Yes I'm an audio engineer so I have apps I use to detect microphone feedback during live events so I can EQ it out of the mains quickly. So if you hum a frequency it'll tell you what you're hearing, and everytime I hear the buzz and hum with it it's at 118-119hz (my wife said when I used multiple fingers it sounded like static and when I listened up close with my ear when using multiple fingers it sounded like multiple strings on a violin but very close in pitch)
I detected the audio frequency of the buzz sound and it is about 118-119HZ....👀
