[Closed] Rear wheel noisy

My rear wheel is noisy whenever it goes over rough stuff. It doesn't seem to effect anything but it's annoying especially on a descent when it makes a mega racket. It makes a loud noise every time it hits anything.

I've took it to a mechanical for wheel bearing replacement, tightened the cassette, tightened the spokes (as there were a few loose). Still not made a difference.

I notice at around the same time my rear wheel has stopped 'ticking' when free wheeling - I don't know if this could be related ?

Anyone know what the cause could be ?

The bike is a Specialized Camber Evo 2015
