Summary of Issue: Clarification of note / awkward phrasing
Comment (Including rationale for any proposed change):
\"one quarter as loud\" sounds stilted. also, the note may benefit from being prefaced by something like \"In simple terms,\" or \"As a rough measure,\" or \"As a rule of thumb,\"...

Proposed Change:
Preface note with \"In simple terms,\" or \"As a rough measure,\" or \"As a rule of thumb,\" followed by \"sound that meets this requirement will be approximately four times quieter than the foreground speech content.\"
