Hearing Seminars

CCRMA hosts a weekly Hearing seminar. All areas related to perception are discussed, but the group emphasizes topics that will help us understand how the auditory system works. Speakers are drawn from the group and visitors to the Stanford area. Most attendees are graduate students, faculty, or local researchers interested in psychology, music, engineering, neurophysiology, and linguistics. Meetings are usually from 11AM to 12:30 (or so, depending on questions) on Friday mornings in the CCRMA Seminar Room.

The current schedule is announced via a mailing list. To be added to the mailing list, send email to hearing-seminar-request@ccrma.stanford.edu.  If you have any questions, please contact Malcolm Slaney at hearing-seminar-admin@ccrma.stanford.edu.

  • Brain oscillations underlying sensory binding and perception

    Just how is information represented in the brain?  We're all used to rate codes---a neuron fires when it sees something that excites it.  The rate of firing is proportional to how good a match the input is to to the neuron's model. But there is strong evidence that higher-level concepts are encoded with some sort of oscillator, perhaps around 40Hz.  Bernhard will be talking about how MEG and EEG can be used to measure this activity.  Do brain oscillations explain how we group sounds as we parse the auditory world?

    We've got rhythm!  But how?

    I'm pleased to introduce Joel Snyder to the CCRMA community. Joel is studying the mechanisms we use to track rhythm. We can bop to either a visual or an auditory rhythm.  But do the two modalities use the same mechanism, or do they track their rhythms separately? How do the clock(s) work?

    Cochlear implants are pretty amazing.  Profoundly deaf patients can hear if you squirt periodic bits of current into their cochlea. Yet, the current implants are pretty crude.  There are not many channels of information to represent the full richness of human sound.

    While we aren't conscious of how we do it, we humans have an uncanny ability to sense the size of the room from how it sounds. How is this done, and how can we teach a machine how to do it? Nils Peters is an auditory scientist at Berkeley, and he's been studying this problem. I think it's interesting for two reasons: 1) reverberation and our perception of it is an interesting problem, and 2) it is important for our machines (i.e. phones) better understand our auditory environment.

  • Your Attention Please: Three important aspects of auditory attention

    Date: 
    Fri, 11/30/2012 - 1:15pm - 2:30pm
    Location: 
    CCRMA Seminar Room
    Event Type: 
    Hearing Seminar

    At the next CCRMA Hearing Seminar, I'd like to talk about recent work on auditory attention. As many of you know, I'm very interested in how our brains process sounds in complicated environments. Our ability to understand any speech in a noisy cacophony is known as the Cocktail Party Effect. We still don't have good models of how are brains do this task, but an important component of the process is certainly attention.

    I'm very happy to announce that JJ Johnston, one of the principle forces behind the MP3 standard, will be leading the discussion at this week's Stanford CCRMA Hearing Seminar. JJ is widely known and respected for his wide-ranging work and thoughts on the perception of audio. He is only mildly opinionated.

  • Prof. Takako Fujioka on Cortical Signatures of Melody and Rhythm Processing

    Date: 
    Fri, 10/05/2012 - 1:15pm - 2:30pm
    Location: 
    CCRMA Seminar Room
    Event Type: 
    Hearing Seminar

    I am pleased to (re)introduce Takako Fujioka to the Hearing Seminar. She spoke a year or two ago at CCRMA, and is now the newest member of the CCRMA faculty. She's interested in studying how our brains respond to music by measuring non-invasive signals such as those from EEG and MEG.

  • Bernhard Ross - Neuromagnetic studies of auditory brain function

    Date: 
    Tue, 09/25/2012 - 1:15pm - 2:30pm
    Location: 
    Seminar Room
    Event Type: 
    Hearing Seminar

    I'm happy to introduce Bernhard Ross to the Hearing Seminar community.  Bernhard uses MEG (magnetoencephalography) to study the response of the brain to auditory stimuli.  He'll be talking about his work to understand concious perception, and how they change with aging and injury.

  • Mike Mandel (Audience) - Reverberation is all around us, and yet little is understood about its effect

    Echo, echo, echo, echo, and it's all reverberation.  It adds a lot of richness to our lives.. **and** it makes it really hard for machines to understand speech.

    Ahh, pitch.  One of our favorite topics at the Hearing Seminar.  It seems like a simple problem... we know what pitch is, right? But it's not so simple, and modeling pitch still reflects one of the biggest controversies in auditory modeling.  Just how is it that we assign a pitch to a sound? The spectral and the temporal people have been fighting for years.
