To demonstrate the repeatability, we measured a speaker 50 times in two of our TTC chambers and combined the data on a single graph.

Loudspeaker measurements with TTC chambers

The left-hand axis scales the level of the 100 measurements and the right-hand axis displays the uncertainty to a statistical confidence level of 95%; proving the repeatability is better than +/-0.25dB between the measured values. Guaranteeing repeatability, accuracy and correlation across Lab’s, across Production lines and across the World
