OMG...this is me too! Corner of Basel and East Canyon, brand new transformer within yards of my deck and I can hear it. It drives me crazy and I have severe Tinnitus...(that's a whole different subject) Having extra noises, pings, rings, buzzing, high pitch sounds is driving me nuts. I didn't think there was anything I could do. I'm so mad at this placement of this transformer...so incredibly close to my home.
