SPL numbers can look impressive on a spec sheet – but what do they really tell you? As RP-1 brings standardized, engineering-grade clarity to loudspeaker data, it’s time to move beyond the marketing fluff and dive into what sound pressure level measurements actually mean, how they're taken, and how to compare them meaningfully.

In this 90-minute course, learners will explore peak, continuous, and time-weighted SPL measurement methods, understanding how each approach reflects real-world performance. You'll also unpack the critical factors that affect SPL outcomes – noise types, crest factor, and driver excursion (including Xmax)—and how these variables shape the limits of what a loudspeaker can do.

Cut through the confusion of SPL specs and learn to separate marketing from meaningful measurement. This course brings clarity to the numbers and confidence to your comparisons. By the end of this course, learners will be able to evaluate and compare loudspeaker SPL measurements using peak, continuous, and time-weighted methods, understanding the roles of noise types, crest factor, and driver excursion (including Xmax) in standardised measurement practices.
