    Human perception of sound, brightness, pain, etc. is always on logarithmic scale. It pays close attention to small signals and suppresses high-power signals. The value of a signal is mostly in the information it carries, not its intensity.

        How much louder than a whisper is a conversation? 10x? No, more like 1000x. How much brighter is it outside in the sun compared to inside your house? 10x? No, more like 1000x.

        Used this theory in recurrent neural networks to extract the volume-time-high price of Ethereum .. still in my early research but it gets rid of a lot of noise

        That is an interesting observation, however, it may be a built in / self-protective mechanism to insure the durability and sensitivity of the sensory mechanism and not related to signal, value, or intensity.

        An simple / good experiment with robust data would help formalize Cholett’s Law. Any thoughts on how to approach and test the validity of the information value claim?

        The intensity is part of the information it carries. Maybe closer to say that the value of a signal is neither in the intensity nor the information it carries, but in how it compares to previously encountered signals.

        It doesn't seem to apply to temperature. Going from 5°C to 10°C would be perceived as acutely as going from 25°C to 30°C. Perhaps because intensity is the main information being transmitted. Unlike sound where for the same decibels what matters is whether it's a lion or a car.
