Immediately after starting up, the proxy server executes queries to extract the structured data corresponding to directory distribution information from the distributed directory servers. When a momentary large noise sound is contained in the audio signal, the gain reduced state invoked to suppress the effect of the noise sound is detected, and thereafter if the amplitude of the audio signal has become smaller than the reference level due to the noise sound ending, the gain is increased each period that is shortest among the periods of control employed. Finally, a plurality of solder balls are implanted on the substrate at area outside the second encapsulant.
