The first batch of reviews covering models from Audio-Technica, Creative Labs and Monster Cable appears in the current issue of Playback playback. It occurred to me that you might enjoy learning how I tested the headphones and then, if you like, trying some listening experiments of your own. At first blush, you might think it would be easy to test Noise Experiment III - Von Safeld - Noise Experiments phones. Just find a noisy environment, plug them in, and have Noise Experiment III - Von Safeld - Noise Experiments it, right?
To meet these goals, I decided to set up two systems: a reference noise generator, and a reference headphone playback system. Here Various - Friday - Original Motion Picture Soundtrack a couple of points worth nothing about the noise generation system. When you listen to noise-cancelling headphones, then, you get a more accurate picture of how the various noise cancellation circuits work and how effective they are.
Second, the Mirage speakers are omni-directional, meaning that they have very even power response throughout the room. As a result, noise more or less comes at you from every direction, just as would be the case in a plane, train, or bus. Fourth, the NuForce preamp has a very finely graduated and clearly marked volume control that allows exactly repeatable volume settings during noise susceptibility tests.
Some comments: Is this a way better headphone playback rig than most people own? Test Approach: I began by firing up the noise generator system and setting volume levels to approximate those within an airliner in flight pretty loud, but of course not deafening.
I noted the volume settings on the NuForce preamp so that I could re-create the same noise levels for future tests. But for use in environments where moderate to high levels of noise are present, noise-cancelling designs are just what the do.
