Create a noise analysis for a housing proposal located adjacent to railroad tracks, then design alternative site solutions to help with noise mitigation.
Transcript

In Forma, you can run a noise analysis on a design proposal,
00:07
and then use the results to design alternative solutions to help with noise mitigation.
00:12
A rapid noise analysis identifies areas of high noise, enabling you to edit your design and view the effects on noise mitigation in real-time.
00:21
You can also view the detailed noise analyses side by side
00:25
to examine the trade-offs of alternative proposals and make data-based decisions throughout your design process.
00:32
In this example of a residential proposal, the site is located right next to a railway, so noise is a significant factor during design assessment.
00:42
To run a rapid noise analysis, in the right panel, click Noise.
00:47
To quickly predict noise for a particular area on your site, in the right panel, click the Analysis area selection menu,
00:55
then select Custom circle.
00:57
Here, clicking to place the center of the analysis shows that, not surprisingly, the noise level near the railroad is relatively high, indicated in red.
01:06
In the Navigator, switch to a different proposal, if needed, and the analysis updates automatically.
01:13
Here, the Alternative 4 proposal is selected.
01:17
One of the benefits of a rapid noise analysis is that you can edit your design and see the updates of the analysis in real time.
01:24
For example, we can replace the row house closest to the railroad and the nearby vegetation with a couple of line buildings.
01:32
With each design change the Rapid noise analysis updates.
01:36
Notice that the added line buildings act as a buffer, reducing the noise near the row houses, as indicated by the greener colors.
01:44
In the right panel, scroll down to see the total distribution of noise, and you see that 48% is now green,
01:51
whereas previously, only 39% was green.
01:55
This means that, by making some quick design changes, you have reduced the noise impacting the site for this location by 9%.
02:03
As you make changes and run analyses on alternative proposals, you may want to view different analyses side by side.
02:11
Trigger the detailed analysis,
02:14
and when the results are ready, navigate to Compare, and then select the analyses you want to view from the left panel.
02:21
For instance, you can review the noise analysis for the recently updated design
02:25
with Line buildings alongside the analysis for the original design.
02:29
In the left panel, expand the relevant proposals to select each Noise analysis.
02:35
Now, you see the noise analyses side by side—on the left, with the line buildings added as a noise buffer,
02:42
and on the right, the original proposal.
02:45
With the color gradients, it is easy to see the differences in these two versions of the design.
02:50
However, placing inspection points enables you to view the exact reduction in noise with the addition of the Line buildings,
02:57
especially for the row closest to the tracks.
03:01
You can also export these views using a screen capture.
03:06
In the visibility and orientation toolbar, click Camera position,
03:11
and then select 4K Screen capture with graphics to download the PNG with inspection points.
03:18
Forma allows you to quickly conduct noise analysis on design proposals,
03:22
make real-time adjustments to mitigate noise, and compare detailed analyses to make data-based decisions in minutes.

In Forma, a noise analysis run on a design proposal can be used to design alternative solutions to help with noise mitigation.
Benefits of a rapid noise analysis:
In this example of a residential proposal, the site is located right next to a railway, so noise is a significant factor during design assessment.
To run a rapid noise analysis:
The immediate result shows that the noise level near the railroad is relatively high, as indicated in red in the canvas. Also, in the right panel under Rapid noise, the percentages corresponding to the color-coded noise levels are reported.
Note: The analysis updates automatically, as do the alternative noise level values under Rapid noise in the right panel.
To see updates of a Rapid noise analysis in real time:
Note: With each design change, the Rapid noise analysis updates.
The added line buildings act as a buffer, reducing the noise near the row houses, as indicated by the greener colors. And in the right panel, the total distribution of noise is now 48% green, whereas previously, only 39% was green. This means that making quick design changes reduced the noise impacting the site by 9%.
To view different analyses side by side:
Note the color gradients and percentage values, showing the differences in these two versions of the design:
