The methods may also be applicable to a wide variety of other communications equipment, including cordless, wireless, and mobile communications devices. Measurement results may be used to evaluate these devices on a standardized basis. Application is in the frequency range from 100 Hz to 8500 Hz. Keywords: analog telephones, digital telephones, electroacoustic measurements on telephones, handsets, headsets, IEEE 269, IEEE 269a, telephony, voice transmission performance. 517 $aIEEE Std 269a-2012 (Amendment to IEEE Std 269-2010): IEEE Standard Methods for Measuring Transmission Performance of Analog and Digital Telephone Sets, Handsets, and Headsets--Amendment 1 517 $aIEEE Std 269a-2012 606 $aTelephone$xEquipment and supplies 606 $aTelephone$xEcho suppressors 615 0$aTelephone$xEquipment and supplies. 615 0$aTelephone$xEcho suppressors. 676 $a621.386 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a9910135485203321 996 $aIEEE Std 269a-2012 (Amendment to IEEE Std 269-2010)$92578745 997 $aUNINA LEADER 03646nas 2201177- 450 001 9910133690503321 005 20230522010532.0 035 $a(DE-599)ZDB2677620-0 035 $a(OCoLC)857678623 035 $a(CKB)3330000000000200 035 $a(CONSER)--2015247800 035 $a(EXLCZ)993330000000000200 100 $a20130905a20119999 --- - 101 0 $aeng 135 $aur||||||||||| 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 00$aAudiology and neurotology extra 210 1$aBasel :$cKarger AG,$d[2011]- 215 $a1 online resource 300 $aRefereed/Peer-reviewed 311 $a1664-5537 517 3 $aAudiology & neurotology extra 606 $aAudiology$vPeriodicals 606 $aVestibular apparatus$vPeriodicals 606 $aAuditory pathways$vPeriodicals 606 $aAudiology 606 $aHearing disorders 606 $aPsychoacoustics 606 $aPsychophysiology 606 $aSignal detection (Psychology) 606 $aAudiology 606 $aHearing 606 $aHearing Disorders 606 $aPsychoacoustics 606 $aPsychophysiology 606 $aSignal Detection, Psychological 606 $aAudiologie$vPériodiques 606 $aVestibule du labyrinthe osseux$vPériodiques 606 $aVoies auditives$vPériodiques 606 $aAudiologie 606 $aTroubles de l'audition 606 $aPsychoacoustique 606 $aPsychophysiologie 606 $aDétection du signal (Psychologie) 606 $aSignal detection (Psychology)$2fast$3(OCoLC)fst01118271 606 $aPsychophysiology$2fast$3(OCoLC)fst01081674 606 $aPsychoacoustics$2fast$3(OCoLC)fst01081233 606 $aHearing disorders$2fast$3(OCoLC)fst00953415 606 $aAudiology$2fast$3(OCoLC)fst00821108 606 $aAuditory pathways$2fast$3(OCoLC)fst00821274 606 $aVestibular apparatus$2fast$3(OCoLC)fst01165685 606 $aAudiologia$2thub 606 $aOtorrinolaringologia$2thub 606 $aRevistes electròniques$2thub 608 $aPeriodical. 608 $aFulltext. 608 $aInternet Resources. 608 $aPeriodicals. 608 $aperiodicals.$2aat 608 $aPeriodicals$2fast 608 $aPeriodicals.$2lcgft 608 $aPériodiques.$2rvmgf 608 $aRevistes electròniques.$2thub 615 0$aAudiology 615 0$aVestibular apparatus 615 0$aAuditory pathways 615 0$aAudiology. 615 0$aHearing disorders. 615 0$aPsychoacoustics. 615 0$aPsychophysiology. 615 0$aSignal detection (Psychology) 615 2$aAudiology. 615 2$aHearing. 615 2$aHearing Disorders 615 2$aPsychoacoustics 615 2$aPsychophysiology 615 2$aSignal Detection, Psychological. 615 6$aAudiologie 615 6$aVestibule du labyrinthe osseux 615 6$aVoies auditives 615 6$aAudiologie. 615 6$aTroubles de l'audition. 615 6$aPsychoacoustique. 615 6$aPsychophysiologie. 615 6$aDétection du signal (Psychologie) 615 7$aSignal detection (Psychology) 615 7$aPsychophysiology. 615 7$aPsychoacoustics. 615 7$aHearing disorders. 615 7$aAudiology. 615 7$aAuditory pathways. 615 7$aVestibular apparatus. 615 7$aAudiologia. 615 7$aOtorrinolaringologia. 615 7$aRevistes electròniques. 906 $aJOURNAL 912 $a9910133690503321 996 $aAudiology and neurotology extra$92013340 997 $aUNINA
