Well I have to say it is more than that. The revolution of music started longer than any of can remember. We all have a favorite singer. Rock and Roll, Country, Classical, Jazz, Rhythm and Blues, when we hear our song it either mellows us or it excites us. You want to know why don’t you? Well it has to do with the tone, the (frequency range). The year 1955 is the year that The International Standardization Organization made 440 Hz a tuning standard for music pitch. Before that it was 432Hz.
As your question why the change to a higher frequency? I will leave it at this, watch the videos, I think we all are smart enough to understand what has happened and how we can somehow get a bit of our life back. Also check out the last link, it really explains what happened and how it happened. Would it be nice to change the world, by the way we hear it.

The best definition, I have found is from Web M.D Here is a short paragraph.
Tinnitus (pronounced ti-ni-tis), or ringing in the ears, is the sensation of hearing ringing, buzzing, hissing, chirping, whistling, or other sounds. The noise can be intermittent or continuous, and can vary in loudness. It is often worse when background noise is low, so you may be most aware of it at night when you’re trying to fall asleep in a quiet room. In rare cases, the sound beats in sync with your heart (pulsatile tinnitus). http://www.webmd.com/a-to-z-guides/understanding-tinnitus-basics
I have had this condition for 19 years, some days it is okay and others it is nerve racking. I tried different method’s, Brown Noises, White Noise and even Pink Noises. So I went on a web search, for on-line noise generators, I found two which I think works well enough to get me through the day. One is from AudioNotch http://www.audionotch.com/app/tune/ the other is from the American Tinnitus Association http://www.ata.org/sound . I use both, Audio Notch give you a wide range of frequency’s to match what you are hearing. The program from the American Tinnitus Association has a mixture of sounds.. I hope this helps
