Effects of cognitive load on perception

Date: 
Fri, 05/29/2015 - 11:30am - 12:30pm
Location: 
CCRMA Seminar Room
Event Type: 
Hearing Seminar
How is it that we recognize audio, in impoverished environments?  How does our cognitive state, and the load our brains are suffering under, effect how we perceive and understand audio? Speech gives us a convenient model to talk about syntax, but the same considerations probably apply to music.  While this talk describes a speech paradigm, I believe it applies to all forms of auditory perception. 

   Who: Sven Mattys (University of York, UK)
   What: Effects of cognitive load on perception
   When: May 29, 2015 at 11AM
   Where: CCRMA Seminar Room
   Why: Because perception depends on cognition

Naomi Harte - ViSQOL, An objective measure for speech quality

Date: 
Fri, 05/01/2015 - 11:30am - 1:00pm
Location: 
CCRMA Seminar Room (Top Floor of the Knoll)
Event Type: 
Hearing Seminar
How do humans judge perceptual quality of a signal? It’s easy to measure mean-squared error, but that is not how the brain measures quality—that would be too easy. Instead, we want to look inside the brain to see how sound is encoded. This problem is important as we build more devices that process sound and we need to assess whether they are doing a good job. Naomi’s work addresses the problem when we have access to the original and the modified sound. It’s an improvement over the PESQ and POLQA work, if you are familiar with the area.

Acoustic Source Localization in Wireless Sensor Networks: Model and Numerical Algorithm

Acoustic Source Localization in Wireless Sensor Networks: Model and Numerical Algorithm

Abstract: Jianhua Yuan will present a series of techniques, based upon the energy based acoustic features, to locate a sound source given measurements of the sound field. For wireless ad hoc sensor network applications, energy based acoustic features is an appropriate choice since the acoustic power emitted by targets, such as moving vehicles usually varies slowly with respect to time. In this approach, mathematical models and new numerical methods may be used to yield higher accuracy in terms of source location estimates compared to the earlier method.

Tricking the brain

Most interns don’t deliberately try to deceive executives at their employer’s company, but Dolby intern Jimmy Tobin was asked to do just that.
 
For a reception following a day of meetings for the company’s 90 top leaders, Tobin, a student of symbolic systems at Stanford University, and fellow interns working in the Science Group with Senior Staff Scientist Poppy Crum were asked to create a series of demonstrations of perceptual illusions.

Stanford scientists build a 'brain stethoscope' to turn seizures into music

When Chris Chafe and Josef Parvizi began transforming recordings of brain activity into music, they did so with artistic aspirations. The professors soon realized, though, that the work could lead to a powerful biofeedback tool for identifying brain patterns associated with seizures. Read more here...

The Stanford Ph.D Student Making Human Music with a Laptop

When it comes to music-making, laptops get a bad rap. They're cold, impersonal, inexpressive, and can't summon the warmth of traditional acoustic instruments. Or at least that's one way to look at it. Experimental musician Holly Herndon disagrees — and has spent much of her career exploring the expressive potential of the machines that are now an inseparable part of modern life. Read more here...

CCRMA's Rob Hamilton at Design Night

Our very own Rob Hamilton, along with his partner in crime Chris Platz, was at a recent Design Night at the Autodesk Gallery in San Francisco. Rob and Chris were displaying their gaming-inspired work "Echo Canyon." Read more here.
