Question

Phase cancellation must be considered when using mic placement techniques, especially when combining multiple mics. Which of the following techniques is applied?

1) Phase cancellation
2) Mic placement
3) Combining multiple mics
4) None of the above

Answer 1

Phase cancellation must be considered when using mic placement techniques, especially when combining multiple mics. It occurs when sound waves from different microphones interfere with each other, leading to the loss or cancellation of certain frequencies. Understanding mic placement and different microphone polar patterns is crucial to avoid phase cancellation.

Step-by-step explanation:

Phase cancellation must be considered when using mic placement techniques, especially when combining multiple mics. This is because phase cancellation can occur when the sound waves from different microphones interfere with each other, resulting in a loss of certain frequencies or even complete cancellation of sound. It is important to understand mic placement and how different microphone polar patterns can affect phase cancellation. For example, if two microphones are placed close together and one is set to pick up sound from the front (cardioid pattern) while the other is set to pick up sound from all directions (omnidirectional pattern), the sound waves they capture may cancel each other out.
