Frequency response display

1. A method for displaying a frequency response for a sound system design, comprising:

processing coverage map data for a listening area, the coverage map data comprising a plurality of samples;

computing frequency response data for each sample;

accumulating the frequency response data into a plurality of distributions; and

generating a statistical frequency response display based on the distributions, wherein accumulating the frequency response data into a plurality of distributions comprises representing each distribution as a histogram comprising a plurality of bins, each bin representing a range of sound pressure levels at a given frequency.

2. The method of claim 1 , further comprising normalizing the distributions.

3. The method of claim 2 , wherein normalizing the distributions comprises:

identifying a bin of the histogram having a largest value; and

dividing all of the bins by the largest value.

4. The method of claim 3 , wherein the largest value corresponds to a highest occurrence of a sound pressure level.

5. The method of claim 1 , wherein the plurality of samples of the coverage map correspond to locations of a listening area.

6. The method of claim 1 , further comprising dynamically updating the statistical frequency response display in response to a change in the sound system design.

7. The method of claim 1 , wherein accumulating the frequency response data comprises accumulating a distribution of spectral data at each sample in a coverage map corresponding to the coverage map data.

8. The method of claim 1 , wherein the statistical frequency response display represents the probability of achieving a given sound pressure level at a given frequency.

9. The method of claim 8 , wherein the statistical frequency response display plots sound pressure level on a y-axis and frequency on a x-axis, and superimposes the probability on the x-axis and the y-axis.

10. The method of claim 8 , wherein the probability is shown using colored shading, in which different colors of the colored shading each represents a different probability.

11. The method of claim 1 , wherein computing frequency response data comprises computing a sound pressure level of the sound system relative to a frequency for a predetermined range of frequencies.

12. A frequency response processing system, comprising:

a coverage map sampling unit that processes a plurality of samples from a set of coverage map data and computes frequency response data for each sample;

a statistics buffer that accumulates the frequency response data into a plurality of distributions; and

a frequency response generator that generates a statistical frequency response display based on the distributions, wherein the statistics buffer represents each distribution as a histogram comprising a plurality of bins, each bin representing a range of sound pressure levels at a given frequency.

13. The frequency response processing system of claim 12 , further comprising a normalizer that normalizes the distributions by identifying a bin of the histogram having a largest value and dividing all of the bins by the largest value.

14. The frequency response processing system of claim 13 , wherein the largest value corresponds to a highest occurrence of a sound pressure level.

15. The frequency response processing system of claim 12 , wherein the statistics buffer accumulates a distribution of spectral data at each sample in a coverage map corresponding to the coverage map data.

16. The frequency response processing system of claim 12 , wherein the statistical frequency response display plots a sound pressure level on a y-axis and a frequency on a x-axis, and superimposes a probability of achieving the sound pressure level at the frequency on the x-axis and the y-axis.
