Measurement Microphones Explained: Choosing Accuracy Without Overspending
By PLACID Instruments Editorial – Published August 21, 2025
For engineers, consultants, and researchers working in acoustics or noise control, few tools are as fundamental as the measurement microphone. Yet, many buyers face the same dilemma: specifications across brands often look identical, but prices can differ dramatically. So, what really matters? And do you need to pay premium prices for reliable data?
What Makes a Measurement Microphone Different?
Unlike studio microphones, measurement microphones are engineered for accuracy, traceability, and compliance. Key features include:
- Omnidirectional pickup patterns
- Linear frequency response across the intended range
- Traceable calibration to IEC 61094 standards
Calibration and Standards
A microphone is only as reliable as its calibration. That’s why PLACID offers ISO 17025 accredited calibration certificates with every microphone upon request, ensuring full traceability and acceptance in compliance testing and legal contexts.
Types and Sizes
Choosing the right size and type is crucial:
- 1/4" microphones: Handle very high SPL (up to 180 dB), ideal for ship horns, explosions, or industrial machinery.
- 1/2" microphones: The most common, suitable for environmental and building acoustics.
- 1" microphones: Higher sensitivity, excellent for low-frequency and laboratory research.
Cost vs. Value
Top brands such as Brüel & Kjær, GRAS, and PCB Piezotronics deliver excellent performance—but at a significant premium. PLACID delivers the same compliance with IEC 61094 and ISO 17025, while costing 30–50% less.
