The measurement microphone is one of the most critical components of any loudspeaker/room calibration system.
Trinnov’s sophisticated algorithms rely not only on extremely accurate acoustic measurements but also on the ability to localize the speakers’ positions and to detect early reflections. Our 3D microphone uses four mic elements in a precise tetrahedral arrangement. Each capsule is individually calibrated at the factory (±0.1 dB from 20 Hz to 24 kHz)
The resulting microphone calibration file is included in the microphone’s box on a USB stick. This file is installed in the Trinnov product being employed and all subsequent measurements are filtered through the calibration coefficients to ensure accuracy.
