1. A method of providing a sound quality indicator received digital broadcast, comprising the steps of: receiving a digital broadcast digital radio (210), determining the quality of the received digital broadcast based on the received signal level indicator, and a bit error rate of coded digital broadcast received; audio message decoding from the received digital radio; inalozhenie at least one of said first and second audio indicator on the voice message for generating a composite audio signal, said first audible indicator is superimposed in response to a received signal strength indicator is below a predetermined threshold, and said second audible indicator is superimposed in response to said the coded bit error rate exceeding the second predetermined threshold, wherein said first audible indicator of other Cf. eniyu with said second audio indikatorom.2. A method according to claim 1 wherein the blending step comprises the imposition of said audible indicator only if said received signal exceeds a third predetermined porog.3. The method of claim 1, wherein the level of the received signal indicator is below said first threshold in said digital receiver and said first audible indicator is applied to the audio in the second digital post radiopriemnike.4. A method according to claim 1, further includes selectively disabling audio indicator depending on the user input signal in the decree
