Power generation is a very cost-competitive industry. With engine noise levels typically about 110 dB(A), it is a challenge to reduce noise levels economically. In addition, the acoustic materials are exposed to high temperatures, potential fluid or fuel spills, engine maintenance and a high air-flow environment.
Megasorber has taken on these challenges and successfully developed a range of soundproofing products and systems to suit various requirements. With Megasorber's unique Soundmesh® G8 facing, it is possible to have a fireproof, tough, durable as well as sound-absorbing material.
Megasorber soundproofing systems are compact and light weight. Typical systems consist of two key components:
- Megasorber FG range or Megasorber P range products for air-borne noise absorption, and
- Megasorber D14 for low frequency structure-borne noise reduction. It is a 1.5mm thick self-adhesive constrained layer damper.
Soundproofing Systems
- Economical soundproofing system: line enclosure with Megasorber FG.
- Compact soundproofing system: apply Megasorber D14 to cover about 60% of the total area then line enclosure with Megasorber FG.
- Super quiet system: line the enclosure with Megasorber C50BKA, 50mm thick soundproofing foam-barrier-foam composite material with fireproof acoustic facing.
The following applications highlight just a few ways Megasorber customises soundproofing solutions:
Soundproofing Lining for Power Generator Enclosure
Originally, glasswool and perforated metal had been used to line the enclosure. Over 24 months of operation, the genset became very noisy as the glasswool gradually erroded away. As a result, the genset needed refurbishment. Megasorber FG25BKA, acoustic foam with a fireproof sound-absorbing facing and self-adhesive backing, was specified by the customer.
With Megasorber
FG25BKA, there is no need for perforated metal or glasswool. Megasorber
FG25BKA is a simple 'peel and stick' installation which does not require welding or riveting of any perforated metal sheeting.
As a result, our client has subsequently increased their production output as well as gained significant labour cost savings during the installation process. Megasorber FG25BKA can also help you to achieve an increase in your factory output as well as cost savings in soundproofing installation.
If a lower noise level is required, then the thicker Megasorber FG50BKA is recommended. With the unique Soundmesh® G8 fireproof acoustic facing, Megasorber FG50BKA provides excellent sound absorption at low frequencies, typically with a peak sound absorption from 250Hz to 2,000Hz.
Durable Soundproofing System for Australian Defence Force Gensets
The Australian Defence Force's gensets have a very high and stringent specifications: insulation material MUST survive up to 150°C for 6 months duration. The army placed their full confidence in the proven Megasorber materials.

Compact Soundproofing System for Blower Enclosure
Megasorber was
asked to reduce a very low frequency tonal noise from an acoustic enclosure for blowers. The enclosure was
extremely bulky and heavy due to the low frequency noise requiring a very thick glasswool to absorb such
noise. The glasswool or rockwool must be covered with perforated metal sheet, making it very expensive to construct.
Using the Megasorber 4-Fold Approach® we helped our client develop a compact and light-weight Megasorber soundproofing system (see photo on right) consisting of:
- Megasorber D18-3A, self-adhesive vibration damping sheet (Megasorber D14, constrained-layer vibration damping sheet can also be used)
- Megasorber FG50BKA, acoustic foam with fireproof sound-absorbing facing and self-adhesive backing
The Megasorber soundproofing solution was a very simple 'peel and stick' installation. Significant cost savings were achieved by reducing the enclosure size and soundproofing installation costs.
Compact Soundproofing Solution for 1,200 KVA Genset Enclosures
Measured at 115dB(A), the engine generates high level of air-borne noise. Even with well designed engine isolation mounts, there is still a high degree of vibration of the enclosure panels, radiating out high level of low frequency structure-borne noise.
The Megasorber compact soundproofing system can consist of:
- Megasorber D14, a self-adhesive constrained-layer vibration damping sheet, applied onto the metal structure first (see photos below) to reduce the low frequency structure-borne noise effectively.
- Megasorber FG50BKA, P50BKA or P100BKA applied onto the top to provide much needed noise reduction of the air-borne noise. FG50BKA is an acoustic foam with our unique Soundmesh® G8 fireproof sound-absorbing facing and a self-adhesive backing. P50BKA is a sound-absorbing polyester-wool with Soundmesh® G8 fireproof acoustic facing and a self-adhesive backing. P100BKA is a thicker version of P50BKA.
Compact system: (1) application of damper D14; (2) application of P100BKA; (3) typical finish
Soundproofing Solutions for Genset Rooms in Hospitals, Libraries and Other Buildings
Traditionally, these gensets rooms are line with glasswool or rockwool with perforated metal sheets. This system is difficult and expensive to construct and operators are experiencing a lot of Occupational Health & Safety (OHS) issues. The stringent fire regulation on buildings under Building Code Australia (BCA) has, however, made it almost impossible to use any alternative materials such as polyurethane foam.
Megasorber is very proud to provide a unique soundproofing solution to this challenge. The solution consists of:
- Megasorber P100 (or P50), a sound-absorbing polyester-wool with Soundmesh® G8 fireproof acoustic facing
- Fast and safe installation methods
(1) soundproofing of an engine room with P50BK; (2) plastic pins on wall panels; (3) splitters with P100BK
