Recording a harbour that changed sound
Before the old harbour district was rebuilt, sound historian Amira Koss received six weeks to record it. The warehouses had already been emptied and demolition fencing cut off half the streets, so the commission appeared to concern disappearance: capture what remained before machinery replaced it. Amira rejected that premise almost immediately. A district does not possess one soundscape waiting to be collected. It is heard from particular positions, at particular hours, by people whose work determines what counts as signal and what as background.
37Her first recordings seemed to confirm the conventional story. Gulls, rigging and water dominated the early morning, while lorries and metal doors arrived later. Yet a retired crane driver listening in the archive room complained that the harbour sounded too open. The recordings lacked the low electrical hum that had once filled the loading sheds and, more importantly, the short shouted exchanges by which workers coordinated movements they could not see.
38The machines had gone, so those sounds could not simply be recovered. Amira asked former workers to mark on a plan where they had stood and what they listened for. Several described the same warning bell differently. One remembered its pitch; another remembered the interval before a suspended load began to move. Their accounts disagreed because they occupied different parts of the operation.
39To test the descriptions, the team built a temporary installation inside an empty warehouse. Small speakers reproduced fragments of bells, motors and voices at the locations indicated on the plan. The aim was not theatrical realism. Visitors walked the space while former workers adjusted volume and timing, revealing which sounds had carried information across distance and which had been masked by the building itself.
40One discovery concerned silence. In oral interviews, workers had described the harbour as continuously noisy. During the installation, however, they identified brief pauses before a crane changed direction or a gate opened. Those pauses had been operational: attention intensified because an expected sound was temporarily absent.
41The finding changed the public exhibition. Amira abandoned the continuous soundtrack originally requested by the museum and created several listening points separated by quiet. At one point, visitors heard only water and a distant road until a signal interrupted the scene; at another, the absence of a motor became noticeable only after its pattern had been learned.
42The redevelopment company initially worried that the exhibition would make the new district appear inauthentic. Its marketing promised continuity with maritime heritage, while Amira’s work showed that continuity could not be delivered by preserving a few characteristic noises. The operational relationships that had made those noises meaningful had disappeared with the work.
43When the exhibition opened, some former workers said it sounded unlike the harbour they remembered. Amira regarded this not as a failed reconstruction but as evidence of the project’s honesty. No single listener had occupied the whole district, and memory had rearranged repeated days into characteristic scenes. The archive now contained raw recordings, conflicting testimony, spatial experiments and the decisions behind the exhibition. It did not preserve the harbour’s sound. It preserved several ways of asking what had once been audible to whom. The team also compared recordings made by microphones mounted at head height with those fixed near machinery and under metal walkways. The same event changed character across a few metres: speech became intelligible where motors receded, while a signal clear to an operator disappeared into reverberation for a visitor. These differences prevented “the sound of the harbour” from becoming an average mix detached from the listening positions through which work had been coordinated. They also exposed a preservation dilemma, because combining channels into a balanced recording produced an acoustic overview no worker could ever have heard. Copyright introduced another layer of selection, because some commercial recordings of the harbour could be played publicly while workers’ private tapes required individual permission, making the legally available archive systematically cleaner and more official than the remembered workplace. Amira kept a register of material that existed but could not be reproduced, so absence in the exhibition would not be mistaken for absence in the historical record. She also invited contributors to describe why access was restricted, recognising that privacy, ownership and embarrassment produce different silences even when the result for a visitor is the same unheard sound.

For that reason, the commission was reframed as an investigation instead of a rescue. The team would record surviving sounds, but it would also document missing relations: blocked sightlines, working rhythms, inherited expectations and the unequal access of different listeners to the same event.
The revised design made the visitor responsible for assembling the sequence. There was no route that delivered a complete historical atmosphere, and labels identified whose account shaped each listening point. The quiet between stations was not empty circulation space but part of the argument about selective attention.
The installation nevertheless produced moments of strong recognition. A mechanic standing near the reconstructed gate signal instinctively moved aside before laughing at his response. Such reactions were valuable, but Amira refused to treat them as proof that the whole arrangement was historically correct.
That objection exposed a bias in the recording method. Amira’s microphones captured what travelled cleanly through open air, whereas workers had listened inside structures, beside machinery and through the expectations of routine. Technical clarity had produced a version that sounded plausible to outsiders and incomplete to participants.
The harbour authority had kept detailed maintenance logs, although these mostly described faults rather than ordinary operation. Amira used them to date several changes in machinery, but the documents could not indicate how a replacement motor altered conversation at the far end of a shed.
The final negotiation concerned the word “heritage”. Amira agreed that new residents might value a connection with the harbour, but argued that a familiar bell played decoratively in a café would preserve a sound while reversing its former function. Continuity required admitting transformation rather than disguising it.
The disagreement prevented the team from selecting one account as the accurate memory. Instead, each description became a hypothesis about a listening position and a task. The bell was not a self-contained object with a fixed meaning; its significance depended on what the listener was waiting to happen next.
These absences complicated the usual opposition between noise and quiet. Silence could be rest, exclusion or a highly informative interruption, depending on the sequence around it. Reconstructing only the loudest elements would therefore remove one of the ways experienced workers had detected change.
