A frequent source of disturbance, tension, and annoyance is the noise from barking dogs, which may be highly grating.
For the purpose of fending off rodents and calming dogs, I blended a number of sound waves with a frequency that is above the upper limit of human hearing. I also included some theta wave sounds, which are frequencies between 4 and 7 hertz, and also included some 528 hertz waves, which are also effective for calming individuals down, in addition to certain sound waves within the range of human hearing.
I've played this sound on my laptop's tiny stereo speakers multiple times to test it out. Dogs in the area that are barking up to 10 meters away eventually quiet down. I hope it'll work for you too.
