Siege Ballista produces painful to the ear robotic sound

I am trying to raise awareness where I can. I already posted in the skill feedback forums. Apologies for the reposts but I find this issue to be quite problematic for Siege Ballista

When you use Multiple Totem Support and summon a couple of totems (in my case 7), whenever they start shooting simultaneously the sound effect stacks on top of each causing an incredibly annoying and borderline deafening sound. Its especially noticeable when you stand directly next to the Ballistas while they shoot at a single target for example a boss.

See the short youtube clip for an example.
