QUESTION: How can I remove ventilation system noise from recordings?

ANSWER: Unfortunately, there is no magic solution once it’s already recorded… Noise attenuation needs to be considered at the time of recording. Ventilation system noise is mostly composed of specific frequencies. The trick is to use an audio equalizer to attenuate the frequencies derived from the ventilation system.

Step 1: Make sure the ventilation system is turned on in the interview room
Step 2: Put your headphones on
Step 3: Increase your recording system’s volume to the maximum
Step 4: Adjust the frequency bands starting with the lowest band until you achieve maximum attenuation of the ventilation system sounds

There is no standard solution. Simply adjust the different frequency bands until you achieve maximum noise attenuation in the interview room.
