Looking for a light that strobe at 40 hertz : r/light - Reddit

Electrical and chemical outputs are modifying lots and lots of biological programs.Andrew Huberman:Is there an actionable tool related to these studies yet? Well, that sort of depends on how adventurous you are. Right now, these studies are being explored in the context of clinical trials in people with Alzheimer's, dementia and other forms of neurodegeneration. Is it dangerous to look at a 40-hertz flickering light? Well, in general, the answer is going to be no. However, if you're prone to epilepsy, for instance, staring at a flickering light of a given continuous frequency can induce seizure, right? That might surprise some of you, but it shouldn't because as this study illustrates, and as anyone who's ever been out at night to a club or something illustrates, when you look at a strobe light, for instance, your whole world of visual perception changes, but actually the rhythm at which you perceive music, at which you perceive conversation, at which you perceive the movement of your body actually changes according to the patterns of visual flicker. In most cases, strobe, if we're using the sort of club dancing example, your brain is entraining to its outside environment.Andrew Huberman:So given the power of flickering lights to entrain brain rhythms, I think at this stage it's probably too preliminary to really suggest a specific protocol, but I would definitely keep an eye out for these sorts of studies. They are coming out all the time, and I think in a very short period, we are going to see specific protocols that one could potentially use even at home, and, of course, these are noninvasive protocols in order to place the brain into a particular state, not just for sake of offsetting neurodegeneration, but also for enhancing focus, for enhancing the transition into sleep and other brain states as well.Andrew Huberman:Today, I covered what I would say is a lot of information. My goal was to give you an understanding of how light can be used to change the activities of cells, organelles within those cells, entire organs, and how that can happen locally and systemically. We talked about the power of light to impact our biology at the endocrine level, neuronal level, immune level, mood, et cetera through both illumination of the eyes, and the skin and other tissues as well.Andrew Huberman:I realized that even though this was a lot of information, there are many aspects of phototherapy that I did not cover. I know there's a lot of interest nowadays, for instance, in the use of red light and other wavelength light therapies for ovarian health and testicular health. In fact, I get a lot of questions such as, "Can red light be Piano Tuner is a 12-note chromatic scale strobe tuner and partial analyzer application that utilizes audio input devices such as built-in microphone, line-in, and iSight. Strobe tuners are extremely accurate compare to regular tuners with a needle or LEDs. The slightest difference between the actual pitch and the ideal pitch accumulates over time and appears as a movement on the strobe tuning meter. Piano Tuner can be used by someone who wants to learn how to tune a piano by using a tuning lever and also be used by a professional piano tuner to help the tuning process. You can now use the Partials window to figure out the cent offsets of the stretch table for your piano, or you can use the Partials window alone to tune your piano directly without a stretch table. NOTE: A piano requires tuning, voicing, and regulation at least once a year by a professional piano tuner in order to keep it in a good condition. Tuning: 12-note chromatic scale. Temperaments: Customizable (±50 cents). Supports Scala scale (.scl) files. Stretches: Customizable (±50 cents). Meters: Strobe, cent, and hertz. Range: 9 octaves. C0 (16.352Hz) - B8 (7902.133Hz). Accuracy: ±0.1 cent with the cent readout. ±0.1 cent @ 440Hz with the strobe tuning meter. Calibration: 349.000 - 499.999Hz (0.001Hz steps). Display: Resizable 88-key piano keyboard. Sound Back: Plays the reference tone (sine, triangle, sawtooth, or square wave) at the ideal pitch. Hilbert Scope: Visualizes harmonics impurity. Partials: Displays the cent offset of each partial. Speech: Speaks the current tuning status and the partials analysis information. Instructions: Please refer to the manual in the disk image. Click here to find out how to tune a piano yourself.

Solved What is the frequency, in Hertz, of a strobe light - Chegg

We've been talking about up until now involved constant illumination with a given wavelength. Here, it is wavelength generating patterns of illumination. Light on, light off, light on, light off, at a particular frequency. So what they found, for instance, using this pattern of stimulation — and by the way, the stimulation was called genus gamma entrainment using sensory stimulation; so G-E-N-U-S gamma entrainment using sensory stimulation — had a number of really interesting effects.Andrew Huberman:First of all, it reduced so-called amyloid plaques and phosphorylated tau, amyloid plaques and phosphorylated tau are associated with Alzheimer's and normal age-related cognitive decline. So this is incredible, right? A pattern of flashing light delivered to the eyes creates a pattern of neuronal firing, not just in the visual areas of the brain, but in other areas of the brain as well, that in turn, trigger molecular pathways that reduce some of the markers and the cause of age-related cognitive decline in Alzheimer's.Andrew Huberman:And in parallel to that, they observed an upregulation of some of the biological pathways that lead to enhancement of neuronal function, maintenance of synapses, which are the connections between neurons, and so on and so on. They have discovered and list out a huge number of these biological effects, both the reduction in bad things, so to speak, and the improvement in good biological pathways. And I find these studies so exciting because first of all, they're noninvasive, right? There's no drilling through the skull. They are very tractable in the experimental sense, meaning that you could imagine that if 40-hertz stimulation turns out to be the very best stimulation protocol to induce these gamma oscillations, well great, but because it's noninvasive, it's fairly easy to explore 50-hertz stimulation, 100-hertz stimulation, 20-hertz stimulation, and to do that with different wavelengths of light.Andrew Huberman:And so, that's what's happening now. The CyLab and other labs are really starting to explore the full range of variables that can impact oscillations within the brain and their downstream consequences. So again, this is phototherapy, but phototherapy of a very different sort that we've been talking about up until now. It's phototherapy designed to trigger activation of biological pathways far away from the very tissue that's being illuminated. And it calls to mind the same sorts of mechanisms that we were talking about earlier, where illumination of the skin with UVB light is setting off an enormous number of different cascades in different organs and tissues, including the spleen, the testes, the ovaries, and so on. So again, light has these powerful effects both locally on the cells that the light is delivered to, but also systemically in terms of the cells that are changing their.

