Verification tests are not open ended, or philosophical. We want specific answers to specific questions. We structure
Test procedure structure Subject : What do we want to know (e.g. polarity or maximum SPL)? Procedure : What tools and steps are required (FFT analyzer phase, SPL meter)? Units : How is it quantified (e.g. normal or inverted, 112 dB SPL)? Standards : What is expected and/or acceptable (e.g. normal, 110 dB SPL)? Result : What is the outcome (e.g. pass, pass)?
