There's a lot to the subject of workers' vocal signals. An interesting one is when competing waggle dancers are head-butted to stop- it comes with a sound. (Seeley's work )
If you closely examine a worker comb, you'll notice that the top of every cell is round, and the hexagonal starts below the rim. Using a magnifying device, you'll see that the material on the rim is propolis. Piping on the rim may enhance the propagation of the signal. When engineering for soundproofing, we would separate adjoining materials to stop the vibrations and resulting noise transfer. Therefore, a solid propolis web is a great transmission medium. If done at the right frequency, piping, quacking, or whatever sound they make freezes bee movement on the comb for a moment, so it's important that the single is felt or heard. Queens about to emerge are suspected of locating other queens with sounds that freeze bees. Maybe the way a sound propagates and is sensed by the piping queen, while the surrounding bee population is motionless, helps her locate the cells of rivals' per-emergence, so she can dispense of them in a hurry.
