Technical Knowledge Base
Microphone Sound Field Characteristics
Free-field microphones are designed for capturing sound primarily emanating from a specific direction. The frequency response curve is meticulously engineered to counterbalance the pressure variations at the diaphragm, stemming from interference and diffraction effects.
Pressure-field microphones directly gauge the actual sound pressure level at the diaphragm. These find utility in measuring sound pressure levels on surfaces or within enclosed spaces where the microphone is part of the cavity wall.
Random-response microphones have a flat frequency response in diffuse sound fields where sound arrives from all angles.
Z-TECH offers a comprehensive selection of microphone variants for testing sound pressure levels (SPL) across an extensive array of applications.
