Bakgrund: Monaurala lågredundanta taltester används, tillsammans med andra tester i testbatterier, för att undersöka centrala auditiva funktioner. Testgrupper som ingår i monaurala lågredundanta taltester är: lågpassfiltrerade taltester, tal-i-brus tester och tidskomprimerade taltester. Syfte: Syftet var att ta reda på vilka monaurala lågredundanta taltester som finns och vilka resultat man kan få på dessa. Metod: Litteraturstudie där experimentella studier har använts. Resultat: De monaurala lågredundanta taltester som har använts i de studerade artiklarna är filtrerat tal, meningar-i-brus, ord-i-brus, taluppfattning-i-brus, tal-i-brus, SPIN, R-SPIN, SSI/MCI, SSI/ICM, SIN, tidskomprimerade ord med olika kompressionsgrader, hackat tal, The Compressed Sentence Test och SCAN-A, SCAN-C med undertesterna Auditory Figure Ground och filtrerade ord. Försökspersoner med hörselnedsättning får signifikant sämre resultat än normalhörande på många av testerna. Barn får sämre resultat på flera av testerna jämfört med vuxna. Slutsatser: Det finns många olika monaurala lågredundanta taltester. De valda artiklarna tar upp fler monaurala lågredundanta taltester än vad som nämns i använd referenslitteratur.

Excerpt: As expressed in published guidelines, there are several components to the overall hearing aid fitting process. The primary focus usually surrounds the selection of the hearing aids and their special features, verification of the fitting, and then some type of real-world validation. Another component recommended in all published hearing aid fitting guidelines but often overlooked, is pre-testing.

Excerpt: What? You say you don't believe in prescriptive methods for programming hearing aids? Really? Then let me ask you this: Your Monday morning patient has a relatively flat 60 dB loss of cochlear origin. Would you program his hearing aids with 60 dB gain? Of course not. How about 10 dB gain? Not good either, right? Guess what—the moment you reached these conclusions, you're already using a prescriptive fitting approach.

A computer-based audiometric evaluation system has been developed. The system makes use of an IBM PC/XT/AT compatible personal computer to perform pure tone and speech tests and · comprises a plug-in card and custom software. The card contains pure tone and masking noise generators, together with amplifiers for a. set of headphones .and bone conduction transducer, patient and audiologist microphone amplifiers and a hand-held infra-red remote-control unit. A voice-operated gain-adjusting device on the audiologist's microphone eliminates the need for a sound pressure level meter during speech tests. The software-based user-interface makes use.of overlaid pop-up menus, context sensitive assistance.and a text editor on a graphics screen. Pure tone and speech data are acquired and displayed on a dynamic audiogram and speech discrimination gram respectively. This data may be stored and later retrieved from a patient data base. Further audiometric tests may be incorporated at a later stage.
