WTF is this threshold of pain at 1800-2500 Hz?

Any threshold of pain is going to be related to a particular sound pressure level, not a particular frequency.

The threshold of pain is the SPL beyond which sound becomes unbearable for a human listener. This threshold varies only slightly with frequency. Prolonged exposure to sound pressure levels in excess of the threshold of pain can cause physical damage, potentially leading to hearing impairment.

Different values for the threshold of pain:

Threshold of pain

SPL sound pressure

120 dBSPL 20 Pa
130 dBSPL 63 Pa
134 dBSPL 100 Pa
137.5 dBSPL 150 Pa
140 dBSPL 200 Pa

You're right, not the "threshold of pain", which refers to what you described. What I meant was simply painful frequencies, usually in vocals since they are in the center of the mix. I've found it's usually from 1800-2500.....but have also had it sometimes be anywhere from 1500-3500.

yeah I looked it up after talking off the top of my head, and it is in fact more around 3000 or so. But it'll vary from person to person, obviously. Those frequencies resonate with the size of our ear canals, so those frequencies are amplified, and can sound louder than others at the same volume.

If I can hear a painful frequency, I will just boost and sweep with an EQ until I find it. Wherever it is, I will cut until it fixes the problem. Doesn't have to be in that range, just from the artists I have worked with, it usually is. I would imagine it not only depends on the person listening, but also the person voice or instrument as well. I dunno
