The purpose of the invention is to provide a spirometer useful for determining the specific relationship of the behavior of the volumetric air flow with regard to a sound signal, the control method consisting in the volumetric air flow associated to the sound properties, the development of an air flow generator for emulating the natural or artificial pattern. The processing of transduction, the acquisition and signal are required for determining the specific relationship of the signal and applying the same in the development of a prototype of a digital spirometer. |
