Abstract
Afhandlingen beskriver analyse og design af et Nice Noise System (NNS), en lydløsning der skal gøre truck hørbare i det støjende produktionsmiljø hos Sauer‑Danfoss og dermed øge sikkerheden. Problemet belyses fra tre vinkler: medarbejderne, truck og omgivelserne. Der undersøges, hvilken type lyd der er passende, ved at definere principper med udgangspunkt i truckens adfærd. NNS er designet som et computerbaseret system, der lagrer lydene digitalt. En pitch-bending metode (ændring af tonehøjden) vælges, så lyden følger truckens hastighed og giver indtryk af et køretøj i bevægelse. En lyttetest er gennemført hos Sauer‑Danfoss med deltagelse af medarbejdere fra produktionen. Lydfiler og demoer er vedlagt på en cd-rom bagerst i rapporten.
This thesis presents the analysis and design of a Nice Noise System (NNS), a sound solution intended to make trucks audible in Sauer‑Danfoss’s noisy production environment and improve safety. The problem is examined from three perspectives: the workers, the trucks, and the environment. The study explores what sounds are appropriate by defining principles based on truck behavior. The NNS is designed as a computer-based system that stores the sounds digitally. A pitch-bending method (changing the pitch) is chosen so the sound follows the truck’s speed and conveys the impression of a real vehicle in motion. A listening test was conducted at Sauer‑Danfoss with participants from the production facility. Sound files and demos are included on a CD‑ROM at the back of the report.
