Soundproofing for Reclaimer Operator Cabin Port Kembla Coal Teminal

Reclaimer Operator Cabin Soundproofing

Location: Port Kembla, Wollongong NSW

Noise Problem

PKCT operate two Reclaimers with the operator's cabins located close to the bucket wheel and drive components. Cabins were fabricated from 5mm steel plate with checkerplate flooring. There were no provisions for noise barrier or noise damping. As a result, operators were subjected to excessive noise. The noise was typically low frequency.

Soundproofing Solution

Armed with Megasorber's unique 4-fold Approach technique, Megasorber engineers worked closely with the PKCT project engineer. A cost-effective soundproofing solution was designed and implemented:

  1. Clean All Substrates with Megasorber AC5 Adhesive Cleaner to maximise the adhesion.
  2. Soundproofing Floor: Adhere 2 layers of D14 to the underside of the floor panels.
  3. Soundproofing Cabin Wall and Ceiling: Apply 2 layers of D14 then FG50GRA acoustic foam, on top of the D14.
  4. Soundproofing Floor Cavity: Place Megasorber C50 inside the cavity under the floor.
  5. Soundprooding Access Door: Apply 2 layers of D14 to the door panels then FG50GRA on top of the D14.
  6. Seal the Joins between the foam panels with matching colour G8 Grey Tape.

Soundproofing Result

Aesthetically pleasing, with an outstanding sound and thermal reduction: a total of 12 to 13 dB(A) noise reduction after the installation of Megasorber's soundproofing solution. (See our Understanding Noise Levels page to better understand how significant a 12-13 dB(A) noise reduction really is!)


Hi Harvey,

We collected noise data pre-works and post-works and were able to achieve an overall noise reduction inside RC1 Operator's cabin of between 12 - 13 dB(A).

The work has been successful both in terms of noise reduction, improved thermal insulation and overall aesthetics.
