My husband' s cardiologist is a facc. We are moving, and when we asked if he knew of a good one in nc, he said the facc would be good to look fot, because they have sat for the test nand keep current. That being said, he also told us some older drs. Have not sat for the test and are better than some facc ones.
Deathwatch beetle. Deathwatch beetle (Xestobium rufovillosum), an anobiid, or borer insect, of the family Anobiidae (insect order Coleoptera) that makes a ticking or clicking sound by bumping its head or jaws against the sides of the tunnels as it bores in old furniture and wood.
The adult male cicada possesses two ribbed membranes called tymbals, one on each side of its first abdominal segment. By contracting the tymbal muscle, the cicada buckles the membrane inward, producing a loud click. As the membrane snaps back, it clicks again. The two tymbals click alternately. Air sacs in the hollow abdominal cavity amplify the clicking sounds. The vibration travels through the body to the tympani, which amplify the sound further.
