Selecting the right measurement microphone requires matching the transducer type, frequency range, dynamic range, and calibration class to your application. This guide covers the key parameters.

• Free-field vs pressure-field vs random-incidence microphones
• 1/2" vs 1/4" capsule sizes and their applications
• Class 1 vs Class 2 performance to IEC 61672
• Self-noise and dynamic range requirements for your SPL range
• Calibration requirements: QA/AC factory vs ISO/IEC 17025 accredited
• TEDS identification for automated multi-channel system setup
