ASA Officer Elections

Interested in being more involved with ASA? Officer applications are now open!

Being an ASA officer takes typically 2-3 hours every few weeks (depending on the group) and is a great way to meet professors and make industry connections. It also provides tour opportunities (such as Fox Theatre or Spivey Hall) and outreach opportunities to do fun demonstrations with K-12 students.

See the link to learn more about officer positions and to apply.

20 Oct

Speaker: Dr. Aaron Lanterman

Join us for the seminar given by Dr. Aaron Lanterman, “50 Years of Music Synthesis.”

Abstract: “From the modular beasts by Buchla and Moog in the 60s, to the analog polyphonic synthesizers of the 70s, to the digital samplers of the 80s, and back, we will explore the frontiers where clever circuitry and sonic artistry meet, including a live demonstration of a modular synthesizer. It might get loud.”

Date: October 30th, 2014
Time: 4:30 pm
Location: Love 109
Free food is provided as always!

Bio: “Aaron Lanterman is the most interesting professor in the School of Electrical and Computer Engineering at Georgia Tech. He might be the most interesting professor in all of Georgia Tech, but that may be pushing it a little.”

Seminar: New Orleans Airlift

Join us for our second seminar of the spring semester for a glimpse at an amazing project that lies at the intersection of acoustics, art, culture, and architecture. Come hear members of New Orleans Airlift, a team of artists, musicians, and architects from New Orleans, discuss Dithyrambalina, a sonic playground, performance venue and laboratory for musical architecture in New Orleans.

Date: February 14th, 2014
Time: 11 am
Location: IC 107

As always, food will be provided!

Dithyrambalina

A host of international artists, musicians and inventors are creating Dithyrambalina – a landmark village of musical, playable houses. Invented instruments embedded into the walls, ceilings, and floors of Dithyrambalina’s architecture will support boundary-breaking musical performances and inspire wonder, exploration and invention in visitors of all ages. This New Orleans Airlift project is the evolving brainchild of artists Swoon, Delaney Martin, Taylor Lee Shepherd and Jay Pennington in collaboration with over 100 more artists and musicians to date. Last year they debuted THE MUSIC BOX, as a proof-of-concept for their vision. For more about Dithyrambalina, check out their website.

Speaker: Dr. Julien Meaud

Join us for our first ASA seminar of the spring semester! ME professor Dr. Julien Meaud will give a talk about his work on modeling the mammalian ear. See abstract below.

Date: Wednesday January 22nd
Time: 12 pm
Location: MRDC 4211

As always, food will be provided!

Computational Modeling of the Mammalian Ear

Due to the active feedback by outer hair cells in the cochlea, the mammalian ear is a complex sensory system with high sensitivity and sharp tuning in response to low level sounds and a broad dynamic range. Moreover, the mammalian ear can emit sound that can be non-invasively recorded in the ear canal in order to diagnose hearing pathologies. In this talk I will present the development of a computational model of the mammalian ear that couples a multiphysics model of the cochlea and a lumped parameter model of the middle ear. This model can be used as a virtual laboratory in order to test theories of hearing mechanics and to better diagnose hearing pathologies.

Speaker: Dr. Tim Hsu

Join us for our next ASA seminar on musical acoustics! A presentation will be given by former ASA president Dr. Tim Hsu. See abstract below.

Date: Monday October 21st
Time: 12 pm
Location: MRDC 4211

Food is always provided – it will be delicious this time!

Historically Informed Performance and Musical Acoustics

It is a current trend amongst some musicians to attempt to play music in a historically informed fashioned. These performances, that often utilize period specific instruments, musicologically researched performance styles, historical pronunciations, as well as other period specific decisions, are labeled as historically informed performances. However, as musicians and musicologists explore performance practices, the field of historically informed acoustics attempts to study the acoustics of historical spaces and the modeling and simulation of historical instruments. A highly interdisciplinary field, historically informed acoustics is a cross-section between acoustics, music performance, and musicology. This talk explores these musical acoustical topics and gives examples of some extant and non-extant performances spaces and instruments. These examples will include the current state of acoustical measurements in some extant churches in Venice as well include some of the research challenges in this field.

Speaker: Dr. Jennifer Michaels

Join us this Thursday for our final ASA spring 2013 lecture! The speaker will be ECE professor Dr. Jennifer Michaels. Below is a brief description of the lecture topic and her research background.

Guided Wave Structural Health Monitoring with Spatially Distributed Arrays

Ultrasonic waves have the potential to interrogate critical structures for damage, and many researchers are actively considering them for structural health monitoring (SHM) applications. Unlike nondestructive evaluation (NDE), where transducers interrogating a very small region are manually or automatically moved to obtain complete spatial coverage, in situ transducers for SHM are fixed in space. However, the constraints of spatially fixed transducers can severely limit the performance of such an SHM system, particularly in complex structures subjected to variable operational and environmental conditions. In this presentation, guided wave imaging methods are described for SHM using spatially distributed arrays; the context is current and past projects of the QUEST Laboratory at Georgia Tech. Results presented not only demonstrate recent progress but also point out the need for additional research and development efforts so that obstacles preventing widespread adoption of guided wave SHM systems can be overcome.

Date: Thursday, April 4th, 2013
Time: 11:00 am
Location: Love Bldg. Rm 109

Dr. Jennifer E. Michaels is a Professor in the School of Electrical and Computer Engineering at Georgia Tech and is serving as Interim Associate Chair of ECE Undergraduate Affairs. She received the Bachelor’s of Electrical Engineering degree from Georgia Tech in 1976, and began working in the field of ultrasonic nondestructive evaluation at the Hanford Engineering Development Laboratory in Richland, Washington. This work led to her graduate studies in Theoretical and Applied Mechanics at Cornell University, where she earned her M.S. and Ph.D. degrees in 1982 and 1984, respectively, and then spent a year as an IBM Postdoctoral Fellow. From 1985 until joining Georgia Tech in 2002, she worked in industry, first as co founder of a startup company, and later as Manager of Systems Development at Panametrics, Inc., a world leader in the development, fabrication and deployment of custom automated ultrasonic inspection systems. At Georgia Tech she is co-director of the QUEST (Quantitative Ultrasonic Evaluation, Sensing and Testing) Laboratory, where current projects relate to ultrasonic structural health
monitoring and nondestructive evaluation.

Professor Michaels is a member of the Acoustical Society of America and the American Society of Nondestructive Testing, and is a senior member of IEEE. She is currently serving as Associate Editor of Ultrasonics and The International Journal of Structural Health Monitoring. Her general research interests include signal processing, wave propagation, pattern recognition, detection and estimation, data fusion, sensing methods and measurement systems. Current and past sponsors of her work include AFRL, AFOSR, DARPA, HSARPA, NASA, NSF and industry.
