I was reading the liner notes in the new Beatles remaster box set, and apparently the few seconds of high frequency tone at the end of Sgt Pepper was intended to be inaudible to humans but amusing to dogs. I've always been able to hear it, even on the older CD release. Anyone else that can hear it? Does this make me a dog????

The tone is at 18 kHz, which is not outside the average human range of hearing.

As to whether you are a dog or not is left up to others to decide.
