In a non-shadowing dichotic loudness judgment task, 20 Ss matched speech and white noise intensities at 60, 70, 80, 90, 100, and 110 db. Above 70 db, Ss judged speech to be louder than white noise, at 70 db they were judged to be equally loud, but at 60 db white noise was considered to be louder than speech. These findings are discussed in terms of the attenuability of different types of material.
