Abstract

When sound field speech audiometry is evaluated with competing noise, monosyllable and word intelligibility significantly vary according to the speech sound materials or the competing noise presentation method, even in the same subjects. Various competing noise methods in addition to the conditions described in ISO 8253-3 have been evaluated. In this study, monosyllable and word intelligibility were evaluated under three different types of competing noise conditions in a sound field, in 20 normal hearing subjects. As a result, in tests using speech material with less variable sound pressure levels of the word list, neither monosyllable not word intelligibility differed significantly between noise presentation from a loudspeaker placed in front of the subject and the competing noise conditions described in ISO 8353-3.
