Möjligheten för tillämpandet av taluppfattbarhetsindexet i den kliniska hörselvården (Swedish)
Abstract [en]

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.

Abstract [sv]

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.
