    We need an engineer to invent a decibel-controlled TV so that programs don't try to damage my hearing with loudness, AND so I can hear the soft sounds. About 7.0 would be great, but it needs to be adjustable.

    "Because it's nicer when things get more complex."

    This video has not only helped me understand dB better but the above quote has helped me understand why my dad (an electrical engineer) was the way he was. 😉
