investigating quick speech-in-noise comprehension in adult bimodal users

Introduction: the use of cochlear implants, due to technological limitations, causes problems in speech comprehension in the presence of noise. this study aimed to evaluate the speech-innoise (sin) comprehension with emphasis on high-frequency components between users of different bimodal adult. materials and methods: this study was conducted on 33 adult participants with a mean age of 36 years using bimodal (cochlear implant in one ear and hearing aid in another ear: ci/ha) style of different companies. quick sin with emphasis on high-frequency components was performed on the participants using an audiometer, an amplifier, and one speaker. results: comparing the average percentage of correct answers from the word recognition test in the presence of noise in bimodal users showed that the cochlear brand provides a better signal-to-noise (snr) compare to other brands. our result shows that bimodal users of advance bionic and med-el groups have better performance in speech recognition than other brands. conclusion: bimodal users of advance bionic and med-el have better snr loss than other brands. besides, further studies on different ages can be helpful to make the right decision in this regard.
