A Beam Tracing Approach to Acoustic Modeling for …

    https://www.cs.princeton.edu/~funk/sig98.pdf
    A Beam Tracing Approach to Acoustic Modeling for Interactive Virtual Environments Thomas Funkhouser, Ingrid Carlbom, Gary Elko, Gopal Pingali, Mohan Sondhi, and Jim West Bell Laboratories Abstract Virtual environmentresearch has focused on interactive image gen-eration and has largely ignored acoustic modeling for spatialization of sound.

Beam-tracing model for predicting sound fields in rooms

    https://asa.scitation.org/doi/10.1121/1.2011152
    This paper presents the development of a wave-based room-prediction model for predicting steady-state sound fields in empty rooms with specularly reflecting, multilayer surfaces. A triangular beam-...

    Heat, Light, and Sound Research, Inc., San Diego, California 92130, USA (Received 10 January 2019; revised 23 May 2019; accepted 30 May 2019; published online 1 October 2019) Beam tracing is an extension of ray tracing that constructs beams around the central rays radiating from a source. Typically, a fan of such beams is used to represent a ...

The adaptive beam-tracing algorithm: The Journal of the …

    https://asa.scitation.org/doi/10.1121/1.428427
    The most popular models to predict sound propagation in architectural spaces involve the tracing of rays, images, or beams. Most current beam-tracing methods use conical or triangular beams that may produce overlaps and holes in the predicted sound field. Hence a new method has been developed whereby the shape of reflected beams is governed by the shape of …

Accelerated Beam Tracing Algorithm - Aalto

    https://users.aalto.fi/~laines9/publications/laine2009aa_paper.pdf
    ing. Beam tracing algorithms have been used to calculate these paths efficiently, thus allowing modeling of acoustics in real-time with a moving listener in simple, or complex but densely occluded, environments with a stationary sound source. In this paper it is shown that beam tracing algorithms can still be optimized by

Beam tracing - Wikipedia

    https://en.wikipedia.org/wiki/Beam_tracing
    Beam tracing is an algorithm to simulate wave propagation.It was developed in the context of computer graphics to render 3D scenes, but it has been also used in other similar areas such as acoustics and electromagnetism simulations.. Beam tracing is a derivative of the ray tracing algorithm that replaces rays, which have no thickness, with beams. Beams are shaped like …
