There was agreement among the referees with respect to the words and figures. The SRPI test can be rapidly and easily applied, allowing evaluation and systematic monitoring of speech perception ability regardless of child verbalization capacity.
The efficacy of an internet based teleconsultation for hearing aid probe microphone measures in hearing impaired adults was evaluated. The amplitudes of face to face (F) and remote (R) real ear unaided response (REUR), real ear aided response (REAR) and real ear insertion gain (REIG) were compared. The measurement error for repeated measures of REUR, REAR and REIG was analyzed. Participated in this study: group A: 60 adults (mean age: 67 years), with unilateral (n=15) or bilateral (n=45) hearing loss, totalizing 105 ears; group B: 19 normal hearing adults (mean age: 28 years) totalizing 19 ears. Behind the ear hearing aids with no directional microphone, noise reduction and/or feedback cancellation were used. For group B these hearing aids were adjusted as to produce the least amount of gain and output. Five audiologists volunteers helped the data collection. The Unity PC Probe Mic (Siemens) coupled to a personal computer were used by the researcher to carry out face to face measures. For the remote measures this equipment was connected to a local area network (LAN-10 Mpbs). The volunteer and the participant were located in this room (test site). At the remote site the researcher used a notebook connected to the LAN. Webcams and headsets were used for audio and video capture which was transmitted in real time by the Polycom PVX software, which was also used for application sharing. By means of remote controlling of the PC Probe Mic equipment the researcher could perform the remote real ear measurements in the participants. Four repeated measures of REUR, REAR and REIG were obtained for group B only. Strong and significant correlations (Pearson) were obtained between face to face and remote real ear measures. Paired t tests revealed small but significant differences between face to face and remote REUR and REAR. Analysis of variance showed significant differences between repeated measures. Measurement errors for face to face and remote real ear measures were very similar. The differences as well as errors found between face to face and remote measures were never higher than the reported variability for probe microphone measures themselves. It is possible to carry out probe microphone measures by means of teleconsultation / telehealth. Further investigations to validate this procedure are necessary.
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.
