Ess Sounds and Teeth Whistling

Recently, my tolerance for people who overextend their ess sounds, push consonant sounds through a gaggle of spit behind their teeth, and whistle their consonants through their teeth and/or dentures has been at an all time low. On bad days, it's physically painful for my ear drums and makes me dizzy.

I'm looking for ear plugs that will block this, I've tried Loop and they made the sounds worse, I have ANC over ear headphones and they still let the sounds in ( and when its people in meetings or through a webex for work this doesn't help )

Any advice or ear plugs that specifically block these high frequencies?
