A simple sound can evoke powerful images. Everyday noises and happenings can conjure different meanings for different people.
Based on this idea, the BBC is creating a Tsunami Audio Memorial.
Over the next six months, the BBC World Service, Radio 4 and Asian Network will gather sounds and stories for an historic audio tribute to the region and people affected by the tsunami. The material will be broadcast in special programmes at the end of the year.
The areas affected by the tsunami are rich in sound, from Indonesian fishermen bringing in their early morning catch or the cacophony of a traffic-filled street in Thailand.
What sounds capture India, Sri Lanka, Indonesia, Thailand or the Maldives for you and why? What are your "audio" memories of these areas affected by the tsunami? Do you live there? Have you travelled to the region? Do you have family there? Send us your memories.
You may have stories of sounds related to the tsunami, such as mobile phone messages, holiday videos, coastal sounds or the noise of reconstruction.
If you have a particular "sound story" of the tsunami-affected region, you can record a message on our dedicated phone line: +44-1223-589-200 (calls are charged at the standard UK rate, plus your local country charge).
Or you can email us at email@example.com and by using the form on the right hand side.
If you have audio recordings you can send them to us at:
Tsunami Audio Memorial
BBC World Service
We promise to return your recordings if you send them in.
The Tsunami Audio Memorial was inspired by the Sonic Memorial Project, an idea from the Kitchen Sisters on National Public Radio. After 9/11 they asked listeners to contribute sounds and stories about the World Trade Center. You can hear those stories at:
