Apparatus and method for locatable encoding alarms which increase the awareness of and locatability of objects, even for sight or hearing impaired individuals. The apparatus emits preferably a plurality of intermittent complex multiple frequency encoded noises at ear intensities less than 150 dbA, when measured at 10 cm from the source, which enhance listeners' conscious or subconscious abilities to estimate both the distance to the object from the listeners and at least two relative angles between the listeners and the object. The plurality of intermittent complex multiple frequency encoded noises include noise having at least in part primary frequency less than about 1.1 KHz and noise having primary frequency in the range of from about 4 KHz through about 12 KHz. Additionally, the apparatus provides encoded light, preferably an encoded, near monochromatic, coherent, pulsed light of less than 5 milliwatt intensity having primary output wavelengths in the range of from about 380 nanometers through about 780 nanometers, the light emitted by the object being encoded with balanced and selected saturation purity, interference, chromaticity, pulse duration, luminous flux and coherence that enhance viewers' ability to consciously or subconsciously estimate both the distance to the object and at least two angles between the viewers and the object, resulting in heightened alarm, awareness, and locatability for a large percentage of human beings.
