text:  How do we know? I mean, that seems like a huge number. How do I know on my personal device what the decibel level is? So a good rule of thumb is 60-60. So 60% of your phone volume for no more than 60% or sorry, no more than 60 minutes at a time. Because one thing to take into account is that noise exposure is dose dependent. So we take doses of noise. Okay. Yeah. And over time, extra doses could lead to hearing loss.
