Acoustic Modelling
Accurate Modelling Lets Us Identify and Mitigate Issues Before They Exist
Noise Prediction Software is an essential tool in the assessment of noise impact, or acoustic performance of a new-building. Using state-of-the-art acoustic modelling software, we're able to listen to how spaces that don't yet exisit will sound once built, identify noise constraints on a proposed developmnet, and accuratley predict the benefit of acoustic mitigation.
At JPM Acoustics, our suite of software packages allows us to offer a full range of acoustic modelling services to complement our projects.
Our modelling capabilities include the following:
- CadnaA. 3D Noise mapping software for predicting noise propogation outdoors
- Insul. For predicting the sound insualtion performance capabilities of building materials. Can simulate the sound level difference between rooms.
- CATT-Acoustic. Ray tracing software used for predicting how sound will behave in a space. Can be used to listen to what a space will sound like before it's been built.
How Does Modelling Software Help Us?
In nearly every project we assist with, a noise and / or vibration survey is required. Whether it’s to assess the existing noise environment at a sensitive location where a noisy development is planned, or to measure a noise source similar to what will be installed on a new site, accurate measurements are essential.
Below is a typical (non-exhaustive) survey scope for various types of assessments:
- New Residential Development. We may need to measure existing noise levels on-site at locations representative of where new homes will be built. This helps us assess the suitability of the site and, if necessary, recommend mitigation measures such as noise barriers or house re-orientation to shield noise-sensitive areas from nearby sources.
- Proposed Noise-Generating Development. When assessing the impact of a new noise source, it's important to understand the prevailing background noise levels at nearby properties. We then predict the noise from the proposed source—such as mechanical plant or delivery bays—and compare it with existing noise levels to evaluate potential impacts.
- Commissioning Testing. Noise surveys are often required during the commissioning of noise-generating equipment, machinery, or processes. In these cases, it’s crucial that our surveys capture data in line with the relevant standards referenced in the commissioning documentation.
- Vibration and Re-Radiated Noise from Gyms. Noise and vibration from amplified music and weight drops in gyms are frequent sources of complaints in mixed-use developments. At JPM Acoustics, we have extensive experience in measuring noise and vibration levels from operational gyms, as well as simulating gym activities in existing buildings. This allows us to provide expert advice on effective noise and vibration control strategies to minimise impact on neighboring properties.
