How to Reduce Noise in Microphone Recording

Ensuring a quality recording can be quite difficult, particularly when you’re a rookie in the field of microphone recording. Beginners do it inside a quiet room hoping to capture only the sound that was intended to be recorded. Unfortunately, no matter how quiet that room is, a background noise will always be there. It can be the noise within your vicinity or could be because of the equipment that you are using.

Factors Contributing to Noise in a Microphone Recording

Noise is everywhere. We can’t probably eliminate them, but we can surely reduce them, even in microphone recordings. But before we deal with the actual recording itself, let’s first deal with the factors that might contribute to it.

First, of course, is your environment. You have to ensure that all the doors and windows are closed to reduce the outside noise. Second, when the doors and windows are closed, you need to check the room for possible noise contributors such as fans, televisions, and cellphones, among others. Ensure that all of these equipment are switched off, especially those that might also cause interference.

Did you know that the correct usage of the microphone can also help reduce noise in your recording? Additionally, it is important to check and ensure that all main electrical cables are not running on any audio cable as the electromagnetic force surrounding them may cause interference, too.

Types of Microphones Used for Recordings

Like in any other activity, it is important that we use the right tool, in this case, your microphone, when doing a task, in this case, your recording. To give you an idea, commonly used microphones generally will not pick-up subtle sounds, while the built-in microphones such as those in your laptops can pick-up a lot of unwanted noise.

A dynamic microphone is best used for home studio recording. This is less sensitive and therefore captures less high-frequency background sounds such as noise from fans and room echoes. A cardioid pattern microphone can also be used in a home studio as this type of microphone rejects sound from the rear. You can easily minimize noise by just pointing the microphone away from the noise sources.

Proper Use of Headsets and Headphone Microphones

When using headphones for your recording, make sure that they are tightly plugged into the computer through the microphone jack and not through the audio input jack. You may also try unplugging the power cable, which can also be a source of audio interference, and just use the battery power. If it cannot be prevented, do trial recordings using different power sockets as they do produce noise, too. You just have to choose the one with the least noise.

Accessories for Noise Reduction

Now, when you have ensured that you are in a quiet environment, you are using the right type of microphone, and your cables are not causing any audio interference, but there are still unwanted sounds captured in your recordings, you may want to resort to using some noise-reduction accessories.

A preamplifier helps in the smooth transition of sound between the microphone and other equipment. A power or ground lift adaptor for the power supply of your laptop can also be helpful in reducing static noise. A shock mount placed on your microphone stand can reduce noise from the vibration. And a windshield can also prevent unwanted wind interference.
