Attenuators

Attenuators

A comprehensive range of attenuators has been developed to cater to the diverse constructional and performance specifications required in the mechanical services industry.

The attenuator acoustic design is governed by various parameters such as source noise levels, system losses, distances, noise criteria, etc. Understanding the importance of assessing the most economic unit to meet the proper noise criteria, we also consider the practicalities of the ductwork system.

In order to optimise the design, Sound Planning uses HVAC software to analyse the system requirements and plan the appropriate attenuators.

Options
Due to the diverse range of projects undertaken, attenuator construction also includes a wide range of options that can fully cater to various specifications.

Circular Silencer
The circular silencer range is typically used in ductwork systems, where it can be duct mounted or bolted directly onto the fan − if size allows.
Depending on the acoustic requirements, circular attenuators can incorporate a central ‘pod’ that can increase the acoustic performance in terms of insertion loss − attenuators without a pod can only offer acoustic performance at minimal resistance to airflow.

Cross-Talk
Cross-talk attenuators are selected using our calculation software − to help determine the necessary insertion losses, whilst maintaining low system pressure drops (a pre-requisite at this point in the system). This range can either be of rectangular or circular construction.
Acoustic Walls

Environmental Noise (BS 7445)

Environmental Noise (BS 7445)

The 1991 British Standard (BS) 7445 specifies the descriptions and measurements of environmental noise.

This standard serves as a guideline for the necessary procedures and methodologies to be followed by a qualified acoustic engineer. Through BS 7445, acoustic engineers are able to perform a more accurate and traceable assessment.

Performed by experienced acoustic engineers, Sound Planning provides assessments for environmental noise.

BS 7445-1:2003 − Guide to quantities and procedures
This describes the methods and procedures that are practiced when measuring noise − it focuses on the noise of a community, individuals or both.

Results are shown corresponding to the constant A-weighted sound pressure levels. In accordance with BS EN 61672:2003 sound level meters should be a minimum Class 1 or Class 2 and should be adjusted according to the orders of the manufacturer; field calibration should be observed at least before and after each measurement.

BS 7445 also provides advice on selecting the appropriate parameters when recording different types of noise.
Commercial / Industrtial Noise (BS 4142)

Commercial / Industrtial Noise (BS 4142)

BS 4142:2014 − Methods for rating and assessing industrial and commercial sound

Noise can be a big problem for many people − it can be the reason for stress and unproductive operations. It might even be the cause of financial penalties to some businesses.

BS 4142 assesses the potential impact of industrial/commercial noise on residential (noise-sensitive) dwellings. It is established to assess several sources of noise − from a single AC unit to large installations like an oil refinery; it also evaluates the effects to the people nearby, along with the associated risks that can be minimised.

Acoustic instruments have changed a lot since the last 1997 revision. The latest editions consider the advances in technology, which can help to improve the accuracy of final assessments.

According to the BSI (British Standards Institution) group, many sections of the standard have also been revised to improve clarity:
> Helps assess sound levels at proposed new residential premises
> Enables the investigation of complaints by determining sound levels
> Reduces the likelihood of financial penalties
> Supports the current UK planning guidance and Environment Agency guidance

Guidelines for commercial or industrial noise with no distinguishable features
> A significant adverse impact is said to occur if the commercial/industrial noise reaches up to 10 dB or if it is much higher than the background noise level. This kind of situation is reasonably acceptable
> Commercial/industrial noise should be avoided if it reaches 5 dB or much higher than the background noise level
> Normally, it is acceptable if commercial/industrial noise is lower than the background noise level
Sound Insulation Test (Building Control)

Sound Insulation Test (Building Control)

Sound Planning conducts sound insulation tests (impact and airborne) in accordance with Approved Document E of The Building Regulations Act 2000.We also perform Airborne and Impact noise tests in accordance with ISO 140 and provide acoustic calculations and reports in conjunction with ISO 717.

Separating floor noise tests for mixed commercial (ground floor part) and residential (above area) properties, we can also provide advice on appropriate construction specifications if required.

Importance of Sound Insulation
Noise can be very unsettling and disturbing; most buildings in the UK are in need of sound insulation as a mandatory requirement because:

> It can bring peace and comfort
> It helps stop voice leaks
> It prevents further noise inspections
> It increases privacy
> It stops airborne sounds
> It helps to avoid flanking transmissions
> It helps to prevent impact sounds
> It promotes human health and safety in commercial and residential areas (in accordance with WHO 2000 guidelines)
Vibration Assessment (BS 6472)

Vibration Assessment (BS 6472)

BS 6472:1992 − Guide to evaluation of human exposure to vibration in buildings (1 Hz to 80 Hz)
This British Standard provides an overall guide to those who are exposed to building vibration with the frequency of 1 Hz up to 80 Hz.

BS 6472 explains the application of weighting curves, blast-induced vibration and the current methods of assessing continuous, intermittent and impulsive vibration; it also offers guidance on vibration conditions.

Perhaps the most commonly used for environmental vibration assessments, this Standard is commonly used to assess the vibration caused by railways.

