There are some that believe that having components that have a frequency response that extends beyond what is commonly accepted as the limits of human hearing has benefits. Some of those benefits are sometimes attributed to having the device not working close to limitations, and therefore working in a more comfortable, less stressful situation. Another reason suggests, that it extends the range where back reflections occur, and therefore allowing more space for dissipation of those reflections that could potentially corrupt incoming signals working within accepted hearing range.
Hearing Damage over 20khz?
I own speakers that produce in excess of 40khz, yet the human ear can only perceive 20khz.
If something is uncomfortably loud we can hear, we know to turn it down but what if the frequency is out of our audible range?
Is it possible hearing is being damaged by something we can't hear?
I have read reports of people having ears ring after using speakers that can go beyond 20k, but I don't know if it's due to the sounds produced below 20k or above or both.
It would be horrible to learn I was damaging my children's ears or mine without knowing it.
