What do you mean by acoustics of buildings? Suggest four steps that can be taken, while constructing buildings, to avoid problems that may occur due to multiple reflection of sound.

Acoustics of buildings-It is the part of the engineering science which study or deals about problems or factors for the clear audibility of the buildings.

Four steps to avoid problems caused by multiple reflection:-

•Use of sound absorbing material for the construction of the building.

•Tight packing of the building for cancellation of the outer noise.

•Make the floor of the building/hall rough.

•The design of the ceiling matter the most, if one want to increase multiple reflection the ceiling should be curved while for less reflection ceilings should be flat.
