Greeting Electronoobs

Can you please show me how to use sound sensors as ears so that the robot can detect it and follow the maker?  

Thank you

maybe use 2 microphones and each with an amplifier. Connect the output from amplifiers to analog inputs. Then compare which has higher value and turn the robot in that direction.

Keep up!
