It may just be a variant on the winter sounds we have now, but we need a sound background for the 12K BC level. Occasional distant animal sounds might make sense too. ChatGPT had some good suggestions:
For a 12000 BC Pleistocene Manhattan soundscape, consider including the following elements:
Wind: Strong, cold winds sweeping across the landscape, as it would have been an open tundra with sparse vegetation.
Water: The distant sound of glacial meltwater streams or rivers, possibly from the Hudson River or smaller streams forming from the melting Laurentide Ice Sheet.
Birds: Calls of early migratory birds, such as waterfowl or shorebirds, which could have been common in the area.
Ice: Occasional creaks or groans of ice as the glacier slowly retreats and melts, possibly including distant cracking sounds of ice calving off.
Animal Sounds: Distant roars or calls from megafauna like mammoths, mastodons, or saber-toothed cats, which might have roamed the area. Additionally, sounds of grazing herbivores such as ground sloths or prehistoric horses.
Insects: Buzzing of insects during warmer periods, though these would be relatively sparse.
Ambient Natural Sounds: General ambient sounds of an open wilderness, including rustling vegetation, particularly grasses or low shrubs.
