ACOUSTIC OBJECT LOCATING SYSTEM USING TRIANGULATION METHOD

In this paper we study the acoustic object locating system using triangulation
method. This system consists of a set of acoustic sensors aligned in a straight line
with equal distance apart. The sound intensity is measured by the acoustic sensor at
different positions. Since the distance between the source and the sensors vary, the
location of the source can be determined by the discrepancy of the intensity measured
using triangulation method. The location of the source is then displayed on the plan
position indicator. This report will be discussed about the background study, problem
statement, objectives, and scope of study. In Chapter 2 we derive the key formula for
the coordinate of the source of acoustic object. We then design the circuit based on
the underlying concept. In Chapter 4, we apply programming in the system and show
how the coordinate of the source will be displayed on the plan position indicator.
