Design and analysis of subjective acoustical experiments which involve a quantal response
Subjective acoustical measurements involve quantities which do not possess an intrinsic scale of magnitude and so the only observations possible are in the form of very simple classification judgments or quantal responses. These measurements are usually also concerned with relating the subjective response to some objective, physically measurable stimulus. Much of the methodology developed in the broader field of biological experimentation is surprisingly appropriate to these problems. Some examples are given of the application of “probit analysis” and “analysis of variance” to the measurement of telephone circuits. These statistical methods used with appropriate designs of experiments not only yield valid confidence intervals but also point to the most efficient method of conducting the measurements through separation of the several sources of variation.
