It sounds like someone by chance hit adjoining keys on a xylophone. The understated double ping hits me with a jolt of pleasure, a swooping stomach, and even a bit of aid.
Each time I hear the now-retired Facebook Messenger notification, I’m transported back to 2013, when I happily, gratefully, giddily acquired a message from someone I appreciated, who would later grow to be my companion. Back then, we talked virtually day by day on, of all chat platforms, Messenger.
As units, software purposes, and apps grow to be omnipresent, the Consumer Interface (UI) sounds they emit — the pings, bings, and blongs vying for our consideration — have additionally started to contribute to the sonic material of our lives. And just as a track has the facility to take you back to a specific second in time, the sounds emitted by our related units can trigger reminiscences, thoughts, and emotions, too.
“The sounds that we have are adding to that tapestry,” Will Littlejohn, Facebook’s sound design director, stated.
Should you’ve had a very worrying job with a trigger-happy boss, maybe you are feeling a churn of hysteria when a notification tells you you’ve acquired an e mail. Or in the event you grew up a toddler of AOL, perhaps an intense, vivid memory of utilizing AIM as a tween happens if somebody performs you the long-lasting doorways opening and shutting sounds. When distinct and repeated sensory stimuli, like UI sounds, are paired with feelings, moods, and reminiscences, our brains construct bridges between the 2.
“Who we are is not just the neurons we have,” Santiago Jaramillo, a University of Oregon neuroscientist who studies sound and the brain, stated, referring to cells that transmit info. “It’s how they are connected.”
My associate and I started our informal courtship in 2013. For the subsequent yr, as we flirted, chatted, and have become increasingly part of each other’s lives, our most popular mode of communication was … Fb Messenger.
Fb was already considerably uncool by then — the times of painstaking album uploads had pale — but as young 20-somethings trying to chat in the course of the day about nothing a lot, it labored for us. By some means, texting felt too formal. But we weren’t on the level of chatting every day over Gchat, like we both did with our associates. We have been buddies on Facebook, and Messenger was a method we might keep in constant communication, with out the dedication or overt familiarity of different platforms.
In the intervening years, I didn’t use Facebook Messenger much. But when I did, and when I acquired a sound notification when I wasn’t expecting it, I observed that the sound would immediately make me consider my associate. I might even get a sweep of aid and excited nervousness, like the individual I used to be in had just despatched me a message to say “hi,” confirming that they favored me with a DM, yet again.
Once I explained what happened with the Facebook Messenger sound, Jaramillo responded with amusing: “You have been conditioned.”
Pathways to the past
For the last 30 years, scientists have been utilizing animals, like mice, to find out how sound becomes related to a memory, thought, feeling, or state of being. They’ve discovered that your brain creates pathways connecting the elements that process sound with the elements linked to emotions and reminiscences.
When your brain registers some kind of stimulus, like a sound, you’ll be able to process it in quite a lot of methods. You may need an innate response, resembling jumping when you hear a loud sound. You may also glean info from the sound: For example, the sound of an idling engine tells you somebody is waiting outdoors.
In probably the most primary experiments that illustrate this, researchers shock a mouse each time it hears a specific sound. After a certain period of time, simply listening to the sound — without the shock — causes the mouse to leap as if it had simply been shocked. What I used to be experiencing when I felt my own jolt of excitement at the Facebook Messenger sound was a more complicated model of this similar phenomenon, Jaramillo explained.
“It is through these changes and connections in the brain that you associate these sounds with these responses,” Jaramillo stated.
Within the brain, a sound isn’t just the uncooked knowledge of a sound wave: there’s all the time one thing extra to it. In response to a research Jaramillo revealed in January, we associate sounds with reminiscences on the first pitstop sound makes in our brains: the auditory cortex. Because it gets digested in extra complicated areas of the brain, these associations only grow stronger.
This could have a domino impact all through the brain, prompting powerful feelings.
“It’s almost like a multiple step process,” Jaramillo stated. “Once you bring an association, that brings with it many other associations.”
I questioned why the Fb Messenger sound prompted this reaction in me, while different sounds — like the Gchat notification sound — had no specific emotional effect. The Gchat sound continues to be coded with info (it’s telling me I’ve received a chat!) — but that info isn’t powerfully related to a memory or feeling.
It seems my associate and I had inadvertently created the right circumstances for creating a robust neural pathway.
“To be effective for creating associations, a sound has to be clearly differentiable,” Jaramillo stated. “Then, if you have consistency and repetition, a strong association will be created.”
