Portable air conditioning units get as loud as 55 decibels. When discussing how loud something is in dB, people are often referring to the dB Sound Pressure Level, which is often shortened to dB SPL. A noise level of 58 dB is not considered to be loud. So, for example, a noise level of 55 decibels is actually 10 times louder than a noise level of 45 decibels. That accommodates for 144.49 dB of signal-to-noise information. Loudness refers to how you perceive audible sounds. As a linear measurement, doubling the sone level is equivalent to doubling the loudness; quadrupling the sone value quadruples the loudness, etc. While the headphones themselves are great, what I found particularly interesting was a flyer included in the headphones packaging.
