What determines whether a sound is perceived as noise or something pleasant is often how much control you have over the experience. Compare it to music that you can play, turn up, turn down, and turn off yourself, and music that someone you don't know is playing right next to you.

How the sound environment affects our experience
How we experience a sound environment is strongly linked to our well-being. But since the actual experience is individual, it is important to understand the factors that can influence different people's impressions of the whole.
The sound environment around us is neither constant nor something that can be isolated. Instead, it is created in interaction with both the room and other people, where those experiencing the sound environment also contribute to shaping the experience. Yes, as you can see, it quickly becomes quite abstract. Therefore, let us now take a look at some of the details regarding the sound environment and experience.

How we understand and interpret the world
Our understanding of a sound environment is also based on our previous experiences. We use that knowledge to predict which sounds are likely to appear in a particular context, but also to filter out interpretations that do not match the place we are in.
However, when what we see and hear do not align, it becomes more difficult to interpret a situation, which means that our energy and attention are spent trying to identify what is not right.

The impact we carry with us
The things we have mentioned so far mean that two people can be in the same sound environment but not hear or interpret it in the same way at all. Perhaps they focus on different sound sources, perhaps they have different pre-understandings and prior experiences of the sounds in the sound environment. And perhaps they are engaged in completely different activities that affect their experience.
At the same time, there's a sort of feedback loop where we are not only influenced by the sound environment but also make our own impact on it through our actions.
We've probably all been annoyed by people who we feel take up too much space in our shared sound space. An interesting experiment is to think about how much sound we ourselves make in different contexts, such as when talking on the phone at work, walking around, or opening and closing doors. It can be quite surprising to discover how much noise we contribute without being aware of it.
And the behaviour of ourselves and our colleagues is, in turn, influenced by both individual personality traits and the workplace culture we are in.
We must not forget how much influence our emotions have on the experience. If we have a positive attitude towards a place and its context, we are more likely to have a positive attitude towards the sound environment of the place and its context as a whole.

Emotions and characteristics
If we understand the meaning of a sound and also consider the source of the sound to be useful or meaningful, we tend to like that sound better. Simply put: sounds that originate from things we like are perceived as more positive.
Of course, the characteristics of the sound also play a role. Sudden and occasional sounds create an immediate reaction in us, compared to constant and slow sounds. And a reaction means a distraction.
Considerations
To summarise, the experience of a sound environment depends on a variety of factors, not least that it is individual what can be considered a good sound environment. Therefore, it is not enough to just rely on building requirements and sound classifications when creating the foundation for a sound environment.
What we want to convey with this article is: Think instead about what will affect how the business is conducted in the premises. What will influence the social environment created there? How can the sound environment be adapted to the employees' activities and individual needs?
And how can the interior design and the visual design of the premises enhance the connection between the activities, the needs, and the sound environment?