The Fb Messenger sound hit all of those standards. It was a singular sound, that was persistently associated with a selected experience, repeated many occasions. Because I solely ever actually talked to my companion (and never other individuals) on Fb Messenger, I related the sound with him; as a result of we talked lots, the association turned robust; because we repeated the experience virtually day by day for a few yr, it turned engrained — so engrained that years after the very fact, an sudden encounter with the sound rendered the emotional memory as if it have been occurring another time.
“There are experiments where you don’t present a sound for a long, long time,” Jaramillo stated. “But if you present it years later, you may still recall the memories. Some of the neurons keep those memories. Some of those seem to be very powerful in how long they last, and researchers are still trying to understand what are the mechanisms that allow you to have such a long, long memory.”
Designing for all times
Earlier than notifications turned a continuing a part of our lives, sound designers did not take as a lot care in their creation. Consider the grating early Nokia cellphone ring, or how annoying the AIM door shutting and opening might turn out to be if a pal acquired signed on or offline each time their pc went to sleep or awoke.
Right now, sound designers are wiser, and extra thoughtful, about how the sounds they design might be both helpful, and — the holy grail of sound design — unnoticeable. A whole lot of that mission has to do with considering by way of what emotions the sounds themselves may evoke.
“The best sound designers are not going to talk about the tools or the tech, they’re going to try to pull emotions out of people,” Dallas Taylor, a sound designer who runs a well-liked podcast about sound, referred to as Twenty Thousand Hertz, stated.
These emotional issues are something that sound designers contemplate on the highest levels.
When Littlejohn, Facebook’s head of sound design, and his workforce design the sounds that populate Facebook, they attempt to create a sonic id for the platform, while additionally presenting a impartial canvas.
“From the very beginning when we’re crafting sounds, we’re making sure that the sounds are designed in such a way that they will not create negative emotions over time,” Littlejohn stated. “We’re not trying to create sounds that are creating positive associations overtly, what we’re trying to do is create sounds that have the potential to create great associations, if that’s the context in which they’re heard.”
In different words, the sounds themselves don’t create the feelings – the associations do. But the typically repeated nature of UI sounds, and the social context in which they’re used, makes them ripe for emotional connections.
“The sound itself can’t force a feeling,” Taylor stated. “It has to be the context that that sound is in.”
Moreover, UI sounds themselves could also be new — and specifically primed for affiliation – however the phenomenon is just an extension of how our brains already process sound, whether created by the wind and the timber, or a buzz in our pocket.
“These cues are what help to bring context to what we’re experiencing with our other senses,” Littlejohn stated. “That’s how we interact with the world. Whether it’s being created through a device, and we design what’s emitted, or whether it comes from nature or something mechanical, I think that relationship has always been there. It’s now manifested in a new way through technology.”
A leaking time capsule
Buried in an episode on UI sound design on Taylor’s podcast was the Fb notification noise that soundtracked the primary six to 12 months of my relationship. In contrast to the new, high-pitched, cheery “pop ding” notification, this one, which was used by Fb previous to 2014, is extra musical, yet muted. Once I heard it, I knew immediately that this was the true retailer of my emotional reminiscences about those early flirtations.
Beginning in 2013, I heard the clumsy xylophone — whereas for latter day chats, the pop ding. And I have a deeper connection to the primary one. Unbeknownst to me, the memory had been mummified in my brain, ready to be re-awoken by the podcast.
“The memory is kind of there in the brain, latent and hidden,” Jaramillo stated. “If it gets associated again with the particular event, then it would reappear.”

In fact, the flip aspect of my sonic revelation is that the reminiscences and feelings associated with the post-2014 sound have gotten diluted. I just lately started utilizing Messenger extra to communicate with a gaggle of colleagues. The butterflies in my stomach don’t flutter as arduous when I hear the pop ding today. However they still do when I hear the classic notes.
“When you hear the same sound, but you don’t get exposed to the same thing, then the association can fade,” Jaramillo stated.
Because of a technological coincidence, I’ve a nostalgic jewel contained within a sound I’m unlikely to hear, until I search it out. That’s especially powerful for me at this time, six years later. However I can’t go back to it on a regular basis, or the association will develop into weaker.
However I don’t have to, anyway; as my associate and I create new sonic associations I’ll uncover in another six, 16, or 60 years that those first six months are nonetheless encased in neural amber. And that’s sufficient to make my stomach flip every time I select to consider it.
