Passive moving-coil dynamic microphones do not have active components, so they do not have self-noise ratings. Choose A Dynamic Mic With A Humbucking Coil To learn more about condenser microphones, check out my article What Is A Condenser Microphone? (Detailed Answer + Examples).Ģ. Sticking to mics with low self-noise is the way to go if we're looking to reduce microphone noise.įor a deeper read into self-noise, check out my article What Is Microphone Self-Noise? (Equivalent Noise Level).

Any rating above roughly 20 dBA means the microphone will output a noticeable hiss of noise. When choosing a condenser or active microphone, check out the self-noise rating. In fact, signal-to-noise ratio (SNR) ratings are given to active microphones based on their self-noise ratings. Self-noise is defined as the noise introduced into the mic signal via active components (like transistors, vacuum tubes, and printed circuit boards) and as the noise emitted from these components that are captured by the mic capsule. Choose A Condenser Or Active Mic With Low Self-NoiseĬondenser microphones (and other active microphones) have what is known as “self-noise.” Let's discuss each of these methods in greater detail.ġ.

Use A Noise Suppression Plugin In Your DAW.

Use An In-Line Preamp Before The Mic Preamp.

Do Not Run Mic Cables Alongside Power Cables.

Record In Quiet Or Soundproof Environments.

Choose A Dynamic Mic With A Humbucking Coil.

Choose A Condenser Or Active Mic With Low Self-Noise.

Low noise levels separate the pro from the amateur audio recordings and should be strived for by everyone. The amount of noise in a microphone signal can ruin an otherwise perfect sound capture.
