The Guardian reports that in the Dordogne region of France, a judge ruled that homeowners must drain their pond to eliminate noisy frogs bothering their neighbors. On one side of the matter is a useful habitat for local fauna, and on the other a very tired neighbor.
The problem is that during mating season, the frogs’ calls have been measured at 63 decibels (dB) at the neighbors’ window. Sound pressure levels as low as 30-35 A-weighted decibels* can disrupt sleep. The decibel scale is logarithmic, so 63 dB isn’t just twice as loud as 31.5 dB but orders of magnitude greater. (I would also note that in psychoacoustics the word loudness has specific meaning, and here I am just using it as we use it in everyday speech.)
The situation is complicated by the fact that some of the frogs belong to endangered species, and the small pond serves as a local watering hole for other animals, including deer and wild boar.
Nature lovers are concerned, and the case is being appealed to France’s highest court. Keep an eye here to find out how it ends.
