What do Shure's guides say about microphone distance, proximity effect and plosives for voice recording?

Problem: get a clear, un-muddy voice at the mic. Conditions: single talker, directional (cardioid-type) mic. Method (Shure educational publications and the MV7 guide): keep the mic as close as practical to avoid picking up room reflections and reverberation, but not so close that proximity effect (a rise in low-frequency response with directional mics up close) makes the voice muddy or bassy; aim the mic from below or above rather than straight at the mouth to reduce p/t pops; add an external pop filter, which also helps maintain a consistent distance; keep the mic away from reflective surfaces. Distances quoted: about 6-12 inches from the mouth at roughly a 45-degree angle for a stand or handheld mic in the film/video guide (3-6 inches adds bass emphasis); 1-6 inches for the MV7 podcast mic (more bass, intimate sound, maximum off-axis rejection) or 6-18 inches in the MV7 Far setting. The inverse-square rule: doubling the source-to-mic distance cuts the sound pressure reaching the mic sharply, so halve the distance for a clear improvement. The MV7 guide offers a high-pass filter to reduce proximity effect and says to maintain the placement that works. Failure modes: moving in and out changes tone and level; omni lav mics have no proximity effect but pick up more room. Limitations: manufacturer guidance for their own mics; numbers differ by model. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Limitations: Distances are model-specific; sample figures are from three separate Shure documents. No Neumann or Sennheiser document was fetched. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
