Echo Barrier H4 Noise Barrier

Home/Products/Noise Barriers/Echo Barrier H4 Noise Barrier

The Echo Barrier H4 noise barrier represents a very innovative and effective solution to a series of common construction site and event noise problems. The technical advances included in the design of the Echo Barrier acoustic screen not only affords a high level of acoustic performance, but they also negate the practical problems and hassles associated with the use of traditional temporary acoustic barriers

In practice, this means very rapid fitting and removal (by one man), simplified transport and storage, and an acoustic screen performance that is without equal. As a result, the Echo Barrier is a key part of current best practice for site and event noise management.

In addition to its acoustic qualities, the Echo Barrier H4 has been designed to look good in prominent and highly visible locations. Furthermore, clients can take the opportunity to advertise their brand name or services on the Echo Barrier H4 barrier itself.

Features

Echo Barrier H4 anatomy

The acoustic elements of the Echo Barrier H4 Noise Barrier comprise a mass layer and a carefully designed acoustic absorbent layer. These not only attenuate the direct transmission of sound, but also absorb it, thereby reducing the sound reflected back towards the source and overall performance.

Typical octave band noise levels with and without the barrier are shown in the following figure:

The Echo Barrier H4 is typically mounted onto existing fencing or scaffolding. Care should be taken during installation so that the acoustic barrier is positioned as close to the noise source as possible in order to maximise the performance of the noise barrier.
