Recordings involving cellular telephones or personal digital assistants (“PDAs”) are increasingly the source evidence in audio forensic examinations, compared to recordings originating with other devices such as hand-held digital recorders. On modern PDA cellular telephones recordings can be made either directly to the telephone or transmitted as voice mail messages. The current investigation focuses on differences in the two types of recordings in terms of dynamic range and linearity of levels. Such information can be important for characterizing the distance of sound sources relative to the microphone and are important for understanding transformation of recorded speech and non-speech sounds.

Archaeology is founded implicitly on the concept of the site, making a careful distinction between sealed sites—presumed to have complete temporal integrity—and the surface record, which is generally considered to be without chronological resolution. While most American archaeologists focus on reconstructing events and episodes at camps, pueblos, and villages, the authoer questions this distinction. Instead, he characterizes the archaeological record as an accumulation of many human events superimposed upon each other across time and distance.
