Скачать или смотреть Measurement of radio/cellular device (Inside)

This measurement was taken inside of my living room. To take measurements I am using an app called "High Frequency Noise manager" for Apple iPhone which cost me $5.99. Using this app I am able to measure and plot graphs of the high pitch ringing sound I have been hearing since this radio device was first turned on. After measuring and observing this device for almost a year, I identified the waveform as a digital signal. The waveform pattern doesn't match natural sounds, and is not a solid sine wave tone like the sound is perceived as by the human ear. This means that it must be either radio or cellular in nature, and the reason I can hear it as a "tone" in the air is because they are broadcasting within the audible range as well as the range of my phone's microphone which is how I am able to measure this interaction. I am also including a link to my OneDrive for screenshots of more accurate measurements of this device.
