Cupping around the microphone can cause audio feedback for a couple of reasons:
- Narrowed Pickup Pattern: Cupping the mic can narrow the pickup pattern of your mic and make it more sensitive to sound in the direction that it’s not cupped. This means it picks up more sound from the surrounding environment, including from the speakers, which increases the likelihood of feedback.
- Proximity Effect: When you cup the microphone, you often speak closer to it. This can boost the proximity effect (lower frequencies), making the mic more sensitive and more prone to feedback.
- Resonance: The enclosed space created by cupping can cause certain frequencies to resonate, which can be picked up by the microphone and amplified, leading to feedback. The small, enclosed area can also cause distortion, adding to the problem.
