International Classification:

H04R 5/00

US Classification:

381 17

Abstract:

Described herein are techniques pertaining to real-time propagation of an arbitrary audio signal in a fixed virtual environment with dynamic audio sources and receivers. A wave-based numerical simulator is configured to compute response signals in the virtual environment with respect to a sample signal at various source and receiver locations. The response signals are compressed and placed in the frequency domain to generate frequency responses. Such frequency responses are selectively convolved with the arbitrary audio signal to allow real-time propagation with moving sources and receivers in the virtual environment.

Abstract:

Methods, systems, and computer readable media for simulating sound propagation are disclosed. According to one exemplary method, the method includes decomposing a scene having at least one object into at least one near-object region and at least one far-object region. The method also includes generating at least one transfer function for the at least one near-object region, wherein the at least one transfer function maps an incoming sound field reaching the at least one object to an outgoing sound field emanating from the at least one object, wherein the incoming sound field is based on a geometric acoustic technique and the outgoing sound field is based on a numerical acoustic technique. The method further includes utilizing the at least one transfer function to perform simulation of sound propagation within the scene.

Abstract:

Simulation-based estimation of elasticity parameters and use of same for non-invasive cancer detection and cancer staging are disclosed. According to one aspect, a method for simulation-based estimation of elasticity parameters includes constructing a 3D model of an object comprising biological tissue, the model having a first shape and an elasticity value. A simulation iteration is then performed, which includes simulating the application of an external force to the model, causing the model to have a second shape, measuring the difference between the second shape and a target shape, and determining whether the measured difference between the second shape and the target shape is within a threshold of error. If the measured difference is not within the threshold of error, the process performs additional iterations using adjusted elasticity or force values until the measured difference is within the threshold of error, at which time the final elasticity and force values are reported. In one embodiment, the elasticity value is mapped to a diagnostic parameter, such as an indication of the possibility, presence, or stage of cancer.

Abstract:

The subject matter described herein includes methods, systems, and computer readable media for synthesizing sounds using estimated material parameters. According to one aspect, a method for sound synthesis using estimated material parameters is provided. The method includes at a computing platform including a memory and a processor, estimating, by the processor and based on a recorded audio sample of an impact on a physical object, one or more material parameters of a physical object for use in synthesizing a sound associated with a virtual object having material properties similar to the physical object. The method further includes storing the one or more material parameters in memory. The method further includes using the estimated material parameters to generate a synthesize sound for the virtual object
