Although we have presented both dBA and dB sound level maps for the weekday daytime, weekday nighttime, weekend daytime and weekend nighttime, we now go a step further and look at the difference in the total sound and the A-weighted sound. This difference, we believe, can be thought of as what is not being captured by using the typically reported dBA. In areas where this difference is great (corresponding to the darker areas), we argue that additional sound metrics may be needed to get a truer sense of the sound levels. Do you notice any patterns with weekday daytime noise? Do you think the dBA captures sound in your neighborhood adequately?
