Upcoming Events

Application of Acoustics for Underwater ROVs

Date: 
Wed, 04/29/2015 - 5:15pm - 7:00pm
Location: 
CCRMA Classroom
Event Type: 
Colloquium

Signaling and navigating in the underwater world presents challenges for traditional approaches such as radio waves and light. Both are readily absorbed in water. Light also tends to scatter and reflect over short distances. Sound waves are much more adaptable to use in this world. While they also present challenges – especially absorption and reflection – they can be used effectively over much greater distances in the order of kilometers.

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.

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
This talk gives an overview of ViSQOL – the Virtual Speech Quality Objective Listener. It is a signal-based, full-reference, intrusive metric that models human speech quality perception using a spectro-temporal measure of similarity between a reference and a test speech signal. The metric has been designed to be particularly robust for quality issues associated with Voice over IP (VoIP) transmission. The talk will explore how the original idea for associating visual similarity with spectrogram changes developed. I’ll show results from a full evaluation of the metric against PESQ and POLQA in a range of scenarios, including how it handles VoIP degradations. The research to develop ViSQOL was sponsored by Google Chrome in Mountainview CA.   Bio: Dr.

Guest Lecture: Julia Litman-Cleper. Sound Mappings: Inhabiting virtual geometry through sound.

Date: 
Thu, 04/23/2015 - 5:15pm - 6:00pm
Location: 
CCRMA Stage
Event Type: 
Guest Lecture
The experience of hearing one’s own voice “from the outside,” usually through an electronic device, is often at first described as “weird” or “strange” and jarring. This talk will discuss the role of internal sound and self-referent external sound in relation to proprioceptive processes, or the sense of oneself in physical space.  Sound compositions may have the capacity to change proprioceptive mappings through inducing otherwise unknowable quasi-spatial experience. We will speculate on possible reasons why it may be so. How is it that certain kinds of sound patterns can cause a deviation from what is otherwise normalized expectations of events in time.

Recent progress in efficient physics-based synthesis of string instrument sound

Date: 
Thu, 04/23/2015 - 5:15pm - 7:00pm
Location: 
CCRMA Classroom [Knoll 217]
Event Type: 
DSP Seminar

ABSTRACT

Applications combining digital waveguides, modal synthesis, and finite-difference time-domain modeling will be presented in the context of efficient simulation of string instruments.

The first part of this talk will introduce a technique for modeling bridge admittances and body radiativity profiles from frequency response measurements on guitars and bowed string instruments. The formulation, relying on modal analysis, is then used to construct reflectance and radiativity models enabling efficient simulation of string plucks via digital waveguides.
