1. A method to determine a location of an audience member, the method comprising:
- generating a correlation analysis result based on correlating first audio samples from a stationary audio detector with second audio samples from a portable audio detector carried by the audience member;
determining via a neural network the location of the audience member based on the correlation analysis result; and
crediting media presented via a media delivery device with an exposure credit when the audience member was located within a threshold distance of the media delivery device as indicated by the location of the audience member.

12. A method to determine a location of an audience member, the method comprising:
-
generating a correlation analysis result based on correlating first audio samples from a stationary audio detector with second audio samples from a portable audio detector carried by the audience member; and determining via a neural network the location of the audience member based on the correlation analysis result, wherein generating the correlation analysis result comprises; determining a first sum of squares of each audio sample in the first audio samples; determining a second sum of squares of each audio sample in the second audio samples; multiplying the first sum of squares by the second sum of squares to determine a first product; determining a square root of the first product; determining a third sum of second products between corresponding audio samples of the first and second audio samples; and determining a correlation coefficient associated with the first and second audio samples by dividing the third sum of the second products by the square root of the first product. - View Dependent Claims (13)

16. An apparatus to determine a location of an audience member, the apparatus comprising:
-
a correlator structured to generate a correlation analysis result based on correlating first audio samples from a stationary audio detector with second audio samples from a portable audio detector carried by the audience member; and a neural network structured to determine the location of the audience member based on the correlation analysis result, wherein the correlator is to generate the correlation analysis result by; determining a first sum of squares of each audio sample in the first audio samples; determining a second sum of squares of each audio sample in the second audio samples; multiplying the first sum of squares by the second sum of squares to determine a first product; determining a square root of the first product; determining a third sum of second products between corresponding audio samples of the first and second audio samples; and determining a correlation coefficient associated with the first and second audio samples by dividing the third sum of the second products by the square root of the first product.
