AB  - This article addresses another aspect of transducers with the direct digital to analog conversion, sometimes called digital loudspeakers, which is the radiation impedance. In a transducer array embodying such a system, every value of the acoustic pressure from its dynamic range is radiated by a different number of elementary transducers i.e. different total surface of membranes, driven by the PCM signal. Since the critical frequency depends mainly on the total surface of membranes, an interesting phenomenon appears, i.e. every sound pressure level is radiated with different radiation impedance. As a result, different levels may be radiated differently.
