    Does "Hi-Res" audio create noise pollution for pets?

    So I was just thinking about how "Hi-Res" audio tracks (192 kHz, 96 kHz, etc.) might be creating noise pollution for pets in people's homes. For instance, cats can hear up to 64 kHz and dogs 45 kHz: https://www.lsu.edu/deafness/HearingRange.html It's my understanding that what audio has been...

    The Complications of Earpads and Eartips

    I don't really have a simple solution, but I thought it was worth describing the problem as I see it... there are several things I think about when I'm about to buy a headphone or earphone, and they all relate to the interplay of fit/comfort and sound: 1. How will this headphone/earphone fit...

    Differences in power output of different types of amps and speaker resistances...

    I happened across this video on YouTube: I'm not familiar with John DeVore or his company, but it seems to me that he's implying there's some sort of conspiracy that started long ago between high-end audio magazines and equipment makers and how they list their specs so that people will spend...
