Forensic Sound Analyses of Cellular Telephone Recordings

By: Dr. Durand R. Begault

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.

By: David Smith

Pocket dialing occurs when a mobile phone's touch pad is pressed by something in a person's pocket or purse, or, if the person happens to sit down a certain way, a part of their anatomy. If the pressed key or screen surface area is programmed to dial or redial a telephone number, a call occurs. This call often goes undetected by the phone's owner. Some phones are more prone to this phenomenon than others.
