The PLACID Instruments blog publishes technical articles, product insights, and application guidance for acoustic measurement professionals. Articles are written by practising engineers and are aimed at people who are already working in acoustic measurement and want to go deeper — not introductory-level content for general audiences.
Topics range from fundamental measurement methodology — how to correctly select a free-field vs pressure-field microphone, how to interpret a calibration certificate — to specific application guidance for environmental noise monitoring, industrial noise compliance, building acoustics, and NVH testing. We also cover data acquisition system selection, signal conditioning, and software tools for analysis.
New articles are published regularly. Subscribe to our newsletter to receive notification of new publications, or follow PLACID Instruments on LinkedIn. All articles are written with technical precision and without commercial bias — if a third-party standard, method, or instrument is the right answer for a question, we say so.
Each article is written to be technically complete and independently useful — not as a teaser for a product page. If you identify a factual error in any article, use the contact form and cite the article title. Corrections are made within 5 business days of verification. If you have a measurement question that would benefit from a dedicated article, submit it through the contact form — many of our articles originate from questions where readers could not find a clear, technically rigorous answer elsewhere.
