Lavalier microphones enable recordings from inside cavities and at extreme environmental conditions

Lavalier microphones (e.g., Sanken COS11, DPA 4060) were designed for unobtrusive body-mount use on performers, but their tiny form factor makes them suitable for unconventional placements — inside animal carcasses, insect nests, elephant watering holes, or submerged near amphibians. Their omnidirectional pattern reduces sensitivity to wind and handling noise, and models designed for stage use tolerate perspiration and humidity, making them effective in tropical environments. The DPA 4060 in particular is notable for surviving being trodden on by an elephant and returning to normal function within 10 seconds. Frequency response correction (the body-effect boost designed for clothing) should be considered when placing mics in free air.

Examples

DPA 4060 buried near an elephant seep in Zimbabwe: survived elephant standing on it. Lavaliers placed inside a dung beetle nest and a zebra carcass. DPAs on the surface of Everglades water recording snapping alligators.

Assessment

A recordist wants to capture sound inside a hollow tree at 35°C and 90% humidity. Justify selecting a lavalier omnidirectional mic over a small-diaphragm condenser, citing at least two specific properties.
