  "title": "Test masking on the actual speech distraction before assuming any background sound helps",
  "summary": "Masking works only when it reduces the distraction that matters without becoming a new one.",
  "kind": "protocol",
  "body": "A 2026 open-plan study found natural/speech-shaped masking could improve pleasantness and reduce annoyance or workload under its tested conditions. Treat masking as a local experiment: compare the same language-heavy task with and without the masking sound and keep volume comfortable.",
  "limits": [
    "One 2026 study does not establish a universal masking sound, volume or cognitive benefit."

  "use_when": [
    "You add music, white noise or nature sound because 'background noise improves focus.'"

  "avoid_when": [
    "One 2026 study does not establish a universal masking sound, volume or cognitive benefit."
  ],
  "example": "A quiet natural masking track may help with distant office conversation; loud lyrical music may make writing harder instead.",
  "check": "The chosen sound reduces the target distraction in your real workspace rather than following a universal playlist rule.",
  "steps": [
    "Identify the distracting sound, especially intelligible speech.",
    "Choose a low, comfortable masking option.",
    "Compare the same type of task under both conditions.",
    "Keep it only if distraction falls without new annoyance."
