Acoustic Engineering

All our solutions are purpose built for specific applications. Typically, we work on industrial sized noise problems with projects starting at $10,000. Acoustic components include:

• Enclosures – Considering a holistic solution with fresh air ventilation passive or forced, exhaust and other discharge piping, temperature control, human access, maintenance equipment access, visual access for inspection, condition monitoring, fire-fighting issues, environmental degradation and more.

• Acoustic doors & Windows – Provided as part of a full enclosure solution these can be supplied separately for your existing room with or without acoustic ventilation.

• Louvres – a secure and weatherproof barrier that reduces noise pollution whilst maintaining required airflow with low pressure drop in or out of an enclosed space

• Silencers & Attenuators – Control noise generated by air or gas flows while maintaining specific velocity & volume flow targets for both internal and external application.

• Shock & Isolation Mounting- Machinery mounting can contribute a significant amount to the noise pollution. It can also cause resonance in vibration which shortens the life of your equipment or infrastructure.

• Refurbishment – Acoustic performance can degrade over time. In many cases it is more efficient and cost effective to talk to us about refurbishing your existing noise control apparatus

Industrial Acoustic Silencers/Attenuators

Acoustic silencers plays an important role in noise control and reduces the level of unwanted noise in Industrial Environments and contribute to good work health and safety environments. 

Our acoustic silencers are manufactured to resolve many in-plant noise problems. We are able to provide solutions for: 

  • Vent Silencers
  • Suction Silencers
  • Discharge Silencers
  • Gas Turbine Exhaust Silencers
  • Exhaust Stack With Silencers
  • Steam Vent Silencers for a wide range of pressure and temperature conditions.
  • Start-up Vent Silencers
  • Steam Turbine Exhaust Vent Silencers
  • Process Gas Vent Silencers
  • Natural Gas Vent Silencers
  • Compressor Suction Silencers
  • Compressor Discharge Silencers
  • Blower Silencers
  • Online Pressure Silencers
  • Reactive Silencers
  • Twin Lobe Blower Silencers
  • Motor Silencers
  • Separator Silencers
  • Air Filter Silencers
  • DG Exhaust Silencers
  • Hydraulic System Silencers

Lotus’s Acoustic Silencers Examples:

  1. Circular silencer with mesh air intake for boiler
  2. Stainless steel circular silencers with rectangular transition for air conditioning units
  3. Below is another purpose-designed application by Lotus’s for an acoustic silencer which we undertook for a Development at Barangaroo. This shows the Silencer on top of the ventilation stack. We also supplied several large acoustic enclosures for this project. 

    The acoustic silencer is on top of the chimney in the centre of the photo – the vertical large grey pipe, enclosures are out of sight.
