Comparison of Speech Perception Outcomes Between Bluetooth Direct Streaming and Conventional Sound-Field Audiometry in Cochlear Implant Users
摘要
Abstract
Objective To investigate the clinical value of Bluetooth Direct Streaming(BDS)technology in hearing threshold and speech recognition testing for cochlear implant users,to compare speech recognition outcomes between BDS and conventional sound-field(SF)testing conditions,and to evaluate the feasibility of BDS as a supplementary approach to postoperative auditory assessment.This study aimed to provide evidence for remote programming,home-based follow-up,and rehabilitation monitoring in cochlear implant users.Methods Thirty-one Nurotron cochlear implant recipients were enrolled.A balanced crossover design was applied to control for potential order effects.Each participant completed speech recognition testing under both BDS and SF conditions.Subjective loudness matching was performed to make the output levels under the two conditions as comparable as possible.Chinese open-set speech perception materials were used to assess disyllabic word and sentence recognition in quiet.Paired t-tests were used to compare speech recognition scores between the two testing conditions.The improvement in recognition scores under BDS relative to SF was calculated,and the proportion of participants showing a BDS advantage at the individual level was also analyzed.Results Overall,speech recognition scores under BDS were significantly higher than those under SF(P<0.05).The disyllabic word recognition score was 69.6%±24.0%under BDS and 62.9%±25.1%under SF,with 20 participants(64.5%)showing a BDS advantage.The sentence recognition score was 65.7%±31.3%under BDS and 55.1%±27.6%under SF,with 26 participants(83.9%)showing a BDS advantage.The improvement in sentence recognition under BDS was 10.6%±16.1%,greater than the improvement in disyllabic word recognition(6.7%±15.2%);however,the difference between the two improvement magnitudes was not statistically significant(P=0.203).Conclusion The BDS technology can improve speech recognition performance in cochlear implant users in quiet,particularly in sentence recognition testing.This technique is easy to operate and may reduce the interference from environmental noise,reverberation,and sound-field equipment conditions on test results.Therefore,the BDS has the potential to serve as an effective supplement to conventional SF testing.The present study provides preliminary evidence supporting the application of BDS to postoperative assessment,remote programming,and patient self-testing for cochlear implant users,and may contribute to optimizing postoperative rehabilitation assessment and improving follow-up efficiency.关键词
