Hearing-impaired individuals that use hearing aids often experience problems when exposed to daily situations in life. The dierent environments include for example classrooms, oces and public areas. For the hearing impaired, the correct adjustments of the hearing aids are of great importance. For these settings to be proper, a measurement called the Speech Intelligibility Index (SII), is questioned to be implemented in the clinical hearing care. To answer this question of issue whether feasibility lay in the implementation of SII in the clinical hearing care with the interface of hearing aids, a literature study ordered by the Hearing- & Balance Clinic (H&B) at Karolinska University Hospital situated at Rosenlund Hospital, was initiated. The focus of the study was primarily held in concern of SII as a hearing aid validation measurement and later extended to SII as a room acoustic measurement disregarding the eect of hearing aids. The result of the study showed that the use of SII in the clinical hearing care is troubled and further that the implementation as a room acoustic measurement is probable but has to be additionally investigated. / Horselskadade personer som anvander horhjalpmedel upplever ofta problem nar de benner sig i vardagliga situationer i livet. De olika situationerna innefattar exempelvis vistelse i klassrum, pa kontor eller i oentliga miljoer. For den horselskadade ar diverse justeringar av horapparaturer av stor betydelse. Dessa installationer kraver skilda matmetoder som utnyttjas inom horselvarden. Dock nns det en hel del parametrar som inte tas med i berakningarna som utfors av metoderna. I dagslaget ifragasatts darfor om ett matt som kallas taluppfattbarhetsindex (SII) har mojlighet att gora intrade i den kliniska horselvarden. Med den kliniska horselvarden menas om hansyn till horapparatur tar vid matningarna. For att besvara fragan om det nns en genomforbarthet for SII initierades en litteraturstudie som bestallts av Horsel- & Balans Kliniken (H&B) vid Karolinska Universitetssjukhuset pa Rosenlund Sjukhus. Fokus for studien var framst att utvardera SII som ett valideringsmatt da hansyn till horapparatur togs och utvidgades senare till att betrakta SII som ett rumsakustiskts matt, dvs da eekten av horapparater fransags. Resultatet av studien visade att anvandningen av SII i den kliniska horselvarden ar problematisk och vidare att intradandet av SII som ett rumsakustisk matt ar troligt men maste undersokas ytterligare.
