Electret microphone signal amplification
This one from Farnell (almost certainly not the one shown in the question) has a clue to the output level: -



That clue is inside the red box I added. It tells you this; if a 1 kHz sound signal of 1 pascal (RMS air pressure) is applied, the typical output voltage level is -41 dBV. And, -41 dBV is 8.91 mV RMS.

To get 3 or 4 volts peak requires amplification of about 280 times.

So, if you don't have a data sheet you are not going to be able to predict the amplification needed without performing a test.


  I just wanted to know that whether there are a typical output voltage
  for these kind of microphones or not.


If it's important enough to know, plough through various data sheets from various suppliers and see what the spread of output levels is likely to be. Or just buy a microphone supported with a data sheet from a recognized supplier as most EEs would.
