RTA/SPL Challenge

RTASPL flat

The IASCA RTA/SPL Challenge is a competition to show how well a sound system performs across all frequency ranges through the sound spectrum, as well as at higher output levels . RTA/SPL is an interactive format; in the RTA portion of evaluation, the competitor is rewarded for tuning their system to reproduce all frequency levels in the sound spectrum. The SPL section of the challenge is done with music only; no test tones, sweeps or bass bombs, the measurement is taken using full range sound.

Scores from the SPL level and the RTA curve of the system are then combined for an overall system performance score, determining the winner.
