My son was really early with physical milestones and late with verbal. I was also concerned about his hearing around the same time. His pediatrician saw fluid in his ears from a recent virus, said it was likely nothing to be concerned with, but referred us fit a hearing test to be done after a trip abroad. When traveling, he started babbling like a mad man. He was 10 months. He spent about a week of the trip with a very verbal 8 month old, and I think that helped. We cancelled the hearing test. His babbling didn't advance much beyond a few words, and at his 18 month check up, his pediatrician said she'd talk about next steps if he didn't have 25 words at his 24 month check up. Well, we traveled abroad again at 22 months, and he literally started speaking in 4-5 word sentences overnight. Apparently my father was the same. Just waited until he could get it so together

My son's pediatrician was blown away by his language at his 24 month check up, and he went from being the least verbal of his peers to the chattiest. He's 28 months now and he's communicating very well.
Language guidelines are important, but they're just guidelines. I'd communicate with a pediatrician, to ease worries, certainly, but know it's normal where he is now. Get him around chatty kids, sing a lot of songs, narrate what you're doing, read a lot, and he'll get it. I'm a firm believer in their brains focusing on mental or physical in phases, so he's probably just now interested in moving around right now
