What Is The Noise Floor Of A Microphone?

1.	What Is The Noise Floor Of A Microphone?
Answer» The noise floor of microphone is defined by the cartridge thermal noise specification. It is important to note that the electrical noise of the PREAMPLIFIER will impact the noise floor of the microphone and preamplifier combination. Other components in the measurement chain, for example power SUPPLIES and data acquisition systems, can also be limiting factors and INCREASE the MINIMAL sound pressure that you can measure.
