Sound Barrier Performance
Echo Barrier employs world-leading acoustic engineers who are constantly researching and developing our acoustical sound barrier products to ensure we remain global market leaders in our sector.
We pride ourselves on providing clients with accurate and realistic information about the performance of our sound absorbing barriers. To help, the following provides some background information on the performance of acoustic barriers so you can make well-informed decisions on what solutions are best to meet your needs.
Please feel free to contact us to discuss any aspect of your own specific requirements.
Note: Be aware that in many instances certain suppliers may provide information based on ‘ideal lab’ conditions – not ‘real life’ conditions.
Key factors behind good performance using sound barriers
To achieve optimum acoustic performance, three factors need to be taken into account:
1. Geometry – the barrier needs to be placed as close to the noise source as possible in order to maximise the ‘acoustic shadow’.
Echo Barrier provides practical advice on optimising your installation for best performance.
2. Mass – the mass of the impermeable material used determines the noise attenuation but only if the barrier is infinitely large. As this isn’t practicable and noise passes over the barrier, there arises an optimum weight/size to achieve optimum attenuation and handling ability.
Echo Barrier products are designed to optimise acoustic properties in real life situations while keeping weight to a minimum.
3. Absorption – a well designed barrier incorporates acoustic absorbent materials on the noise source side to ‘soak up’ the sound and minimise reflections. The material used is important, for instance for safe handling and avoidance of water absorption.
Echo Barrier uses a special high tech absorbent material that is safe, light weight, long-lasting and does not absorb water.
