Transport Noise Control

Transport noise control solutions from IAC Acoustics cover a broad range of infrastructure and mode of transport project capabilities.

The design, development and integration of noise control systems is an important consideration during the initial design phase of any transportation infrastructure project.  We offer a wide range of field-proven product configurations which enables our team of experts to engineer a turnkey project solution for you. From tunnel ventilation systems to road noise barriers, we have the technical support in place – acoustic surveys, structural design and engineering, through to project management, manufacture and installation.

Our solutions for mode of transport noise control ranges from off-highway large vehicles for mining and transportation, rail, and marine.  Some of the world’s largest brands, Government and Military rely on IAC Acoustics to deliver noise, ventilation and exhaust treatment solutions, safely, effectively and with performance guranteed.

Tunnel ventilation attenuation is a crucial element of any tunnel system and essential for operational performance, safety and environmental conditions.  Tunnel systems need effective acoustic attenuation in order to manage noise internally, and to mitigate external environmental impact.

Mining noise control of above ground equipment requires specific identification and quantification of noise sources. IAC Acoustics through a variety of techniques including acoustic camera modelling and analysis, can compile a comprehensive noise mitigation strategy for a wide range of OEM mining equipment.

IAC Acoustics Thermowrap thermal insulation blankets are custom manufactured using layered fibreglass materials to provide exceptional heat and noise control at temperatures to 1200°C. Thermowrap thermal insulation blankets will withstand intense vibration and is the solution for traditional block type insulation requiring upgrade or replacement.

Controlling noise pollution from engine exhausts is a challenge for all organisations in the power generation market. It is essential that diesel and gas engine applications have the required noise control measures in place that ensures the facility meets with the relevant noise specification for Health & Safety and the environment.


IAC Acoustics rail traction projects and capabilities cover a wide range of noise control and ventilation system components, which combined provide an effective single-source package:

  • Exhaust systems for diesel traction engines and generators
  • High performance silencers, bellows & ducting
  • Exhaust filters and catalytic purifiers
  • Resilient mounting and supports
  • Thermowrap thermal insulation blankets
  • Air inlet silencers & storm louvers
  • Air inlet filtration & ducting
  • Engine compartment acoustic treatment

Using 3D software and calling upon many years complex high performance silencer design experience, we are able to maximise the available space to fit high performance noise control and engine treatment solutions into restrictive spaces.


IAC Acoustics provides dry and wet marine exhausts for shipboard diesel generators and propulsion diesel engines.  Through products such as the rainmaker water injectors, exhaust gasses can be cooled faster than conventional injectors – this allows the injector to be installed closer to temperature sensitive marine exhaust components, like silicone hump hoses or valves.

Our major customers include military, fast ferries, super yachts and commercial shipping, utilising a range of solutions from our portfolio:

  • Wet & dry silencers
  • Rainmaker & conventional water injectors
  • Water separators
  • Expansion bellows
  • Wet & dry ducting from stainless steel or GRP
  • Resilient mounting and supports
  • Exhaust filters and catalytic purifiers
  • Thermowrap thermal insulation
  • Air inlet silencers
  • Total gas turbine marine exhaust and air intake systems

Our 3D modelling, clash detection and experience in developing exhaust and engine solutions in a range of markets enables us to deliver complex high performance noise control solutions to small and confined spaces.

Transport Products & Solutions

IAC Acoustics supply and install both in-ground and above ground bulk fuel storage and associated pipework. Our Engineers can assist with tank and piping design so that space on site is optimised. Our factory is fully equipped to cope with pipe-bending, welding, metal fabrication and assembly so that on-site fabrication is minimised.

Engine exhaust silencers from IAC reduce engine exhaust noise from all types of internal combustion engines including petrol, diesel or gas. Our exhaust silencers have many key characteristics and attributes including specific applications and are made of a diverse range of materials.

IAC Acoustics Purifiers employ catalyst elements to provide the exhaust purification solution for your diesel or CNG engines. With increasing demand for environmental regulations for the equipment used in industry, IAC Acoustics helps its customers with its unique catalytic converter based solutions that not only meet strict requirements but also keep their engines in service, reliably and cost-effectively.

Our prime mover engine noise control solutions provide you with a comprehensive turnkey solution, covering air intakes, exhaust gases, acoustic enclosures, ventilation, cooling and full M&E fit-out.

Gas turbines require a comprehensive engineered noise control solution to be balanced with significant air intake and filtration package.  Our experience with some of the worlds leading gas turbine manufacturers includes solutions for air intake and exhaust systems, acoustic enclosures, venting, balance of plant and a full turnkey project delivery.