What is a Tuner?A tuner is a device musicians use to detect pitch accuracy. It will let a musician know if the note they are playing is sharp (too high), flat (too low), or if it is in tune. The accuracy of a pitch is what musicians call intonation. Tuners work by detecting the frequency of the pitch (sound waves). For example, an A is 440 Hz. If an A is sharp, it will be 441 Hz or higher. If it is flat, it will register as 439 Hz or lower. While tuners work by tracking hertz, musicians measure how close they are to the pitch in measurements of cents. Cents and hertz are not the same things. How To Use A Chromatic Tuner?Playing with a tuner will help develop your intonation and an understanding of the tendencies of your instrument. To use this instrument tuner, make sure the built-in microphone has web access. Play any note. You will see the needle move and the strobe rotates until it finds the pitch you are playing. This tuner is tuned to A440. Remember, these notes are shown in concert pitch. If you play guitar, piano, or another instrument pitched in C, then you will see the note name of the pitch you play. If you play an instrument that needs to transpose, like a trumpet or French horn, then you will need to understand how to transpose.Once the tuner recognizes what note you are playing, try to adjust it so that it stays perfectly steady and centered on the dial. If you had to bring the pitch up, you were flat. If you had to bring the pitch down, then you were sharp.Make an adjustment to your instrument, either by adjusting a slide, a peg, or whatever your instrument's equivalent is. Play the note again. If the needle and strobe are centered and steady, then your instrument is tuned.Granting Microphone AccessThis tuner will require mic access through your web browser. If you have disabled it in the past, then the tuner will not work. - Chrome: Go to Settings -> Site Settings -> Microphone and allow this site to access the microphone. - Firefox: Go to Preferences -> click Privacy & Security -> Scroll down to permissions and select Settings. Search this site and select Allow.- Safari: Safari > Preferences, then click Websites.

Of light, but wavelengths of electrical activity in the brain that can be restorative for certain aspects of learning and memory, and can actually help create molecular changes in neurons that lead to clearance of debris and even reductions in age-related cognitive decline. So, the way to think about brain waves and brain oscillations is that neurons are electrically active; that involves chemicals, et cetera; and they can be active in very slow, big wave forms. So you can think of delta waves, meaning, so you can imagine a wave of electrical activity that comes along very infrequently. So a given neuron fires, and then some period of time later, fires, and then some period of time, even later, fires. Or you can imagine that that same cell is very active; fires, fires, fires, fires, fires. You can imagine if it's firing very often, it's going to be short wavelength, right? Shorter gaps between firing, or if it's firing very seldom, you're going to think about that as longer wavelength firing.Andrew Huberman:Turns out that gamma waves are one pattern of firing that lead to downstream metabolic functions and biological functions that end up clearing away debris that's associated with aging in cells. And that also lead to molecular changes that enhance the kind of youthfulness of neurons, so to speak. How do we induce gamma oscillations within the brain? Well, what Li-Huei Tsai and colleagues have beautifully shown is that by delivering certain patterns of light flicker, so lights going on and off at a particular frequency, the brain as a whole starts to entrain, meaning it matches to those particular patterns of light flicker, even though many of the brain areas that do this are not directly within the visual system or visual pathway.Andrew Huberman:So the studies that I'm referred to are several, but the one that I'd like to highlight is entitled "Gamma entrainment binds higher-order brain regions and offers neuroprotection." What they essentially did was to expose subjects to 40 hertz, which is a particular frequency of illumination to the eyes. So it's light goes on, light goes off, light goes on, light goes off, at a frequency of 40 hertz. And when they did that and they recorded the activity of neurons within the brain, not just within the visual areas of the brain, but within other areas as well, they observed increased gamma oscillations, meaning that the electrical activity of the brain at large started to match to the patterns of light that were delivered to the eyes.Andrew Huberman:This is really exciting and very unique from the different types of phototherapies that we've been talking about up until now. All the patterns of phototherapy that
