Simon Whetham is a British sound artist, born in 1970 and based in the United Kingdom. He works with sound recordings as material for composition, often using environmental recordings captured through a range of methods to isolate discrete or obscured sonic details. By removing sounds from their original context and often amplifying them, he creates work that treats familiar material in more abstract and unfamiliar ways.

His practice also includes performance and installation, where the space and the objects in it are treated as instruments. He publishes work through specialist outlets including Touch Music, Cronica, Dragon's Eye, Monochrome Vision and Entr'acte. He performs internationally and works across collaborations with musicians, performance artists, painters, video artists, dancers and poets.

Whetham also runs listening and field recording workshops in the UK, Estonia, Colombia, Chile and Australia. He receives commissions and awards for projects and installations, including his project Active Crossover, which is supported by Arts Council England and the PRS for Music Foundation. The project includes sound installation, performance, collaboration and workshops, and tours in the UK as well as being hosted in Estonia, Argentina, Chile, Colombia and Australia.

His arts education work includes participation in RED Artes Visuales de Medellín in Colombia, where he runs weekly workshop sessions for groups of schoolchildren aged 8 to 18. These sessions cover listening exercises, recording techniques, microphone construction, interventions, and instrument and kinetic sculpture building.
