PLACID Instruments publishes technical whitepapers on acoustic measurement topics that merit deeper treatment than a blog article or product page can provide. Whitepapers are written for measurement professionals who need to understand the underlying science and engineering trade-offs in microphone selection, calibration uncertainty analysis, and measurement system design — and who need to defend their instrument and methodology choices to colleagues, clients, or regulators.
The PLACID approach to whitepapers is straightforward: identify a question that measurement professionals consistently struggle with, answer it thoroughly and honestly using data and analysis rather than marketing language, and provide guidance that is genuinely useful regardless of which instruments the reader ultimately purchases. This approach reflects our belief that technically credible content builds more durable relationships than promotional content.
All whitepapers are available for free download without registration. We believe technical information should be accessible to the measurement community without barriers. New whitepapers are published several times per year — contact us to be notified of new publications.
Each PLACID whitepaper starts with a specific technical question that measurement professionals regularly ask — a question where available information is scattered, inconsistent, or too theoretical for practical decision-making. We compile measurement data, uncertainty analysis, and standards references into a structured answer that can be cited in internal technical reports and regulatory submissions.
Whitepapers are reviewed for technical accuracy before publication. Where we reference published standards, we cite the specific edition and clause. All uncertainty claims are calculated to GUM methodology. If you identify an error or have updated data that should be incorporated, contact us — we issue revised versions when warranted.
