Чувствительность микрофона приводят в dB, но при разных условиях:
- f=1KHz, 0dB=1V/µbar
- f=1KHz, 0dB=1V/pa
Use “Pascal (Pa)”indication of sensitivity as per the recommendation of I.E.C.(International Electro technical Commission).The Sensitivity of “Pa” will increase 20dB comparing with “ubar” indication.
Example: -60dB (0dB=1V/ubar) =-40dB (1V/Pa)
