WD HC550 18TB sound

Recently I buy a WD HC550 18TB and put it in my build. It is okay since last night, it is quiet so I can hear some noise which is like a tiny bass sound from my speaker or someone tap to a empty wood box or tap to wood table, but it is very small sound and it happen every 5 seconds

After a while I sure it is come from my new HDD. I know HDD creating sound is normal but I dont hear this sound ever before. I google it and I thought it is vibration sound. But I dont know what is vibrating sound like. Is it normal or my HDD has problem? Thank you
