1. With loadspeakers, the entire sound field of the original room must be replicated. 2. Stephen composed the music as well as creating the four channel sound field . 3. A monopole-like sound field is generated by volumetric flow rate oscillations. 4. This results in a non-uniform sound field , unlike the monopole whistle. 5. The uniformity of the measured sound field for this whistle confirmed its monopole-like nature. 6. This includes questions of sound field sampling, synthesis and perception. 7. And similar systems are also proposed to reproduce a sound field in a 3D space. 8. The sound field can be described using physical quantities like sound pressure and particle velocity. 9. The measured sound field was clearly dipole-like ( modified slightly by the plate presence ). 10. The flow over the edge results in an applied force and a dipole-like sound field .
