Rheem RGRM 105,000 BTU 95% 2-STAGE FURNACE Variable Speed and my furnace is very loud.. Model RGRM10EZAJS

the air is coming more.. not sure, what I have to do.. lot of noise..
Can you help me the steps to reduce the noice..

I have a 1961 furnace replaced yesterday, the old one is very quite, but this one is to noisy -- and also, if I sit beside the vent, it is hurting my ears..

Is it a speed issue. Old one has a 100 BTU and replaced with 105 BTU..

Night also coming so loud and the air from vents are noise with forced air..

Can we decrease the air flow?
