A pneumatic vehicle is provided with a chassis, wheels, a compressed air tank, a heat exchanger to heat the compressed air, and an air motor driven by the heated air and connected to at least one wheel. A communication is stored in a database, and comprises a plurality of sub-components. If tp1 is less than tp2, the bit represents a bit value of \u201c0\u201d and if tp2 is less than tp1, the bit represents a bit value of \u201c1\u201d. Each strip has a thickness which is greater than the distance which separates the side edges of the slot in the intermediate portion but which is less than the distance which separates the side edges of the slot in the terminal portion. One exemplary embodiment provides a method that involves monitoring a first temperature outside the deposition chamber and a second temperature inside the deposition chamber. The method includes generating a plurality of early reflections having principal reflection components by considering measured spatial impulse response characteristics of a predetermined sound field, and generating residual reflections of the principal reflection components and adding the generated residual reflections to the principal reflection components of the plurality of early reflections.
