Music from Ventilators - Part 2: ASMR and the Colours of Noise.

Note: for better understanding, please read Part 1 of this article 👉first.

If you are reading this, you may have come across the term ASMR before. ASMR (Autonomous Sensory Meridian Response) is a relatively new definition and means something like "sensory massage" or "brain orgasm". ASMR is used as an acronym in the German-speaking world; there is no official corresponding German translation for the term. ¹

However, it can be described quite well: For some people, hearing certain sounds and other auditory stimuli causes a tingling sensation on the skin that spreads from the head down the spine to the buttocks. This sensation is often described like a pleasant shiver of goose bumps, but it lasts longer and is more intense. Triggers for this include whispering, speaking or singing softly, or the sound of touching an object with long fingernails. After all, this type of ASMR video has already made it to several million videos and millions of enthusiastic subscribers on Youtube.

For many, ASMR seems to be strongly associated with this type of Youtube video - although the phenomenon has been around much longer than Youtube has even existed. A very important figure in the 1980ies was painter Bob Ross, whose quiet speech and soft brushing gave some viewers their first "ASMRgasm".

Personally, I am a devotee of a variant of ASMR that has to do exclusively with "white noise." My brain massage starts automatically when I catch a fan somewhere, a ventilator, a heater. If it's also raining and thundering and lightning, i am practically in heaven. The fact that you feel a sense of happiness when you feel a warm stream of air may well have its origins in early childhood experiences of security. Many people, for example, also love the sound and warm blast of a hair dryer - and can be incredibly creative from this state.

Analog fans and hair dryers are of course the real thing - but the constant use of these devices is of course also a question of cost. It's cheaper to switch back to videos. On Youtube there is white noise in all combinations for really every need: rain, rain with thunder, rain with thunder and fan heaters, all kinds of fans, sounds of server rooms, sounds of trains, airplanes, even all kinds of agricultural machinery noises - the possibilities are endless. Here you can choose what makes you feel good, depending on your intuition. But you can also do a bit of analysis beforehand - by taking a closer look at the "basic material", i.e. the noise.

>> For this, we will leave out all the physical definitions - there is an analogy that illustrates the whole spectrum of noise quite well, namely that of light: Just as white light contains all colors, white noise contains all frequency spectra - including the high frequencies. We know this noise from earlier times, when there was NO program on TV and the well-known "snow flurry" on the screen was accompanied by a loud noise. If you filter out certain frequencies from the white noise, you get different frequency spectra that are perceived as stressful or pleasant, depending on your personal disposition - and these are designated with different colors.

Pink Noise: Pink noise has been the most popular frequency spectrum for a number of years: white noise is joined here by a relatively concise bass sound that softens the high, "sibilant" peaks. Rain is a perfect example of pink noise; because of its soothing, unobtrusive sound, pink noise is therefore also often recommended for calming crying babies, but also for people with problems falling asleep and, on the other hand, for students to promote concentration.²

Brown Noise: Brown Noise has even less treble components, whereby here the low and middle frequencies are approximately equally intense. By the way, in the technical literature "Brown" is not a color classification, but comes from "Brownian Motion", named after a specific way in which particles move in a liquid. Brown noise is most reminiscent of strong wind or the sound of large ocean waves crashing in. 

Blue Noise: Blue noise is mentioned here only for the sake of completeness; it contains only high frequency components. This spectrum is used in recording studios, for example, to round off any overmodulation peaks in a recorded song afterwards.

Gray noise: This is the spectrum your blog host is most comfortable with; it mainly uses low frequencies. This is the sound of huge fans used in industry. Musically, Grey Noise is essential for the composition of so-called drones. 

Green Noise: Due to its mainly mid-frequency components, Green Noise is often used to simulate ambient sounds in nature.

By the way, a purely theoretical concept is "Black Noise": The absence of all signals would mean total silence - something that is nowhere possible on earth (I wrote about it in the first article of this series). 

So with this rough classification, it should be possible for the curious listener to find the perfect noise for them. What you do with it (mask the tinnitus, fall asleep easier, concentrate better, etc.) is up to you. For the pareidolia described in the previous article, which can trigger quite exciting audio phenomena such as voices and "ghostly" music, I recommend a combination of different sounds and for sensation enhancement the consumption of various substances.
