Short Course #2: Acoustic Design of Mufflers

Sunday, June 11th, 2017

Time: 8:00am-12:00pm
Location: TBD
Cost: $100 for INCE members, $150 for non-members

Description:
This four hour seminar provides an introduction to the behavior of mufflers and silencers including a description of the two-port approach to muffler design. The seminar covers the acoustic simulation of muffler and silencer systems and the use of experimental methods to measure muffler performance. Following a review of basic muffler concepts and definitions, the seminar will focus on meeting design objectives such as insertion loss with a specified back pressure requirement. The final topic will cover optimization of muffler design to meet a specified design objective with a specified space constraint. The main focus is on large and small IC-engine intake and exhaust systems, but most of the information is also applicable to any pipe or duct system.

Instructors:
Tamer Elnady, Ph.D., is currently Professor of Engineering at Ain Shams University, Cairo, Egypt, where he also serves as Head of the Ain Shams University Sound & Vibration Laboratory. Dr. Elnady is President of the Acoustical Society of Egypt. An expert in Duct Acoustics, he is one of the developers of SIDLAB Software for the simulation of sound propagation in duct systems and serves industry as a consultant in Europe, USA, Egypt, and the Gulf region in the field of muffler design, noise control, and environmental acoustics modeling. Dr. Elnady received his B.Sc. and M.Sc. in Mechanical Engineering from Ain Shams University and his Ph.D. in Technical Acoustics from the Royal Institute of Technology (KTH), Stockholm, Sweden.

Daniel J. Kato is an acoustical consultant in San Jose, California. Previously, he worked for over 25 years at Cummins Power Generation (formerly Onan Corp.) where his specialties were, acoustical enclosure design, muffler design and product sound quality. He is a licensed Professional Engineer in the state of Minnesota and is Institute of Noise Control Engineering Board Certified. He received his B.Sc. in Mathematics and M.Sc. in Mechanical Engineering from Rose-Hulman Institute of Technology.

 

Short Course #3: Practical Aspects of Acoustical Enclosure Design

Sunday, June 11th, 2017

Time: 1:00pm-5:00pm
Location: TBD
Cost: $100 for INCE members, $150 for non-members

Description:
This is a half day course on the more practical aspects of acoustical enclosure design and modeling of acoustical enclosure performance. Although much information on the subject exists in handbooks and the academic journals, it is often very theoretical in nature and difficult to apply in a practical manner. This course will draw on those sources, addressing the important design parameters related to the propagation of airborne sound through panels, ducts and holes as well as structure-borne sound through solid components. Also discussed are acoustical enclosure models and materials.

The course assumes a basic knowledge of acoustics and noise control. Those benefitting from this course would be engineers and technicians involved in enclosure modeling and design as well as those specifying and purchasing acoustical enclosures for their own machines.

Instructors:
David Herrin is an Associate Professor in Mechanical Engineering at the University of Kentucky. He has worked extensively with industry and has authored or co-authored over 100 journal and conference papers. He completed his Ph.D. in Mechanical Engineering in 2000 from the University of Kentucky and is a licensed Professional Engineer in the state of Kentucky. Over the last 5 years, he has been an Associate Professor directing the efforts of the Vibro-Acoustics Consortium. The Vibro-Acoustics Consortium (VAC) is a collective of over 20 companies that sponsor noise and vibration research at the University of Kentucky. The primary mission of the VAC is to expand the use of predictive modeling in industrial applications.
