AB  - This paper describes an easily-run test that allows the short-term peak power and maximum SPL capabilities of amplifiers, electronic systems, loudspeakers, and sound reinforcement systems to be evaluated over the complete audio range. It is based on the use of a series of eleven octave-bandwidth tone-burst wave files at standard octave-center frequencies of 16 Hz to 16 kHz. The tone burst wave-shapes are very similar to those found in typical music program material. For a specific peak power or peak SPL frequency-response test, each tone burst is sequentially applied to the device under test and the maximum output is assessed at each frequency either subjectively or objectively. This differs from the author’s past work on the same topic that essentially accomplished the same test using a series of 31 third-octave bandwidth tone bursts. This new proposed test method uses far-fewer tone bursts and as a result the test is much easier and quicker to accomplish.
