Is there any possibility to converting sound energy to electrical energy by using piezo electric material.

It used to be done all the time with the POT device (POT = plain old telephone)

I think Av... is correct,I also don't think old fashioned phones used piezo crystals as microphones or speakers
 
I think the question is more to do with what we mean by 'Energy'. Is it 'Energy' as a detectable signal or 'Energy' in the quantity that could be used as a useful resource.
As has been stated dozens of times before, there is just not enough 'Energy' around, in the form of sound, to provide us with any significant amount as a resource. A few milliWatts (maximum) is just not enough to make a significant difference to our lives.
To live in any conditions where there would be enough sound level to drive any of our equipment would involve wearing ear protectors and doing ourselves physical harm, probably. Do you want to live in the Dartford Tunnel or at the end of a Heathrow runway?
