The indoor overall environmental comfort of part limited spaces is studied in this paper. The operative temperature, illumination, and noise intensity are used as objective parameters in order to evaluate the thermal, luminous, and acoustic environment. The thermal, luminous, and acoustic environment are investigated by using the subjective questionnaire in this experiment, and the function rel...

In this paper, we study methods to enhance the precision of the online estimation process of a recently proposed approach, ensemble speaker and speaking environment modeling (ESSEM), and therefore improve its overall performance. The ESSEM approach consists of two integral phases, offline and online. In the offline phase, an ensemble environment configuration is prepared by a large collection o...

An efficient finite volume approach has been used to develop a three dimensional Helmholtz acoustic solver for complex geometries. This acoustic solver was utilized to obtain characteristic mode shapes and frequencies of a baffled combustion chamber. An experimental setup, including stationary and moving sensors, has also been used to measure these quantities for the same model combustion chamb...

Extracting the coherent component of the ambient noise field propagating between a pair of passive receivers provides a means for passive acoustic sensing of the ocean environment. For instance, the arrival-times structure of the ambient noise cross-correlation time-function between a pair of receivers can yield an estimate of the arrival structure (or wavefronts) of the actual time-domain Gree...

We will demo the features of Sound Lab (SLAB), a softwarebased real-time virtual acoustic environment (VAE) rendering system designed for use in the personal computer environment. SLAB is being developed as a tool for the study of spatial hearing.

This paper focuses on soundscape planning, or acoustic design, in the planning and management of open space in both urban and non-urban areas. It is based on notions, promoted over several decades, that the acoustic aspects of open space can, and should be, subject to design in the same way as are the visual dimensions. The current paradigm for the management of the outdoor acoustic environment...
