Sound as Sculpture: Designing Public Art Audiences Can Touch and Hear

Sound as sculpture means treating audio as a physical material with placement, weight and reach, and building the audience's body into the composition. Tarek Atoui's Turbine Hall commission at Tate Modern shows how: the Guardian's review describes rough-hewn rocks and water basins visitors can sit on or climb, beneath brass trumpets and glowing drums suspended from the roof girders, all resonating with an ever-changing art of noises. Artists work this way by choosing objects for their acoustic behaviour, placing them to direct sound through a space, and inviting people to listen from inside the work. For students this is practical: prototype multi-sensory pieces, test them in freely entered public spaces.

What Atoui's Turbine Hall installation actually does

Writing in October 2026, the Guardian's reviewer describes the Lebanese artist's occupation of Tate Modern's Turbine Hall as an ingenious, interconnected sonic beast with funny, sad and mystical results. On the floor sit wide water basins and huge, flattish, rough-hewn rocks of the kind you might see on moorland or in a desert; visitors can sit, stand or climb on them. Overhead, immense elongated brass trumpets and giant glowing drums hang from the girders of the former power station's roof — the review's phrase is raining musical instruments. A translucent cone rises out of the ground like an ethereal minaret, and these sculptural creations and found objects resonate and echo with an ever-changing, invisible art of noises.

The review also captures the sound itself: an earth-shaking bass note throbs from a hanging trumpet — or perhaps from that translucent cone — then a drumbeat booms through the space, and a woman's plangent voice sings notes the writer calls achingly lovely. Notice what makes this sound as sculpture rather than sound as soundtrack. The objects are sized, shaped and placed to produce and direct audio, and the audience's body is invited into the composition, since sitting on a rock changes how you hear the room. One caution: this is a review excerpt, not full documentation, so details such as the exhibition's run, the complete instrument list or whether visitors may touch the water are beyond what we can verify here.

Treating sound as a sculptural material

Start with a shift in how you study materials. Every object has acoustic behaviour: a metal sheet rings, stone clicks and dampens, stretched fabric thuds, and a tube's note is set by its own resonance — length and geometry decide the pitch, while your breath is just airflow that excites it. Placement is a compositional act, because a sounding object aimed at a wall behaves differently from one aimed at open air, and height changes which frequencies reach a standing listener. Scale matters too: the review's hanging trumpets and ground-level cone suggest a deliberate spread of sources from above and below. Before sketching forms, our exercises begin with listening, because you cannot compose with a material you have never heard.

Our first exercise is a resonance inventory. Gather scrap materials — metal sheet, cardboard tube, stone, a basin of water, stretched fabric — and strike, tap, bow and blow through each, recording every result on your phone. Sort the recordings into low drones, mid tones and bright clicks, then choose two contrasting sounds and place their objects at opposite ends of a room. Walk the space slowly and mark where each sound is loud, muffled or doubled by reflection. This map is your first sculptural drawing: it tells you where a listener's body will sit inside the composition, and which placements invite people closer.

Prototyping multi-sensory work in the studio

Design for touch and hearing together from the first mock-up. Ask what a visitor can do with their body: sit, lean, climb over, rest a hand on a vibrating surface. Remember that bodies alter acoustics — a person sitting on a resonant platform damps it, and a crowd absorbs high frequencies — so build prototypes sturdy enough to be leaned on and safe enough to be climbed. Our exercise here is a listening seat: take a plain sturdy bench, attach one sounding element beneath or beside it, and test how vibration through the seat changes what a seated person hears compared with a standing one.

Our second exercise is eyes-closed testing. Invite three classmates to experience your prototype once with eyes closed and once with eyes open, and watch where they move, what they reach for and what they mishear. Closed eyes strip away the visual story and reveal whether the sound alone can hold attention and guide movement. Note every moment of hesitation or surprise, then change one variable at a time — height, material, distance — and repeat. Keep written notes alongside photographs, because a still image plus a clear description is often all a distant viewer, teacher or assessor will ever have of a work built around hearing.

Testing in free, non-gallery spaces

Galleries are the hardest places to test participatory work, because visitors there already expect to be careful. Freely entered spaces — a campus foyer, a library lobby, a covered market, a community hall — give you audiences who arrive without art context and must be won over by the work itself. Our exercise is a forty-eight-hour placement test: get permission, install a simple touchable sound piece, and observe in two-hour shifts. Count how many people stop, touch, sit or move away, and note the rules you had to negotiate: noise limits, safety, weather, cleaning schedules. Those constraints are real design briefs, not obstacles.

Document everything, because process evidence is what student opportunities actually see. If you submit work to a programme such as the Dynamic Art Award, entry is free, rolling assessment runs through the live period with no shared closing date, and valid AI feedback is private, with an optional provisional monthly leaderboard rather than formal awards. AI assistance must be disclosed, and original creative contribution is required. Be aware that current automatic assessment uses static image evidence and does not assess audio or interactive behaviour, so check the live programme and supported formats before submitting time-based work, and let strong photographs and descriptions carry what a microphone cannot.
