Sound insulation, sound barriers and noise enclosures.

Noise at work can lead to serious health risks for both your workers and the wider public. Excessive noise can make warnings harder to hear, interfere with communications and lead to a range of long-term medical conditions.

RVT Group’s acoustic barriers and temporary noise barriers for hire will help in protecting your construction workers and reduce public noise and provide overall control of noise on construction sites.

Soundex Acoustic Barriers

Temporary acoustic barriers are the ideal way to reduce noise on site. By positioning a noise barrier as close as possible to the noise source, you break the line of sight, and reduce the audible noise level outside the work zone.

RVT offer a wide range of acoustic solutions which are available to hire.

Manufactured in the UK

All Soundex products are manufactured to ISO 9001, ISO 14001 and ISO 45001 standards in the UK, ensuring that the highest standards of product quality are maintained.

The Source of Noise on Site

Harmful noise levels are created by a wide variety of machinery used during site activities including cutting, wall chasing, drilling, grinding, blasting, piling, excavation and breaking. Activities over 80dB are considered unsafe and every decibel has a permissible exposure time.

Some of the most common sources of noise on construction sites come from:

  • Jackhammer Drill at 125dB - which can cause damage after just 3.5 seconds of exposure.

  • The noise generated from saws, cutting equipment and hand-held breakers can easily exceed 100 dB.

  • Pile driving often measures between 115-132dB

  • Diesel generators and excavators, with breaker attachments, can produce readings of well over 80 dB.

  • Small generators and compressors can also produce high levels of noise at low frequencies, meaning that the noise can travel across longer distances and cause disruption across wider areas

Whilst the operator of such equipment will be protected by PPE, the protection of other workers and nearby members of the public will require further measures.

Failure to provide effective noise control measures in construction, especially whilst machinery, such as the above, is in operation can result in irreparable damage to your workers’ hearing.

The Health Risks

Uncontrolled noise can drastically effect workers’ health; hearing loss can be gradual and, by the time most sufferers notice a change, it is usually too late. Therefore, a lack of adequate noise control on site could result in claims for hearing loss and tinnitus in the future.

Results of exposure to dangerous noise levels can also go beyond this. Losing one of your key senses can induce many long-term debilitating illnesses and conditions such as psychological stress, fatigue, anxiety and depression, impaired memory, and social withdrawal. Subsequent reduced job performance and loss of earning power can also be devastating. As with hearing loss and tinnitus, many of these long-term effects can take time to develop.

Managing Noise on Site

RVT believes that effective noise control can be managed in three easy steps:

  • Capture the hazard - Position the acoustic barrier close to the noise source (fully enclosing it if possible) to maximise the acoustic shadow area.
  • Contain the hazard - Block the line of sight by ensuring the noise barrier is seamless. You may wish to consider whether an enclosure would be more suitable for fully containing the noise.
  • Control the hazard - Use high quality noise barriers, with high sound attenuation, to absorb excessive noise. Screening reflective surfaces like walls may also help to reduce noise bouncing the sound over the barriers.

Noise Control FAQ's

Learn More About Noise Control

What is the maximum noise exposure limit in the workplace?

According to the Control of Noise at Work Regulations 2005 (the Noise Regulations), the level at which employers must assess the risk to workers' health and provide them with information and training is 80 decibels. The level at which employers must provide hearing protection and hearing protection zones is 85 decibels (daily or weekly average exposure). The regulation also details an upper exposure limit value of 87 decibels. For more information please read the regulation in full.

What is the standard size of an acoustic curtain?

Sizes vary, however RVT offer the Soundex Acoustic Curtain which is 1250mm x 2500mm and the Soundex Acoustic Quilt which is 3600mm x 2050mm (which is designed to fit a standard security fence panel).

With regards to noise, what does it mean to ‘break the line of sight’?

Simply, it means to put a barrier in place so that the source of noise cannot be seen; by its very nature, this will reduce the noise heard by those on the other side of the barrier (in the ‘shadow zone’). The level of noise reduction will depend on the material and quality of the acoustic barrier being used. A high-quality acoustic enclosure, with walls and a roof, will be the most effective way to reduce noise at source, as there will be no line of sight from any angle.

Is the Soundex Cutting Enclosure suitable for hot works?

All Soundex products are flame resistant, however the Soundex Cutting Enclosure has the added benefit of a cutting bench. It also features a port for extraction to be fitted to remove dust or fumes. These features make the Soundex Cutting Enclosure ideal for hot works.

What acoustic solutions are available to the rail industry?

The Soundex Pile Wrap Attenuator has been designed specifically for the rail industry. This patented attenuator helps to reduce the noise from steel cylindrical piles during impact. Extra strong magnets hold the attenuator to the pile during each impact, while individual attenuators are joined with a Velcro connection, removing the requirement for extra straps or buckles.

RVT also offer the Soundex PyroTech LU Curtain, which was designed in conjunction with the London Underground to the extremely stringent BS6853:1999 standard. The LU Curtain is the only Class 0 fire rated acoustic barrier currently available which can be used in sub-surface environments, including areas within the London Underground.

Furthermore, the Soundex Micro Enclosure is often championed for track cutting. It is quick to erect and is available with GRP frames for working near live electrics.
