The use of computer generated simulations and assessments help us identify potential issues and offer suitable resolutions at the earliest possible stage of the project or development. These are undertaken through Acoustic Modelling and Noise Mapping, depending on the space or area required to be assessed.
We frequently use acoustic modelling and simulation to predict how a space will react when a sound (or sounds) is placed or encountered within the environment. The use of specialist software can help us to predict and visualise how sound will propagate within a space or the effect it will have over an area.
Used to calculate, present, assess and predict environmental noise and when an environmental noise assessment may not be the most appropriate course of action. Results are shown in 2D and 3D formats and consist of a colour contour line depicting intensity of noise at different distances from the noise source.
Used for room acoustics and auralisation. The room is recreated as a 3D model using SketchUp or similar application. ‘Real’ sounds are inputted in to the program and the results are generated in a format that helps us to visualise how sound will propagate within the room. The final model will help identify potential reverberation and diffusion issues (as well as many other acoustic issues) and allow treatment to be placed in the most effective locations.
Used to help determine the performance levels expected by a material or composite of materials in respect of sound insulation.
Useful when looking at industrial or architectural solutions when needing to predict the sound reduction levels of a product or system where undertaking full laboratory testing may not be possible .
We can also offer a predictive assessment for reverberation based on a spreadsheet generated solution. Whilst not as accurate as a true computer simulation, it does offer enough information to allow a reasonable conclusion to be reached on actual reverberation levels and any treatment required. Assessing a space using these methods are cost effective and provide a guideline to ensure that any reverberation testing required later should meet the performance targets.
Reverberation assessments are ideal for rooms or spaces within schools that already exist and are being refurbished but with time constraints that may not allow for actual reverberation testing to be undertaken. The assessment method gives confidence that the rooms will still meet BB93 once complete.
