I have a condenser microphone that has no any model name or number. As we know condenser microphones need a bias voltage for operation. Some microphones need \$2 V\$[1]. and some need more. As we can not feed microphone more than its \$V_{max}\$, is there any way and measuring method to calculate the appropriate bias voltage of it without having its datasheet?
Edit:
What is the appropriate Resistor to build the biasing voltage?
