USE/ADVANTAGE - Provides synchronised light and sound signals with rapid control response. The signals are modulated mainly in the delta, theta, alpha and beta frequencies of human brain waves.doi:DE4241312 A1Michael RemannDE4241312A1 * 1992年12月8日 1994年6月9日 Michael Remann Unterwasser ...
of EP1243849 A modular element for supporting light, sound and image sources (2) and realizing knock-down structures, the element comprising a box-shaped and substantially flat body (1) on which there are provided windows (3) arranged side by side and delimited by respective grooved edges (4...
The sound radiated by an airfoil in the wake of a rod is predicted by means of compress-ible large-eddy (LES) simulation. The LES strategy is based on high-order spectral-like numerical methods to allow the direct noise calculation of the sound sources. Owing to the complexity of the geom...
Indoor noise level is a significant factor for occupants’ health, comfort, and psychological well-being in residential buildings; hence the World Health Organization (WHO) recommends guidelines for residential buildings based on the 24-h sound levels. However, only few studies have examined 24-h ...
The high-light point focus method is presented in the paper in order to get the reference signal. The disturbance sound sources are counteracted in the element level, so that the influence of them is suppressed effectively on the near field underwater acoustic image measurement. The simulation ...

This study focuses on the phonological opposition between the English abstract categories /d/ and /t/ and their contextual acoustic neutralization to the sound [ ], a coronal tap. English phonemes /d/ and /t/ have many acoustically distinct acoustic realizations that are conditioned by the surro...
In the second embodiment, the sound producing component is formed integrally with the toy and has a conical sound chamber with an associated bellows operated responsive to squeezing of the toy walls. LZ Hakim - US 被引量: 21发表: 1976年 ...
Thus, all the sound stimuli were filtered to represent different impact and airborne sound insulation of partition walls and floors in lightweight buildings. It was also hypothesised that total annoyance might be affected by different combinations of structure-borne and airborne sources; thus, ...
