The Specs of a Microphone Described in a Simple Manner

A microphone is a transducer, which transforms the vibrating air straight into electrical signals. The operates of diverse microphones vary due to their unique designs and the function they serve. Thus, it is essential for you to study the specs just before purchasing a microphone. Next are some basic terminologies, which will aid you a good understanding of the microphone specs:

1. Sensitivity: Sensitivity corelates to an expression of microphone's electric output whenever it is placed in a particular sound field and in a specific sound pressure. The sensitivity is mentioned in dBV/Pa or in Volts/Pa.

2. Self-noise: All microphones have a noise floor. The noise through the microphone is induced due to existence and movement of air molecules. This noise specs is expressed as equivalent noise level.

3. Frequency Response: It pertains to the manner in which a microphone responds to sounds of diverse frequencies. A flat frequency pattern suggests that the microphone is equally sensitive to sounds of all of frequencies. This kind of frequency pattern indicates a more accurate sound. Condenser microphones have got flatter frequency response pattern and are therefore more favored.

4. Impedance: It measures sum of opposition that a particular microphone contains for alternating current such as audio signal. Impedance is blended result of resistance, inductance and capacitance on a signal. High impedance microphone are cheaper when compared to medium and high-impedance microphone. On the other hand, high impedance phones do not work well whenever connected to long distance cables. Low impedance microphones are of good quality and show much better outcomes.

Because you are now know diverse terminologies related to microphone technical specs, you can certainly now acquire a microphone that best suits your needs.
