Question about my hearing, I'm scared?!?

16, male. FOr some reason im really worried abuout my hearing. My dad asked me today if my hearings got worse, and I said i don';t think so. Its ahrd to tell whether things have gotten harder to hear, but my dad says I say Pardon, and can';t hear him alotta the time. Im terrified, what if i go deaf? Should i go for a hearing test? its harder ti say if my hearings got worse, but now i;m scared, what should i do, and how do i really tell if it has gotten worse?
