Listen to your arm with no sound from the speakers. Almost all arms will have a measure of sound coming from the arm itself, ie acoustic noise generated from the cartridge which is transmitted to the arm tube and then to the air. Sometimes this is known as needle talk. Generally the more compliant the cartridge, the less needle talk there is, which is why a lot of arms are ok with high compliance moving magnets, but have issues with low compliance MCs, (although there are other factors)
If your arm suffers from this, then other aspects such as feedback from the speakers or vibration from the floor via the turntable will exacerbate it.
If the armtube vibrates/resonates then that is the source of the problem. Where the vibration comes from is secondary, though removing it obviously will help, and turntable positioning and mounting is important.
