Seminar: “Investigating hearing biomechanics using a physiologically-based computational model”

Speaker: Dr. Julien Meaud

Date: Wednesday, April 13th

Time: 11am-12pm

 Location: Love 109

 

Abstract: The mammalian ear is able to sense faint sounds (down to 0 dB SPL), distinguish between close frequencies (less than 0.1% apart) and operate over a broad range of sound intensities (6 orders of magnitude). These striking functional characteristics are due to the presence of an active feedback mechanism linked to outer hair cell activity in the sensory organ of the inner ear, the cochlea. Failure of the cochlear amplifier due to genetic disorders, ototoxic drugs, sound overexposure or aging causes deafness or hearing loss. Better understanding of how the cochlea processes sounds is needed to better protect hearing, diagnose hearing pathologies and treat hearing loss. In this talk, I will present a multi-physics computational model of the mammalian ear that couples a middle ear model to a finite element model of the cochlea. I will demonstrate that this physically-motivated model is able to simulate the main aspects of the nonlinear response of the cochlea to sounds and can be used to test key hypotheses about cochlear function. Two main questions linked to experimental observations and with both fundamental and clinical implications will be the focus of this presentation: (1) How does direct mechanical coupling between each cross-section of the cochlear partition affect cochlear function? (2)  How do sounds generated by the cochlea propagate to the ear canal?

 

Bio: Dr. Julien Meaud joined Georgia Tech as an Assistant Professor of Mechanical Engineering in August 2013. Before joining Georgia Tech, he worked as a research fellow in the Vibrations  and Acoustics Laboratory and in the Computational Mechanics Laboratory at the University of Michigan, Ann Arbor.

 

We hope to see you there!

Applied Research Lab @ UT-Austin Mini-Talk

Dr. Jason Kulpe, a recent Georgia Tech graduate, will be presenting information on opportunities at ARL. After the short presentation, food will be provided, as always. Information on the talk is listed below:

Applied Research Laboratories at UT Austin Mini-Talk

Speaker: Dr. Jason Kulpe with ARL

Date: Tuesday, September 15th (next Tuesday)

Time: 11am-12pm

Location: MRDC 2405

 

BioThe Applied Research Laboratories of The University of Texas at Austin (ARL:UT) is a research unit that has been associated with the university since 1946. Throughout its 60 year history, ARL has been engaged in a sponsored research program dedicated to improving our nation’s military capability in applications of acousticselectromagnetics, and information technology. As an organized research unit reporting to the Vice President for Research, ARL supports the three traditional roles of a major university: researcheducation, and public service.

 

And of course, free food will be provided (vegetarian options available).

If you will be graduating soon and are interested in a position at ARL, bring your resume and/or CV!

Speaker: Dr. Mark A. Clements

Join us for the seminar given by Dr. Mark A. Clements, “Issues and Solutions in Audio Retrieval”

Abstract: “The problem of retrieving voice and audio from non-transcribed sources is in its infancy compared to text and meta-data searching. Despite recent advances in speech-to-text (TTS) systems, there are many applications where such approaches are not viable. A phonetic-based high-speed keyword spotting technique was developed at GT as an alternative. It enjoyed sufficiently good success that a commercial enterprise (Nexidia) was established to further develop capabilities and applications. Demos will be given and the technology will be described along with interesting new research results and capabilities.”

Date: February 5th, 2015
Time: 11:00 am
Location: MRDC 2405
Free food is provided as always!

Bio: Dr. Mark A. Clements is Professor of Electrical and Computer Engineering at the Georgia Institute of Technology, where he holds the Joseph M. Pettit Endowed Professorship in Digital Signal Processing. His also served as the Director of Georgia Tech’s Interactive Media Technology Center (IMTC) from 1999-2012. He received the S.B. (Bachelor’s), S.M. (Master’s), E.E. (Professional Engineer’s), and Sc.D. (Doctorate) degrees in 1976, 1978, 1979, and 1982, all in Electrical Engineering and Computer Science from Massachusetts Institute of Technology. He is a Fellow of the Institute of Electrical and Electronics Engineers (IEEE), has been a member of the IEEE Speech Technical Committee, has served an Editor for IEEE Transactions on Acoustics, Speech, and Signal Processing, and was elected to the Signal Processing Society’s Board of Governors. Professor Clements is also founder and director of Nexidia, an Atlanta-based speech technology company. Professor Clements’ current research interests involve digital processing of speech signals. This is concerned with such problems as the application of digital speech technology to sensory aids for the hearing impaired and automatic recognition of speech in adverse conditions. Some of the interesting problems arising from these applications include enhancement of speech in noise, formulation of robust perceptual distance measures, and real-time implementation. Dr. Clements also does work in efficient coding of speech signals, auditory modeling for improved speech analysis, speech production modeling, general digital signal processing, and pattern recognition.

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.

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.”

Outreach: Family Science Night

Family Science Night at Hamilton E. Holmes Elementary is this Thursday, October 2nd. We will be carpooling from the Love Atrium at 4:45pm, doing 3 demos from 5:30 to 7 and returning to Love afterward. The family science night event brings kids grades K-5 and their families together to learn about different science topics and we are returning for our second year to bring acoustics toys and demos to teach elementary acoustics concepts. If you haven’t attended an outreach event yet, we will have experienced members to guide the event and teach you how the demos work, and no previous acoustics knowledge is required.
