Abstract:
1. A method for producing an auditory alert that comprises sonic properties for an equipment operator wearing a headset prior to a presentation of the auditory alert to the equipment operator, the method comprising: measuring an at-ear ambient noise spectrum; separating the at-ear ambient noise spectrum into discrete, pre-determined frequencies; determining frequencies within the at-ear ambient noise spectrum that have relative minimum intensities; resetting the relative minimum sound intensity at each discrete, predetermined frequency exhibiting relative minimum intensity to a level that is equal to the higher of an actual intensity of each discrete, pre-determined frequency and an intensity of a next lower discrete, pre-determined frequency in the at-ear ambient noise spectrum minus 2.5 dBA for ⅓ octave bands and 7.5 dBA for full octave bands; and generating the auditory alert incorporating the enhanced relative minimum intensities.
