No.You may use a condenser microphone to pick up sounds from the environment. This is a powered microphone, which makes it more sensitive than ordinary microphones.
A lousy old 741 opamp is 44 years old. It is designed for a 30V supply (some do not work if the supply is less than 10V), it is too noisy (hiss) to be a mic preamp and its poor slew rate eliminates half the frequencies we can hear.Then the microphone will transform the sound waves into an electronic signal that is fed to the op amp (i.e 741).
No.The op amp in this circuit will be configured as a single-supply inverting amplifier.
