Frequency analysis of simulated snoring sounds using Burg's estimator [acoustic, flow and pressure analysis]

The authors present a system for the acquisition and analysis of acoustic, flow and pressure signals which are generated during snoring. Signal acquisition is handled by a commercial A/D converter, while analysis is done by a series of routines written in C and the MATLAB signal processing environment. The system has been evaluated using normal subjects, while ongoing studies are being done on real patients.
