Sound is one of the mediums that connects everything. In most cases, people communicate with each other through sound, establish connections with their environment through sound, and even different environments can be connected through sound. But when language is no longer the medium, what does it sound like when you are in this environment?

A study conducted at the Brain & Mind Research Institute has revealed a close relationship between social anxiety and decreased heart rate variability (HRV). HRV refers to the variations in successive heartbeat intervals or, in simpler terms, the fluctuations in heart rate. It is determined by the differences in duration between two consecutive R-R intervals, which represent the tiny variances between one heartbeat and the next. If the intervals between two heartbeats are relatively consistent, HRV is lower, whereas if there is greater variability in the intervals, HRV is higher.

Apart from language, what sounds can people make to express their physical or mental states?

What are the ways to create a genuine emotional expression environment in communication that goes beyond social etiquette, enabling people to better understand the emotions within themselves?

How can we facilitate the understanding and acknowledgment of the authentic emotions and reactions of individuals with social disorders or autism, and how can we assist them in finding a more suitable place and recognition in society?

In an ideal scenario, the entire installation would be covered with a layer of mirrored paper and a lenticular sheet on the outside. This way, when other visitors in the exhibition space view the artwork and a specific observer experiences it inside the box, they would not be able to see the experimenter's head. Such a design implies the status and condition of individuals with autism and social anxiety disorder in society – they are among the most easily overlooked groups.

Due to space constraints, the ideal hanging setup had to be substituted with stands. This provides additional design flexibility on the stands.

The mechanism for triggering sound by the sensor is as follows: The sensor detects the person's heartbeat, calculates Heart Rate Variability (HRV) through Arduino, and then converts the HRV value into MIDI values within a certain range.

This means that:

The bigger the fluctuation in heartbeats = the more dynamic the musical notes = bigger variations in melody = more relaxed and appreciation state of mind.

Smaller fluctuations in heartbeats, or regular patterned fluctuations = relatively less dynamic musical notes =more frustration state of mind.

Initial concept: I want to create an effect using a lenticular sheet where, when viewed from the outside, the audience's heads appear invisible.

# data[].attributes.body
However, due to the limitations of the lenticular sheet's effect, I have decided to create a stark contrast in colors both inside and outside the installation.

The exterior will be pure white, while the interior will be pure black, with the surface of the installation covered by a white fabric and plastic sheet. This represents the idea that individuals suffering from social anxiety disorder are often difficult to notice in society, and their inner voices are frequently trapped in a dark world.

The sound triggered by the sensor resembles the sound of murky raindrops. The choice of this sound source is not only based on its aesthetic appeal but also in combination with the large reverberant space environment of Dilston Gallery. This setup aims to create an experience where the participant can only hear the space but cannot be seen by others in the space, and likewise, the participant cannot see the feelings of other spectators.

The second source of sound is a continuous real-time recording of the pavilion, allowing the audience to hear the environment they are in.

The third sound source is some field recordings of natural environments. The sounds of the natural environments are blended with the sounds of the human society in the field, provoking people to think about the different states of "I" in different environments.

Our heart beat is not regular like the ticking of clock beating once every second. A healthy heart beat is irregular. This irregularity is desirable and an indicator of how ready the body is to adapt to stress. This stress could be bad like a fight with your boss or good like a promotion. When HRV is high, you can handle the incoming stress. When HRV is low you are less adaptable and less able to handle the stress.

HRV can be a measure of our autonomic nervous system and the balance between our parasympathetic and sympathetic branches. The parasympathetic branch is our “Rest & Digest” and correlates with a high HRV. The sympathetic branch is our “Fight or Flight” and correlates with a low HRV.
