To know the effect of Iranian immigrant’s sound and smell on European city, I tried to explore the identity of Tehran in sound and smell.Valiasr street runs from the Tehran's railway station in the south of the city to the Tajrish square in the north.The longest street in the city with had connectivity with religion, historic and cultural cores of old Tehran from south to north, connected many social classes with different socio-economic characters in conflict with each other.
