Musiklyssning genom hörapparater. Sally Allkins & Magnus Ericsson 2007

Sammanfattning

Syftet med denna studie var att undersöka hur musikintresserade hörapparatanvändare uppfattar musik genom hörapparater. Den teoretiska bakgrunden i uppsatsen har varit omfattande på grund av att ämnet är så mångfacetterat och komplext då både musik och hörapparater innehåller så många olika komponenter och egenskaper som i slutändan måste samspela för att uppnå ett så bra resultat som möjligt. Det mest centrala i studien har varit ett lyssningstest där musikintresserade hörapparatanvändare har skattat ljudkvalitet i två

hörapparater när olika musikstycken presenterades. Undersökningsgruppen bestod av tio personer mellan 42 och 74 år, varav två kvinnor och åtta män. Hörapparaterna som studerades i arbetet var Oticon Syncro, där hörapparatens grundprogram jämfördes med

musikprogrammet och Siemens Centra S, där två musikprogram jämfördes med skillnader i kompressionskarakteristik.

Studien visade tendenser till högre skattningar för grundprogrammet jämfört med musikprogrammet i hörapparaten Oticon Syncro, samt för musikprogrammet med snabb kompression jämfört med musikprogrammet med långsam kompression i hörapparaten Siemens Centra S. Det visade sig även att försökspersonernas preferenser i viss mån var en följd av vilken musikkaraktär som presenterades. Efter att ha genomfört denna studie

rekommenderar vi att i klinisk verksamhet använda två olika musikprogram med möjlighet att ändra kompressorns tidskonstanter. Denna rekommendation föreslås för hörapparatanvändare där musik spelar en viktig roll i deras liv.

Listening to music through hearing aids.

Abstract

The object of this study was to investigate how hearing aid wearers with an interest in music perceived sound quality when listening to music through their hearing aids. The theoretical background in the essay is extensive because the subject matter is complex: both music and hearing aids have many different characteristics and parameters that must work together in order to produce the best possible results. The emphasis of the study was centred on the music listening test, where hearing aid users with an interest in music have evaluated the sound quality in two different hearing aids whilst listening to several different pieces of music. The subjects were ten people from 42 to 74 years of age, two women and eight men. The hearing aids that were studied in the essay were Oticon Syncro, where the hearing aid’s speech programme was compared to its music programme, and Siemens Centra S, where two music programmes with different compression settings were compared with each other.

The study showed that there was a tendency for the speech programme to be preferred to the music programme in Oticon Syncro and that there was a tendency for the music programme with fast compression to be preferred to the music programme with slow compression in Siemens Centra S. The hearing aid users’ preferences depended to a certain degree on the type of music that was played. The results of this study indicate that it would be appropriate to programme two music settings in a hearing aid with the option to choose between different compression characteristics. This recommendation is only suitable for hearing aid users where
