ROOM 1 :

Cellar/basement/laundry room of an apartment building.

This space is the communal basement and cellar for the entire building (10 apartments). It is on the -1 floor, underground. It is composed of different small-sized “rooms”, all adding up to around 25 sqm.

Ambient sound in the entrance

The entrance of the space feels like it should be echoey, but it is not. There is a continuous background noise from the washing machine and dryer, creating a sort of dead and boomy atmosphere. Every sound becomes a bit muddy, toned down from the materials of the space, but also the humming from the machines and the heater. It seems almost cavernous, and being underground with no connection to the outside reinforces this feeling.

These two “rooms” are quite similar in atmosphere. Very boomy and boxy, the sound does not echo, and everything feels absorbed. You can still hear and understand the size of the room, you can also hear how far you are from the laundry room and how many walls separate you from it.

And finally, the laundry room. You can hear it the second you step out of the elevator (when the machines are turning). It is loud, dense, with a lot of different sounds and frequencies all merging. There is this constant whirring, mixed with the clanging and rattling of the metal from the machines and the splashing coming from the pipes. It is also very hot in the room, making it rapidly overstimulating.

ASSIGNMENT 3 :

5 claps in the corridor – basement

Analysis of a clap :

Found a delay of 0.09 s for 30 dB, so a total delay of (0.09 * 2) = 0,18 s

By putting the measurements in a calculator, with a RT Goal of 0.2s :


ROOM 2 :

Elevator

This space is way simpler than the basement, but I felt it was interesting to compare the two and to understand the full auditory experience of going to the basement.

This elevator is about 1.5 sqm, all made out of metal, except for the floor, which is made out of a sort of resin.

The sound here feels metallic, almost robotic. When the elevator does not move, the ambience is dead, boxy, and a bit sharp in some ways. There is not much echo, the sound is clear and the room feels small.

When the elevator is moving, the ambient sounds of metal clanging, thumping from the doors and whirring of the motor, cover the voice quite easily. On top of this, there is the voice annoucement and dings that emphasizes this robotic atmosphere.

Overall, the auditory experience of going down to the basement is quite dense, with mostly low frequencies, thumping and rattling.
