This month a White Paper by the British Society of Audiology appeared reaffirming their position alongside invited commentaries. So what is all the fuss about?

One of the most widely-used assessments is the SCAN-C battery which has four subtests: Filtered words: Repeat words that have been low-pass filtered, so they sound muffled Auditory figure-ground: Repeat words that are p...
