Mix Your Own Soundscape

Is it possible to explore immigrant cultures through soundscapes? The Tenement Museum in NYC has a wonderful website focusing on the soundscapes of the Lower East Side. Many of the sounds available on their map are recordings of street life in that part of the city. What's interesting is that the web site allows you to mix the sounds from different places and create your own sound image of "immigration and the formation of identity in New York’s Lower East Side". Recordings of visitors' mixes are available here. I particularly like the one called 'Sounds kinda like home'. (Thanks to Shaylih for the link).
