Interpreters Need ISO Compliant Sound. Why?

Interpreters are performing all at once four separate tasks while the ordinary listener generally is doing just one. That is why an interpreter may find the sound poor when ordinary participants find it satisfactory. Why is this? Please click the gold button to see the explanation in my most successful video. I'm posting it again because good sound, and the injuries to interpreters due to bad sound (no RSI platform has ISO compliant sound), are such serious matters today.
