Subtle Sound Design - Designing for Experience Blend in a Historic House Museum
Summary
Yates and Løvlie report a research-through-design study of a digital sound installation at Bakkehuset, a historic house museum in Copenhagen. The prototype used hidden speakers, period-inspired voices, music, and domestic sound effects to evoke the social atmosphere of Kamma and Knud Lyne Rahbek's early-1800s home without disrupting visitors' sense of authenticity. Visitor interviews before and after installation showed that most visitors valued the sound as atmospheric, life-giving, and supportive of imagining past life in the house. The authors argue that subtle, open-ended sonic augmentation can communicate immaterial cultural heritage in historic houses while avoiding intrusive or screen-based museum technology.
Important Keywords
- Historic house museum: a museum setting that preserves and presents a historically significant home.
- Museum experience design: designing visitors' interpretive and sensory experience of museum spaces.
- Digital sound installation: a technology-based sound layer added to the museum environment.
- Immaterial cultural heritage: intangible cultural qualities such as voices, routines, social life, and atmosphere.
- Hybrid museum experiences: experiences blending physical heritage spaces with digital media.
- Seamless design: integrating technology so it supports the setting without drawing attention away from it.
- Authenticity: the perceived fit between the sound design and the historical character of the place.
- Visitor imagination: visitors' active construction of scenes and meanings prompted by subtle sounds.
- Atmosphere: the mood or felt quality created by the combination of place, sound, and interpretation.
-
Bakkehuset: the historic house museum used as the paper's design case.
-
UX evaluation: evaluation of emotion, meaning, aesthetics, context, and usability.
- Field evaluation: evaluation in natural use settings.
- Anticipated UX: expected or imagined experience before actual use.
- Non-instrumental quality: experiential quality not reducible to task efficiency.
Important Concepts
- Experience blend: Digital augmentation should merge with the physical museum environment and visitors' motivations rather than pull attention away from the house.
- Subtle sound design: Invisible, non-screen-based sound can add a digital layer while preserving the visual and material character of a historic interior.
- Immaterial heritage: Bakkehuset's key heritage includes not only objects and rooms but also the former social atmosphere, conversations, music, and conviviality of the house.
- Authenticity as experience: The study distinguishes factually original objects from visitors' subjective experience of something as authentic or real.
- Open-ended atmosphere: Short, fragmented, non-literal sounds gave visitors hints rather than a full narrative, letting them use memory and imagination.
-
Social flow: Pauses, limited placement in one room, and non-demanding audio helped visitors remain in control of their visit and talk with companions.
-
Experience evaluation should consider lived experience, emotion, enjoyment, aesthetics, non-instrumental qualities, expectations, and context, not only task performance.
- Field evaluation studies real users in natural settings and is especially relevant for situated experiences such as museums.
- Anticipated UX concerns expected experiences, feelings, needs, and wishes before the full product exists.
- Prototype materials used in evaluation should help participants imagine the experience while keeping comparison variables consistent.
Examples
- The final installation used five short sound scenarios with silent breaks, replacing an earlier continuous 15-minute audio file that felt too demanding.
- Sounds included poetry reading, small talk, singing, piano playing, coughing, chair movement, glasses on a wooden table, and pages turning.
- Speakers and digital units were hidden in furniture, including a speaker inside the piano and one under the dining table.
- Copies of handwritten letters, books of poetry, fresh flowers, and fruit were placed on the table to align visual, sonic, and olfactory cues.
- Visitors described sensing life, human presence, and atmosphere; some initially thought the sounds came from real people in the room.
