Blind Testing a 15 kHz Upper Hearing Limit - Audio Check

The first one plays back full range white noise, with frequencies extending up to 22 kHz. The second file plays back a low-pass filtered noise, with no sonic content above 15 kHz. Listen to both files: if you think you can hear a difference try the test below, otherwise pick a lower cutoff frequency at the top of this column. The Test

While you may not hear above 15khz, the overall effect on the music can be significant. After decades of working on my system, and own Heils and other planar speakers I realized that the real high frequency has a profound impact on the overall sound quality. I have not fiddled with measuring up that high. But a cut off sounds artificial.

If the sound of the voice itself resembles old telephone lines, it has been treated considerably more badly than being filtered to a bandwidth of 10kHz (what is needed for resampling to 22kHz). An actual telephone line limits the frequencies to 0.3 to 3.4 kHz, and coarsely matches 8kHz sample rate. I suppose the root problem is one of these:

Digital Audio Basics: Audio Sample Rate and Bit Depth

Most people lose their ability to hear upper frequencies over the course of their lives and can only hear frequencies up to 15 kHz–18 kHz. However, this “20-to-20” rule is still accepted as the standard range for everything we could hear.
