It must be 16 kHz or higher.
I've always been able to hear that too, as well as some florescent lights. The tone from an NTSC TV probably comes from the raster scan frequency, which is ~15,734 Hz. Why do you say it must be higher than 16? -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=53636 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
