This two day workshop, guided by Martin Howse, will equip participants with a range of practical techniques for audible, forensic examination of both the material and immaterial. A series of experimental situations will be constructed, investigating materials through audible excitation, transformation and detection including ultrasound, light modulation, surface playback, and electrochemistry. The workshop will also examine classical techniques for the study of electronic voice phenomena (EVP), and suggest new detection strategies.
