Dripping Sound in Kitchen Drain

[nr]

My kitchen drain (one with the disposer) has an intermittent sound that sounds like water dripping but from a distance (not in that drain). I don't use the dishwasher, so I don't think it's from that and I haven't found any water leaks or dripping faucets or toilets.

Any ideas what this might be and how to correct it?

Many thanks for any info.

House plumbed with PVC/ABS drain piping? If so, residual water draining will produce faint (or loud) dripping noises.

If you don't find evidence, may be normal.
