3. Noise Propagation Modelling
The noise measurements recorded when Village Bicycle is operating do not represent the true noise
emissions from the cafe, because other noise sources were present in the environment. The Village
Bicycle operational noise emissions must be considered in isolation from the general acoustic
amenity at the surroundings. Therefore, noise propagation modelling using Sound PLAN software
was used to calculate the operational noise levels.

A 3D noise propagation model was developed using SoundPLAN software, considering the terrain
characteristics around the investigated site, and site specific noise measurements and observations.
The intent of the noise propagation modelling was to assess the operational noise attributed to the
operation of Village Bicycle cafe at the nearest noise sensitive place (Boftlebrush Townhouses) and
to design noise control measures.

3.1 SoundPLAN 3D Model

Extract from the SoundPLAN model, presenting the topography, the location of Village Bicycle cafe
relative to the nearest commercial and noise sensitive places, are presented in Figures 3.1, 3.2 and
3.3.
