In this brief video, Bryan Johnson showcases a professional‑grade hearing system while explaining his personal hearing health. He reveals that his left ear suffered damage from childhood gunfire exposure without protection, resulting in a biological hearing age of 64, whereas his right ear remains relatively healthy. He compares his hearing curve to his 17‑year‑old son’s, noting that his own hearing drops sharply after 4,000 Hz while his son maintains near‑perfect sensitivity across the spectrum. Johnson mentions that he is undergoing experimental therapies aimed at regenerating the damaged left ear and that he regularly monitors his hearing performance with the device.

Here we have a professional grade hearing system. So I have hearing damage in my left ear because I shot guns as a kid and did not wear hearing protection. So my left ear is aged at 64. My right ear is much better. If you look at my age scores, my son 17, he has perfect hearing across all the spectra. With me, you get to 4,000 hertz and it just drops. And so this device, we're doing some therapies to try to regenerate my hearing capacity in my left ear. And so we're monitoring this on a regular basis.
