Abstract [sv]

Denna undersökning har gjorts för att ta reda på vikten i att äga ett dyrt högtalarsystem när man lyssnar på strömmad musik samt hur påverkad man blir av vetskapen om priset hos vederbörande högtalare. Tre olika högtalare i tre olika prisklasser har testats. 22 personer deltog och fick lyssna på valfri låt igenom strömmningstjänsten Spotify. Lyssnarna fick först ranka högtalarna efter uppskattad generell ljudkvalité utan att se vilka högtalare de lyssnade på, sedan fick de göra om samma test fast med möjlighet att se högtalarna och vetskapen om hur mycket de kostade. Det visade sig att vetskapen om pris eller utseende inte hade någon påverkan på lyssnaren. Inte heller källan som musiken spelades upp ifrån, Spotify eller CD visade sig ha någon betydelse. Det har också visat sig ligga ganska lite koppling mellan pris och kvalité då den billigaste högtalaren rankades bland de bästa i detta test. Detta har lett till en diskussion om betydelsen av högtalarnas karaktär. Den karaktär som i sig kan ge lyssnaren en bra eller dålig upplevelse i den uppfattade ljudkvalitén beroende på lyssnarens egna preferenser. Frekvenskaraktären kan dominera över högtalarens många andra egenskaper. En billigare högtalare kan alltså föredras över en dyrare om frekvenskaraktären för den mindre påkostade högtalaren överensstämmer med åhörarens tycke och smak.

Abstract [en]

This study has been done to find out the importance of owning an expensive speaker system when listening to streamed music, and how influenced we are by knowing the price of the represented speaker. Three different speakers in three different price ranges have been tested. 22 people attended and had the opportunity to listen to any song through the streaming service Spotify. Listeners were first asked to estimate the overall sound quality of the speakers without being able to see them. The following test was equally executed but with the opportunity to see the loudspeakers and information on the retail price. It turned out that knowing the price or appearance had no impact on the listener. Neither the source of the music that was played, Spotify or CD turned out to be relevant. It has also shown that there was a poor connection between price and quality since the cheapest speaker was ranked among the best in this test. This has led to a discussion of the importance of the loudspeaker’s character. The character which could give the listener a good or bad experience of the perceived sound quality depending on the listeners own preferences. The frequency character can dominate the speakers many other qualities. A less expensive speaker can be preferred over a more expensive if the frequency characteristics of the more expensive speaker matches the listeners opinion.
