DIN EN 60645-2:1997-04

The document describes equipment which is specifically designed for speech audiometric purposes. It specifies the requirements for an audiometer where speech is used as a test signal. However, to avoid duplication, if does not specify those elements that are common to both pure tone and speech audiometers. Performance requirements are given for both live voice and recorded speech inputs. Although live speech audiometry may not be capable of meeting the object of this document it is widely practised, particulary with children, and therefore a specification is included in order to ensure as high a degree of reliability as possible.
