1. A method for sound analysis, comprising the steps of:
- transforming, in a computing device, a sound print into a frequency domain in a memory to generate a frequency spectrum;
identifying, in the computing device, a plurality of signatures in the frequency spectrum, wherein the signatures each comprise a maximum amplitude shift that is less than a predefined threshold over a predefined frequency band;
identifying, in the computing device, a plurality of frequency ranges associated with the signatures in the sound print; and
cross referencing, in the computing device, a plurality of frequencies associated with a profile with the frequency ranges to determine if the profile is applicable to the sound print.

Abstract
Disclosed are various systems, methods, and programs embodied in a computer-readable medium for sound analysis. The sound analysis involves transforming a sound print into a frequency domain in a memory to generate a frequency spectrum. A plurality of signatures are identified in the frequency spectrum. Also, a plurality of frequency ranges associated with the signatures are identified in the sound print. The frequencies associated with a physiological profile are cross-referenced with the frequency ranges to determine if the physiological profile is applicable to the sound print.
