MUIC & ACOUTIC – LIVE OUND & PA YTEM CALCULATOR
Monitor Wedge Feedback
A precise tool.
What is the Monitor Wedge Feedback & How does it work?
Monitor wedge feedback is a common issue in live sound setups, particularly when the sound from the monitor speakers reflects back onto the microphone, creating an unwanted loop. This can lead to howling or screeching noises that disrupt performances.
The frequency at which feedback occurs depends on the room gain and the placement of the speakers and microphones. Understanding these factors helps in minimizing feedback by adjusting speaker positions, microphone distances, and using appropriate acoustic treatments.
f = frac{v}{2L}
f = Feedback frequency (Hz), v = Speed of sound (m/s), L = Distance between speaker and microphone (m)

Frequently Asked Questions
What causes monitor wedge feedback?
Monitor wedge feedback occurs when sound from speakers reflects back onto microphones, creating an unwanted loop.
How does room gain affect feedback?
Higher room gain increases the likelihood of feedback as it amplifies reflected sound.
What is the best way to prevent monitor wedge feedback?
Adjust speaker positions, increase microphone distances, and use appropriate acoustic treatments.
Can adjusting speaker angles help with feedback?
Yes, angling speakers away from microphones can reduce direct sound reflection and minimize feedback.
What is the role of microphone proximity in feedback?
Closer microphones to speakers increase the chance of feedback due to higher gain levels.
How does using a monitor wedge differ from other speaker setups?
Monitor wedges are angled towards the stage, focusing sound on performers and reducing ambient noise pickup.
Is there software that can help calculate optimal speaker placement for live sound?
Yes, some audio engineering software includes tools to simulate and optimize speaker placements for minimal feedback.
