And looking one step before the ear: there are very, very few loudspeakers or headphones that can accurately reproduce 15,000 Hz and above. So even if you are generating them in analog or digital, they are getting filtered by the speakers long before reaching your ears.
Good point. A quick survey of heaphones available at a local electronics store reveals that the top end varies between 13kHz and 30kHz. I guess speakers are going to have an even more varied response.
Did they tell you in dB range of the frequency response? My laptop speakers do 1-1,000,000 Hz (+-100dB). Obviously, the important part there is the +-100dB. Generally, a decent frequency response is +-3dB. Many manufacturers use +-6dB because it makes them look much better. And many just make up the numbers.
If they don't tell you what the +-dB are, they are probably lying.
