Room: G01 - IT cluster
Date: 27/04/18
Period: 16:43-17:27
Duration: 44min
Weather condition: Light rain
Equipment: NTi Audio XL2 Sound Level Meter
Occupation level: Moderate
NR: 54 (Guide A 35-45)

LCeq: 60.0dB (Guide A 65-75)
A computer cluster able to accomadate up to 14 students. Acoustic levels are low in the lower frequency spectrum but rise above guidelines for the higher range. Outdoor noise is not an issue thanks to the secondary glazing of the two windows. Noise mainly comes from the reception corridor when the door to the cluster is open. Annoying sources of noise include the slamming of the door and constant tapping on the computer keyboards.
Room: 202 - Open plan office
Date: 27/04/18
Period: 9:58-10:48

LCeq: 58.1dB (Guide A 60)
An open-plan office for PhD. Two windows facing the courtyard. Raining and windows open during the measurement. Better acoustic performance at lower frequency level. Main sources of noise consist of computer cases, keyboard typing, mouse clicking, occasional people talking in the neighbour seminar room, and the noise from the outside (rain, traffic). Overall noise level higher than the guideline values while the user satisfaction level is still relatively high.
Room: 328 - Small office
Date: 27/04/18
Period: 13:53-14:01
Duration: 8min
Weather condition: Broken clouds
Equipment: NTi Audio XL2 Sound Level Meter

LAFmin: 48.2dB
LAeq: 51.5dB (Guide A 35)
LCeq: 68.8dB (Guide A 60)
The office in room 328 is occupied by 3 people. Acoustically, the internal environment is very good for working. It looks onto the quiet courtyard, so is minimally affected by the outdoors and the ambient noise levels are so close to white noise that they do not cause distraction. Due to the minimal amount of people in the room, noises made by the occupants are unlikely to be problematic.

An office occupied by 7 people. Only one person present in the room during the measurement. Two windows facing the courtyard. Main sources of noise consist of computers, printing machines, keyboard typing, mouse clicking, occasional people talking in corridor, and noise from the outside traffic. Overall noise level is slightly higher than guideline values.

B01 is well insulated, therefore isolating it from the atrium and the main road on either side of the room. Background noise levels are low, considering there is both a mechanical and natural ventilation system in the room.
