I had the opposite problem when I lost my bluetooth headset. It had been over a week but could not find it so I turned bluetooth on my cellphone and called myself. I turned it to headset mode and started walking around tapping on things until I got close. I ended up tapping on the china cabinet and it got louder. I was able to narrow it down to a shelf then I found it.
