Room 1
Room 1 is a small bedroom located next to the kitchen on the first floor. Although the room itself is relatively quiet, it receives sounds from several surrounding sources. The most noticeable sounds are kitchen activities, such as cooking, dishes, and movement, which are transmitted through the adjacent wall. Airplane noise can also be heard from outside, especially when aircraft pass overhead. In addition, occasional sounds from other parts of the house, such as voices and footsteps, can enter the room through the corridor.
Because of its small size and enclosed condition, sounds inside Room 1 feel relatively direct and close. External sounds are usually quieter and more muffled, while nearby sounds from the kitchen are more clearly perceived. The room therefore has a layered soundscape, combining low-level outdoor noise with more immediate domestic sounds from the adjacent spaces.

Room 2
Room 2 is located closer to the circulation area and is therefore exposed to a wider range of sounds from different parts of the house. Sounds from roommates talking can be heard from the nearby corridor and shared spaces. Toilet flushing and showering noises are also noticeable because the bathroom is located close to the room. From the upper floor, television sounds and footsteps on the stairs are occasionally transmitted downward. In addition, construction noise from outside can enter the space and become part of the background soundscape.
Compared with Room 1, Room 2 has a more active and variable acoustic environment. Some sounds, such as conversation and footsteps, are intermittent, while construction noise may continue for a longer period. The mixture of indoor domestic sounds and outdoor construction noise makes the space feel more acoustically exposed and dynamic.
