When Hell is the noises that other people make! Sniffing, gulping, lip smacking, loud chewing, jaw clicking, noisy breathing, slurping, licking fingers. Aaaaaarrrgggghhh! There are certain individuals on this planet, and the author of this book is one of them, who live a nightmare. This nightmare occurs every day, and it can occur in any place where there are other people. The triggering sounds can lead to anger, frustration, rage, depression and isolation. The condition has led to relationships breaking up. It has led to physical assaults. It has resulted in the loss of employment. It may have even led in at least one case to homicide. The nightmare has a name: 4S, or Selective Sound Sensitivity Syndrome. This little handbook is for those who suffer from 4S. It will also help clinicians and the relatives and friends of sufferers understand this syndrome which can so blight a person's life.
