Wow, 26Khz at 110 dBSPL? That's just stupid. You might as well argue that incidental exposure to wifi is certainly fatal because you wouldn't survive being cook

Wow, 26Khz at 110 dBSPL? That's just stupid. You might as well argue that incidental exposure to wifi is certainly fatal because you wouldn't survive being cooked inside a microwave. 110 dBSPL represents thousands of times more energy (in watts) than you could plausibly expect in any musically derived ultrasonic content played at a volume level which doesn't pose a significant risk of permanent hearing loss. At such insane power levels, obviously nobody will be hearing the actual frequency but rather sub-harmonics and/or other physical sensations derived from that moronic level of sound pressure.
