Abstract

Dette speciale undersøger, hvordan baggrundsstøj påvirker musikopfattelsen, med målet at bevare et naturligt lydbillede og mindske gener. Med fokus på støj i tog foreslås to metoder til at optimere musikafspilning i støjende miljøer. Den første metode sigter mod at gøre musikken hørbar på tværs af hele frekvensområdet. Den anden metode rummer samme funktion og tilføjer en subtil equalisering – små justeringer af bas, mellemtone og diskant – for at undgå en oplevet ændring i den tonale balance. Begge metoder blev vurderet i en parvis sammenligningstest, hvor deltagere lyttede til musik behandlet med de to metoder. Resultaterne var noget uklare, men en rangordning fremkom: Metode to blev overordnet foretrukket for mere naturlig lyd og mindre gene.

This thesis investigates how background noise affects the perception of music, aiming to keep the sound natural and reduce annoyance. Focusing on noise inside trains, it proposes two ways to improve music playback in noisy environments. The first method seeks to make the music audible across the full frequency range. The second includes that same functionality and adds subtle equalization—small adjustments to bass, mid, and treble—to avoid a perceived change in tonal balance. Both methods were evaluated using a paired-comparison listening test with music processed by each approach. The results were somewhat inconclusive, but a ranking emerged: the second method was generally preferred for its more natural sound and lower annoyance.
