Speech test with monosyllabic words in quiet and with competing sound
Abstract
This standard specifies requirements and characteristics for a German speech test with monosyllabic words in quiet and with additional sound in a free sound field. In quiet, both monaural and binaural measurements are taken into account, and with additional sound, only binaural measurements are taken into account. Measurements via headphones can also be carried out with appropriate free-field equalisation of the respective headphones. In addition, the standard contains the definition of important terms, definitions for the specification and determination of speech and additional sound levels, the provision of reference curves and instructions for conducting the speech test.
