Occupants’ responses on rain noise underneath metal deck roof system

The design of metal deck roof system should incorporate some sound insulation materials if it were to insulate structure borne impact noise such as from the rain, transmitted into a building. The noise from the rain may affect the ambient noise level within the space underneath the roof thus affect the occupants’ comfort. Thus, this paper would like to examine the relationship between the annoyance responses with noise disturbance on occupants’ activities and side effects face by occupants’. The result reveals the impact from rain noise amplified by metal correlated with annoyances which cause uncomfortable condition to the occupant.
