Far from. I was just in the ordinary doctor's office - she had me turn my chair and face the window, that was it. Doc and nurses were talking in the hall, trucks were audibly rumbling by on the street (I flinched once or twice thinking they were very low frequency beeps), and the AC was causing a general white noise that made it even harder to hear. The only thing that helped was I could usually hear the left or right speaker sort of click on before the tone, so I usually knew which ear to listen really closely with.
