acoustic waves dates back centuries. In this regard, acoustic metamaterials which are materials that are designed to manipulate soundwaves, are of prime importance.

Next, you will learn the mass frequency law and the exceptions to it. You will also learn the Limitations of conventional acoustic materials. You will explore what acoustic metamaterials are and their bulk acoustic properties. You will learn the effective mass densities and principles of the metamaterials. These have the potential to impact areas such as machinery noise control, frequency filtering, speech transmission technology, acoustic imaging and cloaking.

Finally, the course covers the topics such as membrane negative effective mass densities and vibration response. It will introduce you to the different Unit Cell types and the different classifications and effects of them. By studying this course, you will have a distinct advantage in understanding these latest materials and how they can be applied.
