Source arrays for directional and non-directional sound generation
In this paper, methods are presented to design an acoustic source array for both directional sound generation and non-directional sound generation. The methods are based on measured transfer functions to be able to take into account different source sensitivities, to use extended sources that cannot be regarded as point sources, and complex geometries modifying the radiation characteristics. Th...
متن کاملThe Sound Port: Development of Abi-directional Sound Transducer
The realisation of a functional Sound Port would be aided considerably if a bi-directional transducer were available. Electrodynamic transducers are capable of being used as the basis of a such a transducer. An analogue circuit model has been established which can be used to simulate both directions of their operation with reasonable accuracy. An 'in progress' design for a method of recovering ...
متن کامل"3DEV: A tool for the control of multiple directional sound source trajectories in a 3D space”
This Paper presents a GNU software (3DEV) developed for the creation, transformation and temporal coordination of multiple directional sound source trajectories in a threedimensional space. 3DEV was conceived as a general tool to be used in electroacoustic music composition, and the data generated by it may be transmitted on a simple and effective way to several spatialisation
متن کاملDirectional sensitivity of neurons in the primary auditory (AI) cortex: effects of sound-source intensity level.
Transient sounds were delivered from different directions in virtual acoustic space while recording from single neurons in primary auditory cortex (AI) of cats under general anesthesia. The intensity level of the sound source was varied parametrically to determine the operating characteristics of the spatial receptive field. The spatial receptive field was constructed from the onset latency of ...
متن کاملBiomimetic Sound-Source Localization
Sound-source localization systems typically comprise free-field microphone arrays. In nature, directional acoustic sensing evolved to rely on diffraction about the head with only two ears. For localization, the brain uses the resultant frequency-dependent acoustic phase and intensity differences between the two ears. We conceive a biomimetic artificial head with microphones placed on its surfac...
