This paper stresses the relatively high prevalence of auditory abnormality in multiple sclerosis. An auditory test battery consisting of the acoustic reflex (AR), the auditory brainstem response (ABR), the masking level difference (MLD) and speech audiometry (SA) was administered to 62 patients with diagnosed 'definite' multiple sclerosis. The AR showed the highest identification rate (71%). SA was next (55%), followed by the ABR (52%) and the MLD (45%). The combination of an abnormality on either AR, ABR or SA yielded a 90% identification rate. Interestingly, the combination of AR or SA or MLD yielded an 87% identification rate without any contribution from ABR.
