[Voice acoustic analysis in patients with a hearing aid or cochlear implant].

The subject of our study was two groups of patients with hearing disorders: 23 cases implanted with multi-channel cochlear device (Nucleus Mini System 22) and 10 patients with perceptive hypoacusis who used hearing aids. The voice acoustic analysis was performed before cochlear implantation or application of a hearing aid and after a 6-month rehabilitation period. The acoustic analysis was carried out by means of a laryngophone connected to KAY 4300 instrument. The estimation of acoustic parameters of a laryngeal tone during rehabilitation process as well as parameters of spectrographic analysis was presented with the use of MDVP and CSL. Voice acoustic analysis can be an objective evaluation of progress in voice and speech rehabilitation process of patients with hearing disorders, particularly small children.
