| You probably half to be in a half asleep state for any of these to work, just my theory I guess, not really sure how it works, and I haven't tried it yet, you have to have a FLAC or VLC program to hear them, but I heard VLC player crashes sometimes. |

| quote: | | Binaural beats are auditory brainstem responses which originate in the superior olivary nucleus of each hemisphere. They result from the interaction of two different auditory impulses, originating in opposite ears, below 1000 Hz and which differ in frequency between one and 30 Hz (Oster, 1973).For example, if a pure tone of 400 Hz is presented to the right ear and a pure tone of 410 Hz is presented simultaneously to the left ear, an amplitude modulated standing wave of 10 Hz, the difference between the two tones, is experienced as the two wave forms mesh in and out of phase within the superior olivary nuclei. This binaural beat is not heard in the ordinary sense of the word (the human range of hearing is from 20-20,000 Hz). It is perceived as an auditory beat and theoretically can be used to entrain specific neural rhythms through the frequency-following response (FFR)--the tendency for cortical potentials to entrain to or resonate at the frequency of an external stimulus. Thus, it is theoretically possible to utilize a specific binaural-beat frequency as a consciousness management technique to entrain a specific cortical rhythm. |

Binaural beats can easily be heard at the low frequencies (< 30 Hz) that are characteristic of the EEG spectrum (Oster, 1973). This perceptual phenomenon of binaural beating and the objective measurement of the frequency-following response (Hink, Kodera, Yamada, Kaga, & Suzuki, 1980) suggest conditions which facilitate entrainment of brain waves and altered states of consciousness. There have been numerous anecdotal reports and a growing number of research efforts reporting changes in consciousness associated with binaural-beats. "The subjective effect of listening to binaural beats may be relaxing or stimulating, depending on the frequency of the binaural-beat stimulation" (Owens & Atwater, 1995). Binaural beats in the delta (1 to 4 Hz) and theta (4 to 8 Hz) ranges have been associated with reports of relaxed, meditative, and creative states (Hiew, 1995), and used as an aid to falling asleep. Binaural beats in the alpha frequencies (8 to 12 Hz) have increased alpha brain waves (Foster, 1990) and binaural beats in the beta frequencies (typically 16 to 24 Hz) have been associated with reports of increased concentration or alertness (Monroe, 1985) and improved memory (Kennerly, 1994).
Passively listening to binaural beats may not spontaneously propel you into an altered state of consciousness. One’s subjective experience in response to binaural-beat stimulation may also be influenced by a number of mediating factors. For example, the willingness and ability of the listener to relax and focus attention may contribute to binaural-beat effectiveness in inducing state changes. "Ultradian rhythms in the nervous system are characterized by periodic changes in arousal and states of consciousness (Rossi, 1986; Shannahoff-Khalsa, 1991; Webb & Dube, 1981). These naturally occurring shifts may underlie the anecdotal reports of fluctuations in the effectiveness of binaural beats. External factors are also thought to play roles in mediating the effects of binaural beats" (Owens & Atwater, 1995). The perception of a binaural beat is, for example, said to be heightened by the addition of white noise to the carrier signal (Oster, 1973), so white noise is often used as background. "Music, relaxation exercises, guided imagery, and verbal suggestion have all been used to enhance the state-changing effects of the binaural beat" (Owens & Atwater, 1995). Other practices such as humming, toning, breathing exercises, autogenic training, and/or biofeedback can also be used to interrupt the homeostasis of resistant subjects (Tart, 1975). |

now all you need is a way to produce that low of frequency . .
sorry, you're home stereo ain't gunna cut it |

holy that cd is awesome. just got it off of torrentspy...
I can't do it home alone though...it's just too weird and sounds like an alien is going to come in my room and shoot me with a plasma gun or something. |

I listened to that CD (through the brand new Sennheiser EH-150 I just got today, I may add :D ) for a good 45 mins to see if it changes my mood or induces any type of effect. Nothing happened, expect that I kept yawning heavily and in general, felt a bit sleepy. Either I got bored listening to the monotonous sounds or it induced the effect of sleep in me. Dunno.
There's research evidence that binaural beats work. The working perhaps also depends on the right conditions, mental states etc. This stuff should be interesting. :) |

this is interesting but stupid because few people are going to have equipment that can produce the frequencies needed for these effects. Headphones for instance don't have that low of range, so the only thing you'll be hallucinating is that there is anything going on at all.
Now in a room with proper monitors, maybe...
EDIT - I misunderstood this concept when I first read it. I no longer agree with the above statement.
I am also very interested in low frequency neural responses and have even heard stories of factories and things generating low frequencies that have caused residents nearby to complain of an unsettling feeling, as if their home is haunted. |

My understanding is that the requirement of having stereo headphones is this: one cup plays frequency X and one cup plays frequency Y. Part of the frequencies are similar and thus cancel each other out - leaving you with the difference/otherwise undetectable frequency. So, in effect, all you need are stereo headphones to produce said frequencies.
Someone correct me if I am wrong. Thanks. |

oops, missed the entire concept i guess. That's pretty cool
now i'm going to crack open soundforge and myself up
But I still stick to what I said about unheard low frequencies, besides these "binaural" signals. |
