Sound Sources
The neareld problem is a source of anxiety with beamforming techniques. We propose a strategy to solve the neareld problem by using a subtractive beamforming technique. The authors earlier proposed a method for noise reduction using paired-microphones. In this paper, the method is improved for neareld sound sources. The proposed method can maintain a high performance regardless of the distance ...
متن کاملSynchronization of sound sources.
Sound generation and interaction are highly complex, nonlinear, and self-organized. Nearly 150 years ago Rayleigh raised the following problem: two nearby organ pipes of different fundamental frequencies sound together almost inaudibly with identical pitch. This effect is now understood qualitatively by modern synchronization theory M. Abel et al. [J. Acoust. Soc. Am. 119, 2467 (2006)10.1121/1....
متن کاملDetection of Submerged Sound Sources
It has been established both theoretically and experimentally (Fig. 1) that sound, when propagating in the ocean, has a tendency to form ribbon like structures some of which can be of relatively high intensity. The scientific objective of this project is to establish the reasons why these ribbons form, to find out what determines their position and lifetimes, and especially how they change when...
متن کاملAttentive Tracking of Sound Sources
Auditory scenes often contain concurrent sound sources, but listeners are typically interested in just one of these and must somehow select it for further processing. One challenge is that real-world sounds such as speech vary over time and as a consequence often cannot be separated or selected based on particular values of their features (e.g., high pitch). Here we show that human listeners ca...
متن کاملAspects of Hearing and Reproduction of Extended Sound Sources and Diffuse Sound Fields
A diffuse sound field was created in a reverberation chamber. Broadband impulsive sounds with different temporal density of the impulses were employed. Tests were performed with listeners in the reverberant chamber as well as with the binaural recordings of the reverberant chamber tests. The results of these tests showed a strong lateral concentration of the auditory events when a low temporal ...
