Hello guys!
For my project I need microphone which can hear sound at least at 1meter distance, can you please guide few of them, what specifications I should look for to buy that?
I have attached two microphones whether that will be good for me or not?
1-
Sensitivity: -68dB ± 3dB (0.56mV/Pa)
Polar Polarity: Unidirectional
Frequency: 50 – 18,000 Hz
Dimension: 185mm
Power: 1.5V Battery
2-
Polar Pattern: Cardioid
Frequency: 40 – 18,000 Hz
Sensitivity: -48dB V/Pa (4.0mV/Pa)
Power requirements: have both options of phantom power and battery power supply 1.5V AA Battery
3-
Polar Patter: Cardioid
Frequency: 30 - 18,000 Hz
Sensitivity: 20mV/Pa
Power requirements: Direct power from input source
Dimension: 13.5 x 45 mm
I am also cautious about the phantom power, I don't want the circuit to be bigger do I need to have pre-amplifier for that?
Thank you very much for your help.
