Weaknesses 👎

  1. Not a design manual – It assumes you already understand acoustic filtering, FEA, or analog methods. Beginners find it overwhelming.
  2. PDF formatting issues – Many scanned copies (common online) have poor figure resolution, especially mode shape diagrams and P&IDs.
  3. Cost – Official API copy is ~$200–$300. Free PDFs floating around are often outdated (e.g., 1st edition vs. 2nd edition, 2019).
  4. Limited to PD machinery – Useless for centrifugal pumps or fans.
