How Old Are Your Ears? (Hearing Test)👂
Nerve cells called "hair cells" pick up different frequencies and send them to the brain for processing. The hair cells tuned to high pitches are the first to encounter sound waves, so they experience more stress. Almost everyone can hear 8,000 Hz. People under 50 years of age on average can hear 12,000 Hz. And 15,000 Hz can be heard by people under 40 👂

This was one of the first signs I was old. I couldn't hear some of the high frequency sounds I could in my youth. It's interesting how the body deteorates with age. I wonder if we lose some of our sense of taste or touch as we get older too.
