Re: More to a measurement then the transfer function?
Putting on the scientist hat that basically specializes in interpreting measurements, I would say any measurement is only as good as the question the measurement was designed to answer.
Many people with a basic technical background are familiar with the idea of accuracy and precision of a measurement. The next step in statistics is the validity and reliability of the measurement.
What many people are not as familiar with ( and I sometimes struggle with this concept even with my college students) is that you can and should apply the same thought process to the entire experimental design.
In this case, validity comes down to: can the measurement process provide a definitive answer to the research question (hypothesis) being tested.
Applying that to this thread, designing a speaker, tuning a speaker, tuning a system, tuning a system in a particular space, checking the performance of a system, or running a show, all lead me to pose different questions, therefore; the transfer function gets set up and used in different ways.
