If the level at low frequencies is so high you hear obvious distortion, then run the tests again at a lower level. Likewise, if all of the tones seem fairly soft, you'll need to raise the overall level. Common sense will tell you when you're within a useable range. You may find that some low frequency tones cause windows and furnishings in the room to vibrate and rattle, so you'll need to fix those before you can measure the low frequency response accurately.

Also, be sure there are no other noises present when running the test, such as the rumbling of a furnace or air conditioner. Likewise, be careful not to make any noise yourself, or tap your foot, or breath loudly near the microphone capsule, while reading the meter levels. The tones are spaced at 1 Hz intervals, with ten tones per CD track, and the layout is shown below under Track Contents.

At most frequencies you can hear the transition from one tone to the next, but you can also use the CD player's time readout if needed. For example, Track 10 plays through Hz, so if the time readout says 23 seconds that means you're 3 seconds into the Hz tone.

If you get lost, just rewind to the start of the current track and resume from there. The close 1 Hz spacing also makes it difficult to squeeze that many tiny dots onto the graph paper at the upper end of the range, above about Hz.

I can't even connect to the server. Nevermind, I got it. I had to change my DNS servers. Once again, I can hear the 22kHz tone on both my headphones and my speakers. I have to turn the volume up a little louder than normal, but I can hear it. I can hear kHz without turning the volume up. My HF sensitivity starts to drop off after 18kHz.
