This paper describes a proposed test method that allows both the continuous and short-term maximum peak output and SPL for electronic and electroacoustic systems to be measured. Systems such as power amplifiers, loudspeakers, and sound reinforcement/cinema systems can be measured and specified over the complete audible range. The test is divided into two parts that individually assesses: (1) the system’s broadband continuous maximum output using various steady-state low-crest-factor test signals and (2) the system’s short-term narrow-band maximum output using high-crest-factor test signals. The combination of both tests completely specifies the system’s maximum output on a continuous and short-term narrow-band basis. A future Part 2 paper will go into detail concerning the tests and will illustrate with measured test results.
