Assault with extreme high frequency. Barry Eghanian the installer of alarm system on May 20, 2016 at 3103 160th St Surrey B.C. used an extreme high frequency pitch during testing knowing a cleaning contractor was in an enclosed area being the walk-in closet and bedroom. Barry was preturbed that another contractor was working the same day. Alarm apparatus being tested and installed was set off at an extreme high pitch where Dana's job start was vacuuming the enclosed area. The frequency stunning not enabling a quick exit from the enclosed area had impact on eardrum. I Dana confronted Barry and again confronted him in the presence of the home owners. The home owners brought to my attention Barrys complaint of the vacuum as well as Barrys complaints of the twin baby boys. Following the assault with high frequency Barry unplugged vacuum versus communicating. Four days following my eardrum continues to ache. What action will be taken by Technique Alarm L.T.D. to prevent eardrum injury to others?
