Sonata Vent Silencers are used to attenuate noise produced by the expansion of Gas & Steam from elevated pressures to atmospheric pressure.

Vent Silencers are an effective way of reducing high frequency noise produced at start up or when venting to atmosphere.  Sound Control has specific designs for either commissioning/steam blow or permanent operation projects.

Performance of Vent Silencers is achieved by a 2 stage noise reduction approach.

  • Stage 1 – provides sound reduction via the inlet diffuser. The diffuser is effective in attenuating frequencies of sound and distributing the flow evenly to the 2nd stage.
  • Stage 2 – sound reduction comprises of absorptive elements positioned within the silencer case thus absorbing acoustic energy out of the gas stream prior to exiting to atmosphere.

Design features of Vent and Blowdown silencers may include:

  • Inlet diffuser:
    • Design – AS1210.
    • Welding – AS3992, AS4041.
    • NDT – AS4037.
      • 100% NDT completed on all inlet diffusers manufactured by Sound Control.
  • Noise Attenuation upwards to 30 dB(A) depending on flow and temperature conditions.
  • Flanged Single or Multiple Inlets.
  • Multi-stage diffuser designs available.
  • Acoustically lined cases with absorptive elements.

sonata_acoustic_materials_-_on_products_pageSound Control have available a range of Sonata Acoustic Materials, which can be used in a multitude of installations and are designed to provide varied Acoustic Performance. All products are fully tested and approved for all Australian conditions, and to assist we can provide comprehensive product data on request.

Use of Soundproofing materials is when reduction of structure borne noise is required in Transport vehicles such as Locomotives, Luxury Marine Cruisers and Road Transport such as Buses, Ambulances, Truck Cabins, Off-raod and Earth-moving Equipment. Soft absorptive treatments are used to reduce undesirable extended reverberation times (echoes) within spaces such as that found in public areas, recording studios, auditoriums, teaching facilities, restuarants and shopping centres.

A vast array of noise problems can be solved with the correct choice of materials or custom made products designed to suit the environment intended. Sound Control’s extensive knowledge and experience will assist in design and consultation of the selected product as well as providing full costing analysis.

We use and distribute the range of “Soundguard” product, a leader in the Acoustic Materials Industry, manufacturing some of the most advanced materials available in the world today.

Product Identification:

  • Sound Absorbing foams
  • Composite sandwich barrier/foam product
  • Dampening sheet and sound paint are all used in a diverse range of industries.

sonata_acoustic_panels_-_on_products_pageSound Control Pty Ltd manufactures and supplies a comprehensive range of different types of Sonata Acoustic paneling designed to suit applications within any project where sound absorption, aesthetics and practicality for function is needed. If the objective is to enhance the properties of sound by improving speech clarity and sound quality, the answer is sound absorption.

These panels can be supplied pre-finished and custom sized to match any décor in fabric finishes, timber veneer or painted metallic finish. Utilizing materials manufactured by leaders in the Acoustic Textile and Fabric Industry, Sound Control is able to deliver a solution to any noise problem. All products used conform to AS1045-1998 “Measurement of absorption coefficients in a reverberation room” and can be issued with Material Data Sheets.

High ceilings and Large open spaces amplify sounds that bounce off hard reflective surfaces, creating echoes and increased noise levels. To reduce these effects, sound absorptive materials are essential and can be provided in various forms for the function intended. Typically metal coverings with absorptive infill’s are used in industrial situations such as plantrooms where soft fabric or architectural coverings are used in commercial applications.

Traditionally, metal faced acoustic lining systems comprise of an absorptive lining being secured to the intended surface and faced with a heavy duty perforated metal covering. Use of formed metal sheeting has allowed larger spans and coverage of areas to be achieved with reduced installation time. As with most metals, corrosion and surface protection finishes are paramount with stainless steels and powder coat finishes being an alternative to standard Galvabond finishes. Higher corrosive resistance materials such as “ZAM” or Stainless Steel, including a non-staining ferretic Stainless Steel, can be supplied upon request.

A new range of sound absorption materials for wall and ceiling linings is also available where utilization of Thermal-bonded Film is supplied in board format, providing exceptional sound absorption capacity and high durability in hot and humid conditions.

Application of vibration damping materials to structures and panels dissipates the vibrational energy.

Sound Control distributes the “Soundguard” product range and has used it extensively.

The primary effects of damping treatments are:

  • Reduction of vibration amplitude at resonance.
  • A more rapid decay of free vibrations. This avoids the accumulation of energy due to a series of impacts.
  • Attenuation of structure-borne noise propagating along and through structures.

Examples of resonant vibration involving repeated impacts:

  • Materials falling into and onto holding vessels or hoppers
  • Chutes and ductwork that are pneumatically conveying particles such as rock, stone or wood-chip.

They are provided as:

  • sprayable compounds
  • flexible sheets
  • self adhesive
  • 2 pak paint on
  • heavy duty tiles

When discussing Mounts and Isolation Materials, it is useful to identify the three basic elements of the dynamic systems that will provide the best solution:

  1. The equipment (component, machine, motor, instrument, part etc)
  2. The support structure (floor, base-plate, supporting structure)
  3. The resilient member referred to as the isolator or mount (rubber pad or spring) which is interposed between the equipment and the support structure.

Structure borne noise is a major problem in all transport vehicles whether in the sea, land or sky and at Sound Control, we have a wide range of vibration damping treatments to reduce the noise path. Specialised isolation mounting systems are supplied to manufacturers of Locomotives and Luxury Marine craft, needing reductions to assist in shock and vibration control.

Sound Controll distribute a range of Barry Control mounts and others sourced for very specific use.

Applications:

Studios, Universities & Teaching Institutions, Interview Rooms, Concert Halls,  Building Services, HVAC Systems, Trucks, Boats & Planes, Mining & Processing Equipment, Airports, Machinery Enclosures, Aesthetic & Architectural Applications, Marine Industry, Road and Rail Vehicles, Agricultural machinery, Building and Construction sectors, Manufacturing Industries, Commercial and Residential buildings.
