Many DC regions have listened to cc to calls in recent weeks. Some people ate eaten. However, a local man recorded their bark and identified the mating bark.
Before retiring about a year and a half ago, Grimes spent more than 30 years as a production manager for Wolf Trap’s Burns.
A sound and lighting expert, Grimes is also a musician and has the specific skills to answer this question.
“Every sound has a frequency, which means that every sound is a vibration,” Grimes said.
Grimes found the frequency with the help of modern technology.
“It’s very consistent. What you hear is the noise of 1.3 kHz, which is the E in the sixth position of the piano,” he said.
“The overtones that have occurred in the last few weeks have culminated in F major in F major, which means that the combination of these two notes creates a kind of minor scale.”
He also recorded the bark of c. Maximum volume so far: 97 dB.
“When I hit 97 decibels, the average was about 101 decibels, which was as loud as a rock band.”
Grimes pointed out that 97 decibels violate the law in many places.
“They are breaking the law, but they are paying the price,” he joked.
Grimes also states that its volume corresponds to heat. The hotter the day, the louder they sing.
