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. The different audible signals have been observed to efficiently help a human locate emitting devices that are either in close proximity to the user or that are a large distance from the user. Additionally some examples emit audible signals that have been observed to efficiently help a human locate emitting devices that are located inside a sealed enclosure, such as a box. Some audible signals include audible noise processed by band-pass filters with spectral peaks at about 500 Hz, 4 kHz, and 8 Khz. Such audible signals are alternately emitted in time with audible signals having simultaneously occurring fundamental tone frequencies that each have harmonic components.
