The Penny Farthing Pub is an “Olde Irish” style Pub located in the heart of Oak Bay Village in Victoria, BC. Wakefield Acoustics Ltd. were asked to examine the potential for noise from a proposed outdoor patio to disturb nearby residents. The state-of-the-art sound propagation modeling software CadnaA was used to create a three-dimensional model of the Penny Farthing, proposed patio and the residences located in the lane behind the pub. The computer model was used to estimate the noise levels at the residences that might be expected due to several pub patrons conversing loudly on the patio. It was then possible to use the model to optimize the height of walls that would surround the patio in order to control the spread of noise to the residences.
