Hi again,
how I could compare the declared self noise in the Audio Technica
AT-815 with the values declared by Sennheiser for the MKH-70 ?
AT-815
Open Circuit Sensitivity
PHANTOM: -38 dB (12.5 mV) re 1V at 1 Pa
BATTERY: -39 dB (11.2 mV) re 1V at 1 Pa
Signal to Noise Ratio
70 dB, 1 kHz at 1 Pa
MKH-70
Sensitivity in free field, no load (1kHz) : 50 mV/Pa
Equivalent noise level : 5 dB
Equivalent noise level weighted as per CCIR 468-3 : 16 dB
