That's not true for me, I can hear higher frequencies just fine. It can cause problems sometimes! Besides the usual annoyances like transformers in old CRTs, there's a video game whose soundtrack has these horrible piercing tones left in, and I've only found a few other people complaining about it online. Most—including the composer, I assume—can't hear them, so are unbothered.
