Buitink TechnologyMobile inflatable noise barriers are used for a variety of temporary noise issues in construction, infrastructure, industry, and events. In practice, this often raises questions about acoustic performance, construction, safety, regulations, and applicability.
On this page, you will find answers to frequently asked questions about mobile inflatable noise barriers. The information is intended as additional explanation and practical clarification of the technical and content-related pages on this website.
FAQs
What are mobile inflatable noise barriers?
Mobile inflatable noise barriers are temporary, modular noise barriers with proven acoustic performance that can be quickly erected without heavy foundations.
When are mobile noise barriers applied?
Mobile noise barriers are used for temporary activities in construction, infrastructure, industry and events where noise pollution towards the surrounding area must be limited.
What is the advantage of inflatable noise barriers over fixed ones?
Inflatable noise barriers are flexible, quick to deploy and can be used without permanent foundations, making them suitable for temporary situations.
How much noise do mobile inflatable noise barriers reduce?
Depending on the configuration, mobile inflatable noise barriers achieve noise reduction of approximately 20 dB to more than 50 dB, based on laboratory measurements.
Are inflatable noise barriers effective at low frequencies?
Yes, inflatable noise barriers are also effective at low frequencies, provided that sufficient mass, water-filled layers and the correct barrier height are used.
What do Rw, C and Ctr mean in noise barriers?
Rw indicates the weighted airborne sound insulation, while C and Ctr are correction terms for mid/high and low frequencies respectively.
How high can mobile inflatable noise barriers be erected?
Mobile inflatable noise barriers are constructed to a standard height of approximately 3, 5 or 7 metres, depending on the application and structural conditions.
How are mobile noise barriers anchored?
Mobile noise barriers are temporarily anchored using anchor pins or ballast solutions, among other things, depending on the surface, wind load and barrier height.
Are inflatable noise barriers safe under wind load?
Yes, inflatable noise barriers are safe in windy conditions when they are used in accordance with their design and are assessed structurally on a project-by-project basis.
Are mobile noise barriers allowed by law?
Yes, mobile noise barriers are often recognised within licensing procedures as an effective measure to reduce noise pollution.
Are mobile inflatable noise barriers suitable for temporary permits?
Yes, mobile inflatable noise barriers have been developed specifically for temporary applications and are well suited to temporary permit requirements.
