Car have noise ( very light bearing sound) during acceleration at certain speed

Just got fwd and aft brake pad replaced because of worn out. Fwd is original Honda, aft is third party.
Notice when I step on the accelerator, at certain speed, there is a slight bearing sound ( not sure from which side ).
This noise disappears once after acceleration, I noticed at maybe 40km/hr.
1) Could it be new brake pad changed? Need some time to seasoned?
2) Technician was not careful during replacement?
- brake pad not align properly? Brushing some other parts?
- or the need wheel alignment / balancing after brake pad changed?

Honda civic 07 FD series, 1.6L auto. 76000km
