Espinner noise comparison

I filmed a long video comparing the noise levels between three espinners, then realised it was pointless, as while these two both had the same noise measurement in decibels, one is obviously far quieter than the other. Sure, phone app dB meters aren't highly accurate, but there's more than that going on here... stay tuned for a blog post on the subject, and a comparison of the Hansen Minispinner Pro, EEW 6.0, and Daedalus Sparrow, without talking about the noise level in decibels!
