The present investigation examined speech perception in noise of adults with and without multiple sclerosis (MS). Institute Electrical Electronic Engineers (IEEE) sentences were presented at a constant level 65 dBA L(eq) (equivalent continuous [4 dB exchange rate]) from loudspeaker located 0-degree horizontal azimuth 1.2 m the study participant. Uncorrelated multitalker babble was four loudspeakers positioned 45-, 135-, 225-, 315-degree azimuths 1.7 starting presentation for 55 L(eq). increased systematically 1 steps until subject obtained 0% key words correct on IEEE sentences. Results revealed significant difference between two groups nine signal-to-noise ratios. Some clinical implications these results are discussed.
