NOISE CANCELLING MAGIC https://www.youtube.com/watch?v=YNK4Wc3-Ij4 (Noise Cancelling Heaphones Experiment)

BACKGROUND

"세상에 혼자 있는 기분"이라거나 "우주 공간으로 날아간 기분" -> Feel like I am alone in this world / Feels like over the moon-in the space Review of Noise cancelling headphones

In Seoul, the city is super noisy and very crowded. You are constantly surrounded by all the mass/mess. So by having a noise-cancelling headphone, it allows you to make a personal space. Having a personal space was not a key concept in conventional history. For example, the door knob/ door is a very Western concept. By closing a door meaning having a private space.

private space as privilege -> maybe even the most privileged ppl in back in the days, did not have personal spaces... idk(need more research)

I think this shows the recent tendency of ppl feeling tired of life, constantly surrounded by unwanted stimuli.

"How people are using noise cancelling to settle in the silence and revel in the sounds." Real stories of people tuning in or out to feel peace, find escape, and for self-care.

how can we distinguish the material functioning from the ideological functioning? see also "perfomative materiality and theoretical approach to interfaces" by Johanna Drucker

ANC(Active Noise Control): Active noise control (ANC), also known as noise cancellation (NC), or active noise reduction (ANR), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first. The concept was first developed in the late 1930s; later developmental work that began in the 1950s eventually resulted in commercial airline headsets with the technology becoming available in the late 1980s. The technology is also used in road vehicle and in mobile telephones.

noise-cancelling headphones: Noise-cancelling headphones are headphones that reduce unwanted ambient sounds using active noise control. This is distinct from passive headphones which, if they reduce ambient sounds at all, use techniques such as soundproofing. (wiki)

how does it work? A microphone captures the targeted ambient sounds, and a small amplifier generates sound waves that are exactly out of phase with the undesired sounds. When the sound pressure of the noise wave is high, the cancelling wave is low (and vice versa). The opposite sound waves collide and are eliminated or "cancelled". (wiki) what are the premises for its functioning and for its development?

the noise reduction probably started from the desire to record sound to achieve the most accurate copy of the “original”.

"Throughout the history of sound reproduction, efforts to prevent, reduce, or eliminate all of the noise and distortion produced by sound media were a major concern for inventors, engineers, and developers; and the myth of perfect fidelity, based on the ideal of the vanishing mediator, retained a strong appeal. From the standpoint of noise reduction practices, noise and distortion are inherently negative and disruptive. As the conceptual genealogy provided in the previous chapter makes clear, however, the fight against noise and distortion ultimately amounts to an interminable game of cat and mouse. First come innovations in sound definition. It then emerges, however, that the new technologies affect the sounds they reproduce, often in unforeseen ways, which in turn demand new measures for preventing, reducing, or otherwise eliminating these effects." ---------> at some point when engineers try to clean a certain sound from the noise they end up altering the sound. Because 🤯 noise is fundamental to the sound. 🤯

"Everyone who is serious about music should buy a pair of noise cancelling headphones. You may be an audiophile, or you may be someone who doesn't want to think too much about your headphones. Either way, noise cancelling headphones are purpose-built for destroying outside noise, and they're really good at it." soundguys.com

it relies on 1 the idea that the high fidelity reproduction of music (or every cultural object) is something always desirable. 2 that a cultural object is detached from the world where it comes from. 3 that contamination between the piece and the soundscape is something that impoverish and not enrich it.

this is great!! sorry for intervening

- an object for a single user fruition - and by removing significative manifestation of the world it enforces a concept of individuality - its functioning supposes a center and a rest of the world (well, 👂 two centers 👂) - it reminds me about the visual critics about linear perspective and how occidental visual culture is embedded with anthropocentric premises.

- this devices make no distinction between sound and noise, in fact it treat everything as noise,

- ideology and narratives: it's difficult to think about ideology without casting new ideologies on things ? i mean it's always a matter of encoding / decoding signs: re enchanting objects with our ideologies

what does it cancel? it cancels the lower frequencies for cutting specific sound that are perceived as noise. but...

it's an objects that makes self-isolation not only possible but also desirable:

   - how  does it materially work? it registers the frequencies of the surroundings and reproduces them but inverted, so to neutralize the formers
   - what does imply?

+ that there is a noisy background + that this noisy background is to be rejected for various reason in various occasions (to improve attention/concentration, to filter too many inputs, to ... etc) + that you don't have power on silencing your surrounding by interacting directly with it (passively)

to certain extent the noise cancelling headphones make me thing of false consciousness the most, because it seems super normal to use them in very chaotic environments as they offer a very quick and normalized solution. at the same time they are an object that could turn out handy in situations where an high performance is required. I'm thinking about the optimization of productivity, but also the example of the guy in the spectrum of autism whose well-being is not sought by intervening on the cause of extra-inputs but on the immediate-temporary filtering of those. yes, in the end, i think the point of this device is that its design, development and functioning are soaked of a certain ideology to the extent that by not intervening directly on the causes of noise while filtering noise for a person, it can be repurposed in a world in which the responsibilities for solving a problem are dropped on the individuals, that the solving of this problem is temporary, but that this temporary solution is normal and preferable because the environment is immutable.

+ they might be used in open offices where employees work really close the one to the other in order to reduce the sound and be more productive. + machines as computers, fridges or other people working may produce low frequency sound, that is perceived as noise and then it is cut out. But why exactly are they cut out? + in several contexts the female sound frequencies have been perceived as noise. So another important question is what range of frequencies is perceived as noise from the designer of a product and what is the filtering of this noise.
