Nothing to worry about, if the wheel looks straight.
If you ping all the spokes one by one, you may find one that rings
"flat" or not at all. If so, you could ask your local bike shop to nip
it up a bit tighter. It's a small job. If you remove the wheel from
the frame, and remove the tyre and tube, they might not even charge you
for a 2 minute job tightening a couple of loose spokes.
A spoke cycle wheel is a dynamic structure like a suspension bridge.
The load on each spoke changes as the wheel spins. The spokes are
under slightly varying degrees of tension anyway because no rim is
absolutely perfect.
Each spoke crosses three others, coming into physical contact with two
of them. As the loads change, the spokes may rub slightly which can
make these noises. Also, the spokes will expand or contract with
changes of temperature, and the surfaces will become more or less
slippery with changes of humidity.
Nothing to worry about.🙂
