This article provides an overview of important measures that are typically listed in mic specification: frequency response, sensitivity, impedance, self-noise level, and signal to noise ratio. Knowing these points might help to choose the best recording microphone for a specific application.
Microphones are the latest device that is very useful in our day-to-day life. These are devices that convert audio into patterns of electrical signals. Today, we see that lots of large organizations are successful by using microphones in many regions of their work. You can visit online stores to purchase the professional recording microphone at an affordable price.
Frequency response measures the way the mic reacts to different audio frequencies. A perfect"flat" response (equal sensitivity) mic would respond equally to all frequencies over the sound spectrum. It generates a more accurate reproduction of sound and produces the purest audio. Typically spec sheets will record frequency response for a range such as"20 Hz to 20 kHz", which means that the microphone can reproduce sounds that fall within that array.
This doesn't explain how correctly different individual frequencies will be reproduced. Some microphones are intentionally designed to react differently at certain frequencies. As an instance, instrument microphones for bass guitars are typically engineered to be sensitive to low frequencies, while vocal microphones are more responsive to the frequency of the human voice.
As a general guideline, condenser microphones have flatter frequency answers than dynamic ones. This implies that if the precision of sound reproduction is your principal goal then the condenser is a better choice.
Microphone sensitivity measures how much power output is generated for a given sound pressure input. The difference is that 94 dB SPL is the normal sound intensity of somebody talking at a distance of twelve inches, while 74 dB SPL will be the exact same speaker an inch away. Although it is very important that you understand how to read / Compare microphone sensitivity (output), the true sensitivity score is generally not a significant factor in mic choice. Typically the design of a microphone for a particular program plays a role when producers determine the right output levels.
