Frequency hearing drop Options

[eahm]

"Hello doctors/experts,"

I read that the ability to hear high frequency sounds drops with time and age and I am aware that we have a range and I also saw graphs and documents about it.

My concern is about how the drop appears, does it change from where one lives? How much and how fast can the time/age drop? Does it depend to humidity? Weather (too cold, too warm)? Altitude? Bad habits (alcohol/beer, whisky etc., smoking/cigars etc.)? Most important, fatigue/not to much sleep (and probably still related to the weather being too warm)?

I am 30, can it be temporary and go back up during winter?

It's not a matter of life and death, I actually don't really care, the music is still good to me and if age does this it's ok but I was able to hear up to 17Khz let's say 5-6 months ago and now only up to 13Khz. Here in Phoenix 5-6 months ago was cooler than this very hot summer that's why I'm asking about the weather possibility. I've been in Arizona 6 years but I am not from here, I am from a small mountain town from the center-north of Italy, I have no idea what the desert can do to a person.

If anyone can answer, thanks.

The funny part is your brain/ears continually adjust to environmental conditions throughout the day. For example I drive truck for a living, after 12 hours in a noisy semi I cant hear tones above 12khz, yet under normal conditions I can hear 17khz easily. Yet my music still sounds the same. Scientific studies have shown that even under normal conditions we start to experience high frequency loss in our 30s and that normal adult hearing is more like 30-15khz. But take heart! There are only 8 notes between 10khz and 20khz ie a single octave of harmomics/digital noise hardly audible to dogs or bats let alone humans during music playback. Its not worth obsessing over since its an unavoidable fact of life. Granted its still adviseable to wear earprotection in noisy environments to prevent long term damage in the important ranges.
