As someone who works with speech content, this seems unusual. Typically, low frequencies are reduced because there's not much useful voice signal there—for example, NPR typically rolls off frequencies below 250 Hz.

Thanks for your viewpoint!

Here's something concrete: the first phrase in the video ends with "small demonstration", but starting with the second instance, I distinctly hear "sall" instead of "small". In the version with the noise, the "m" sounds like an aberration of the noise and is detectable. With the noise removed, the "m" is replaced with a blip that sounds like an encoding error.
