The ninety-six objects in this inventory are sourced from earwitness interviews Lawrence Abu Hamdan conducted as well as from trial transcripts across the globe. After SFX explores the ways we remember sound and the ways in which cinematic sound effects have created a collective acoustic unconscious. What is revealed is our difficulty in describing these memories when precision is vital. The objects listed here stand in for a missing sonic vocabulary, a language we do not yet speak.
