Insurance for an Effective Solution
The GER acoustic study (Noise Impact Assessment) is a tool for determining the extent to which the installation of a Greenwall noise barrier can mitigate noise pollution. An independent acoustic consulting firm calculates the expected noise reduction in your specific situation.
Research
In consultation with a Greenwall consultant and the client, the desired position, height, and length of the Greenwall® noise barrier are determined. In addition, (satellite and environmental) photos and any drawings, designs, or maps of the surrounding area are sent to the acoustic engineering firm.
Based on this data and the data on the noise source—which the acoustic consultant often already has at his disposal—the Geonoise software program is used to calculate the expected effect of the planned Greenwall® noise barrier.
Result
The result is documented in a report, expressed as the number of dB of reduction compared to the current (baseline) situation. Greenwall typically receives the report within 10 business days and can then discuss it with the client.
The study may also reveal that installing a screen is not effective enough, or that the screen needs to be placed in a different location or be of a different size to be effective.
Incidentally, this memorandum has no legal standing under the Noise Pollution Act. A full acoustic study (wgh) must be conducted for that purpose.
Investment
An acoustic study is always an investment: it answers the question of how much noise the noise barrier will reduce, and it protects you from making an expense that won’t pay off.
