8.2.1 THROW DISTANCE AND SOUND LEVELS
The chart below helps answer the question, “how far can it throw?” The chart shows the maximum distance at which a given
model can reach 96 dB SPL on the A Scale (speech range). Consider a high-school football stadium where the crowd noise
is 86 dBA. At the recommended distance, an R.25 or R.5 would provide 10 dB headroom above the crowd noise. Even if
the crowd noise reaches 90 dBA, the R.25 or R.5 would still provide 6 dB of headroom which is acceptable for voice paging
and announcement systems (use a limiter to avoid clipping). In larger facilities, crowd noise can exceed 100 dBA. At motor
racing events, racing noise can exceed 120 dBA near the track. It is impractical and unsafe to try to page above these
levels. It’s better to train announcers to wait until the crowd (or motor noise) quiets down and to repeat the page.
