Abstract:Mean scores for telephonic speech discrimination were over 85% for CID sentences and 28-59% for bisyllabic words. The Siemens M55 was superior to the other mobile telephones tested.
“…For those patients without a mobile telephone available, a Siemens M55 was employed, as this model has demonstrated excellent sound quality in previous studies [14]. A list of the mobile telephones employed is given in Table II.…”
Mean speech discrimination without the adapter in a quiet environment was 51.2%. In a noisy environment, mean discrimination increased significantly with the adapter from 30.3% to 42.9%. No statistically significant difference was found between speech discrimination in the quiet environment without the adapter and speech discrimination in the noisy environment with the adapter. When comparing speech discrimination in open field without lip-reading with equivalent telephonic conditions a statistically significant difference was found in favour of the open field.

“…Castro et al (19) measured live-voice speech recognition in quiet and in noise for 18 participants using MED-EL implants with four different telephones: a landline, two different mobile telephone models, and the users' own mobile phone. Live-voice speech recognition was evaluated with the Central Institute for the Deaf (CID) sentences (Spanish version) in quiet and with bisyllabic words in quiet and in noise.…”
A wireless HAT for the mobile telephone provides bimodal users with significant improvement in word recognition in quiet and in noise over the mobile telephone.
“…Alternatively, the signal transmission characteristics over landlines in Western Australia could be particularly poor as compared with those in Spain, where Castro et al completed their study. 10…”
Many cochlear implant recipients achieve good objective telephone speech perception performance, indicating that they should be effective telephone users, especially when using mobile telephones and among younger implant recipients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
