Abstract
Audible signals are created and emitted that provide a human user with improved sound localization cues to quickly and efficiently find the emitting device. Different emitted audible signals are sequentially emitted in response to receiving an activation signal. The different audible signals have been observed to efficiently help a human locate emitting devices that are 1) inside a sealed enclosure, such as a box; 2) in close proximity to the user; and 3) that is a large distance from the user.
