Phase II recording involved sound sampling from an empty hive box.

As part of refining our IoT device, we’ve moved to testing microphone placement within an empty hive box. Using 3D-printed mic holders, we intentionally positioned the mics in four key areas: opposite sides of a frame, the top center of the hive (where most studies recommend placing mics), and deep near the hive’s primary entrance.

Our sound source, an iPhone 13, was placed on a vibration-reducing pad on the bottom board in two locations. The hive's lid was secured to replicate realistic hive conditions. We then conducted a series of recordings under different sound conditions, including white noise, ambient external sounds, a mix of white noise and external sounds, and even queen piping recordings, both with and without ambient noise.

The goal was to determine how each mic position captured these different sound profiles and assess the clarity of the recordings from each location. This testing phase was crucial for deciding which mic placements yielded the most accurate and informative data within the hive, setting the stage for the next round of experiments.

By experimenting with strategic mic placements, we're ensuring that future recordings of real hive conditions—complete with live bees—will provide us with the highest-quality data for monitoring hive health.
