What's In a Sound?

There is a recent, and rather funny, debate going on in the Internet world about whether a person hears the world "laurel" or "yanny" when a particular sound wave is played. Apparently, the science behind it is that depending on the frequencies of sounds that people pick up,they may be  inclined to hear different sounds or make out different words. While this kind of experiment has people scratching their heads and disagreeing with each other, it is an interesting experiment in the way people disagree and even become frustrated when they are unable to "hear" what the other hears.
  A lot of our arguments may very well be based on differences in the "frequencies" with which we are hearing things. This is both literal and metaphorical. For example, how often have I thought to myself, "I don't know why this person behaves this way", not realizing that I am operating from a completely different framework and mindset from the other. It's hardly that I am right and the other is wrong; only that we thinking and acting from different frames of reference which don't happen to meet in a congruent way.
  Part of the miracle of music is the ability for two very different sounds to resonate: meaning that they meet in a certain place that might create a third "sound" or reverberation which is qualitatively more than the sum of the two parts. When the two people are willing to see past their differences (or at least stretch to acknowledge differences), the resonance can be captivating and beautiful. "Resonance" does not emerge because the sounds we are making are exactly identical: rather, it emerges when the two different sounds are able to create a new space between them which allows for more permutations  than what a single sound could produce. To go back to the example of the two words that people can hear from the same sound: what if it were the case that one is not the "true" sound after all, but that both sounds are just emanating from particular conditions of the mind? Is one sound "less" real or true than  the other? Can the two words somehow co-exist?
