I’ve talked about how to minimize noise in your podcasts by using different equipment and tweakingthe usage of these equipment. But one factor that also plays a big part in the production of noise in recordings is the environment itself.
Look around the room where you record your podcasts. Most likely you will identify things inside the room that produce noise that can be picked up by your microphone. For example, the air conditioner emits a hum that can be an annoying background noise. Turn it off when recording and just turn it back on when you’ve finished recording your take.
Refrigerators are another appliance that produce noise. Make sure that the room that you record in doesn’t have one inside. The hum of some refrigerators are not particularly loud but it can still be heard by people who have sensitive ears so give them a break and don’t record near a refrigerator.