Sound Planning provides vibration assessments based on this standard. We provide consulting support throughout the UK to ensure that you conform to government regulations with regards to the environmental impacts of vibrations.

Scope of BS 6472-1:2008
> Application of methods of measuring and evaluating vibration
> Guidance when it comes to predicting the human response to vibration with a frequency range of 0.5 Hz to 80 Hz
> Advice on measurement methods to be employed
> Methods of assessing continuous, intermittent and impulsive vibration
> An acoustic engineer can determine the VDV from frequency-weighted vibration measurements
> Guidance on how people inside buildings respond to building vibration

Benefits of an Acoustic Fence
> Helps to reduce traffic noise
> Serves as a noise blockade between you and the noisy neighbourhood
> Minimises the noise coming from playgrounds, parks, yards or playing fields

WHO 2000 Guidelines for Community Noise
As the World Health Organisation suggests, the control for environmental noise has been hampered by insufficient knowledge of its effects on humans and of exposure-response relationships, as well as a lack of defined criteria.

About 40% of the population of the European Union countries is exposed to road traffic noise; about half of them are exposed to transport disturbances.

Community Noise
Other terms for community noise include:
> Environmental noise
> Residential noise
> Domestic noise

The main sources of community noise include:
> Road, rail and air traffic
> Public works
> Neighbourhood

Main indoor sources of noise include:
> Ventilation systems
> Office machines
> Home appliances
Entertainment Noise (DEFRA, IOA ETC)

Entertainment Noise (DEFRA, IOA ETC)

Conducted in accordance with the Institute of Acoustics’ (IOA) ‘Good Practice Guide on the Control of Noise from Pubs and Clubs’ Sound Planning offers an acoustic consultancy service that can assess entertainment noise.

Good Practice Guide on the Control of Noise from Pubs and Clubs
This applies to both internal and external noise events; it mostly targets entertainment venues that operate twice or more a week. The code also provides different suggested regulations depending on the recurrence of entertainment events and certain noise parameters.

According to the Department for Environment, Food and Rural Affairs (DEFRA), issues relating to Pubs and Clubs include:
> Entertainment noise
> Crowd noise
> Noise coming from mechanical services equipment
> Noise coming from deliveries

Entertainment Noise Assessments:
> Background noise measurements (1/3 Octave)
> Entertainment noise measurement or prediction (1/3 Octave)
> Noise mitigation measures
> Acoustic report
Construction Noise (BS 5228)

Construction Noise (BS 5228)

As the code of practice for noise and vibration control on construction and open sites, BS 5228 refers to the need for the protection against noise and vibration of persons living and working in the vicinity of and those working on construction and open sites.

This British Standard endorses methods for noise and vibration control during construction operations, including procedures that aim to assist acoustic engineers, architects, contractors, site operatives, developers and planners.

The following principal changes have been applied to the British Standards:
> Restructured into two parts −noise and vibration
> Updated information relating to legislative requirements
> Updated information relating to methods and equipment

About us

Founded in 2007, Sound Planning Ltd is a leading sound and noise control consultancy offering a range of services from noise assessments to sound monitoring from environmental and industrial sound pollution.

We predominantly cover both London and the South East of England, however, Sound Planning provide a noise consultancy and noise assessment service with the rates being competitively priced throughout England, Wales and Scotland.

Liasing with local authorities on behalf of clients, Sound Planning discuss the noise, sound and vibration levels with planning officers and environmental health teams when building or houses near industrial areas.

Environmental Noise Assessments:
  • BS 4142 Noise Assessment - Industrial noise affecting residential areas
  • BS 5228 Noise Assessment - Construction noise
  • PPG 24 Noise Assessment - New dwellings near noise
Internal Noise Assessments:
  • BS 8233: 1999 - Internal noise levels due to external noise
Vibration Assessments:
  • BS 6472 -- Human response to vibration in buildings
New build or change of use dwellings often require a PPG 24 Noise Assessment as part of the planning process. PPG24 requires the assessment of existing ambient noise levels for a proposed location; the results of the noise assessment place the location within a PPG 24 noise exposure category or NEC. PPG24 requires a dominant or mixed source evaluation, dominant sources will be either: road traffic, rail traffic, air traffic or industrial noise.

Each noise assessment will be undertaken by fully qualified acoustic engineers; adhering to the relevant British Standard or guidance from the Local Planning Authority.

We then issue comprehensive acoustic noise and sound report, analysing any environmental noise problem and formulating a viable noise mitigation strategy when required.

In addition to our assessments, Sound Planning design, supply and install acoustic enclosures for both domestic and commercial heating systems, ventilation units and air conditioning equipment where noise can be an issue.

Typical Noise Related Problems:
  • Air Compressors
  • Air Conditioning External Condenser Units
  • Air Source Heat Pumps
  • Chillers
  • Fans
  • Generators
  • Industrial Plant
  • Motors
Acoustic enclosure meet the requirements of each application; considering air flow and cooling requirements as well as overall noise reduction performance.

Our acoustic louvres range can be of benefit for projects requiring an attenuated air flow. From HVAC systems, generator enclosures and engine test cells to kitchen extraction systems, workshops and server rooms.
