New IEEE Standard – Superseded. Techniques for objective measurement of electroacoustic and voice switching characteristics of analog and digital handsfree telephones (HFTs) are provided. Due to the various characteristics of HFTs and the environments in which they operate, not all of the test procedures in this standard are applicable to all HFTs. Application of the test procedures to a typical HFTs should be determined on an individual basis.<\/p>\n
