Hello richard beccarini
Welcome to HCM
The sound which you are hearing again and again of you, is nothing but Auditory Hallucination
. It has bizarre contents like erection can occur through positive emotions as excitement or derogatory remarks.
Hallucination is in simple term perception without stimulus, that is hearing sound without any source of sound or seeing any object when there is no object etc. It is the part of your psychopathology and you are on right medicine for this illness.
is a newer second generation anitpsychotic drug with good response. The effect will take at least 4 wks to come. If problem increases further visit your psychiatrist
Thanks and Take Care
