Abstract
The development of the audio subjective test method now known as MUSHRA took place in the EBU groups B/CASE and B/AIM leading eventually to an ITU-R Recommendation.

The name is derived from the way in which the signals to be evaluated are presented and the way in which hidden references and anchors are included.

The design philosophy was to provide a less sensitive, but still reliable (repeatable, reproducible), test method that was less costly to implement than BS.1116. The way in which these intentions were realised is described.
