New kitty might be deaf?

I recently adopted a 3 month snowshoe Siamese mix from the shelter and he's got pretty blue eyes. On the health reports they out down possible hearing issues. When I call his name he rarely reponds and only sometimes I see his ears flick showing he heard the noise. But when he is walking and someone makes a loud noise he jumps like a foot in the air. Could my kitten be deaf and what do I do if he is?

Deafness is more commen in presian cats having blue eyes or odd eyes with white coat..
Siamese hav very low chances of deafness

Well he's not full Siamese, and he's got blue eyes with a mostly whiter coat

Yaa i can b.
Coz 75 prcnt blue eys wid white coat are deaf..

Just do a litter work,when he r she is sleeping clap loudly near his ear and check its behaviour...

Alright thank you. I've been doing a bit of testing. Like when I snap when he's walking past he doesn't even notice. But any really loud noise he jumps.
