 That's an interesting link. Thank you. It provides a rough reference for hearing, but of course doesn't take into account the frequency response of your headphones or sound card.

The sound card for all intense and purposes for this test will be relatively flat, but headphones vary significantly, so a meaningful test will be calibrated against the headphones that will be used.

On a calibrated test I can detect -18dBm at 17.5 kHz, but on this one, with my own headphones (Sennheiser HD400) even 16 kHz inaudible below "0dB" whatever that actually is as it also depends how you have the volume set!

Anyway, useful for comparison.

You young 'uns out there should be able to hear 16 kHz down to at least -24 dB on this scale. (No cheating by turning the volume up!)
