Distributed by Supply Force International
We supply temporary acoustic fencing for New Zealand’s construction and industrial industries
World-leading Temporary Noise Barriers
Designed to treat your noise source, not simply surrounding your entire perimeter.
Less noise, fewer complaints, more work
An alternative to traditional plywood hoarding–which reflects sound and vibration and can effectively double the initial noise level. Echo Barrier is a tested and proven noise barrier system for reducing noise by absorption, to the extent of up to 40 dB!
For superior workplace sound protection
Echo Barrier is supplied to the NZ market by Supply Force International. Echo Barrier has the correct solution for all of your noise issues on site. Our barriers offer the best weight to noise reduction available. So, if you need light weight barriers that are easy to move around site or heavier mass solutions to meet consent requirements, we have the solution.
Due to the superior build quality of the Echo Barrier, we are able to offer the lowest hire rates in the market- guaranteed.

Today, all contractors have a responsibility to protect both the public and the employee from hazards
All contractors in the construction industry face challenges of noise and dust management. Some contractors have a better culture than others when it comes to managing such challenges. It really depends on the health and safety culture of the contractor and how health and safety policies are implemented in daily site life.
Workers on site will often be wearing hearing protection to perform their task. If the only thing separating the public from the work site is a site fence, then it is possible that public will also need to protect their ears as they walk past. Safety professionals refer to this as a walk by hazard.
Identifying hazards and managing risk
While the safety act encourages employers to identify hazards and manage risk, the onus is on the designer to plan ahead for hazards at each stage of of a construction project. Echo Barrier is simply the best product on the market for protection against noise hazards and construction site dust.

Echo Barrier is hand-made in Europe
Echo Barrier was founded by Peter Wilson, an acoustics expert with over 30 years direct experience in acoustic engineering. An industry pioneer, Echo Barrier is dedicated to innovative thinking underpinned by R&D, and attention to detail in all aspects of material selection, engineering and design. By combining acoustic absorption and insulation technology, using high-tech, lightweight, exceptionally durable materials—Echo Barrier products are the epitome of acoustic engineering.
Echo Barrier leads the world in combating noise pollution with its modular system of portable acoustic panels.
Decibels, noise attenuation and the human ear
Noise levels are measured in decibels (dB). Since the decibel is a logarithmic (non-linear) unit of measurement, noise attenuation of ‘just’ 3dB is equivalent to a substantial reduction in noise energy, i.e. 50% yet that reduction is only just perceptible to the human ear. If noise attenuation increases to 10dB, it equates to a reduction in noise energy of 90%; the human ear senses that as noise reduction of 50%.
The chart below places this in the context of the performance of Echo Barrier’s H Series of acoustic panels. Taking this further, the chart makes clear why, in the field (on site), it becomes difficult to attenuate noise by more than 20dB.
Especially important is that noise reduction of 20dB equates to energy reduction of 99%, yet the remaining 1% of energy represents 25% of the noise level perceived by the human ear.
|Decibel Reduction (dB)||Energy Reduction (%)||Noise reduction as perceived by the human ear|
|10||90||Sounds 50% as loud
(Reduction of 50%)
|20||99||Sounds 25% as loud
(Reduction of 75%)
|30||99.9||Sounds 12.5% as loud
(Reduction of 87.5%)
|40||99.99||Sounds 6.5% as loud
(Reduction of 93.75%)
Key factors in successful noise attenuation
There are FOUR key factors that determine the noise attenuation achieved by a barrier of any kind
The position of the barrier in relation to the noise source.
2. Noise absorbtion
The degree to which the barrier absorbs sound, rather than simply reflecting it. When noise is
reflected, it can reverberate, aggravating noise pollution.
3. Barrier mass
Greater mass offers greater noise attenuation (i.e. results in greater transmission loss), but for the
sake of practicality, a barrier also needs to remain manageable in terms of its size and weight,
especially if it is to be portable.
4. Barrier aesthetics
If barriers are manufactured to a high standard and present a professional image, the perceptions of their performance can be considerably enhanced.
