Since particle velocity is highly correlated with the direction of arrival of sound, the azimuth of virtual sound source can be estimated from loudspeaker signals based on the equations of particle velocity in two sound fields [1].
Having established and validated the model, it is adapted to form alternative spherical loudspeaker arrays based on Platonic and Archimedean solid geometry and also a number of spherical packing routines.
Launched in 1973, the Isobarik DMS, Linn's maiden and flagship loudspeaker was based on and named for the isobaric loading principle invented in the 1950s.
The proposed algorithm for optimizing the crossover filter bank of a multiway loudspeaker system is based on antenna array filtering techniques [11].
After the band separated, he founded Monster Cable Products in 1979 based on loudspeaker cables he invented and manufactured in his garage.
The next stage, in the tradition of my virtual supermarket foray, was to create an 'audio 3D rendition' of the recorded sounds, using 64 audio channels and bespoke loudspeakers from Salford university based on wave field synthesis.
In the case of coaxial loudspeaker systems [7] and based on axial symmetries (around the axis for the system of Figure 1), the expression of the matrix in (3) used to characterize the directivity index of the system can be simplified to the following formula: (14).
In this paper, a comprehensive numerical formulation of a Transmission Line loudspeaker is presented, which is based in a finite difference approach of the governing equations, including the effects of the absorbing material allocated inside the pipe.
In order to correct the frequency response or the lobbing errors of a multiway loudspeaker system, most solutions [1, 4] are based on delaying the signals sent to the loudspeaker system transducers.
Experimental analysis of the developed DPG, which enables flush mounting of the reference pressure sensors, showed improved amplitude and phase-frequency characteristics in comparison with the previous configuration of the DPG based on two loudspeakers.
To present sounds from angles that were between two loudspeakers, we used equal-power panning based on a sine/cosine crossfade between the two nearest loudspeakers.
