The cricket as a thermometer
TL;DR
Cricket chirp rate correlates precisely with ambient temperature
Dolbear's Law, published in 1897, established that snowy tree cricket chirp rate is precisely correlated with temperature (count chirps in 15 seconds, add 40, and you have the temperature in Fahrenheit to within 1-2 degrees). This demonstrated that acoustic signals can encode environmental information with remarkable precision.
For organizations, this illustrates how rhythm and cadence in communication carry information beyond the explicit content. The regularity or irregularity of organizational communications signals health, stability, or distress.
Key Findings from Dolbear (1897)
- Cricket chirp rate correlates precisely with ambient temperature
- Formula: Temperature (F) = chirps in 15 seconds + 40
- Accuracy within 1-2 degrees Fahrenheit
- Acoustic signals can encode environmental information
