The objective of virtual 3D sound technology is to convey to the listener an accurate impression of an acoustic environment. This is accomplished by conveying a realistic directional impression of sounds. Most of the successful techniques for doing this are based on the head related transfer function (HRTF). In this paper we shall present a new method that creates the desired pressure field using dipole and monopole pressure fields. The object is to recreate locally the pressure field an actual sound source would produce, in a neighborhood of the listener's ears.
