Acoustic Enclosure for Blowers at Oleon Pulau Indah

 

 

Two nos of blowers were running and the noise emitted measured at 100.6 dBA at 1 meter away. ISTIQ Noise Control was assigned to propose a solution to bring the noise down to below 80 dBA at 1 meter away. 

An acoustic enclosure c/w ventilation fans, lightings, and monorail chain block was installed and the noise level was successfully brought down to 76 dBA.

PERBUDI Masonry Road Barrier at Persiaran Mokthar Dahari

Elevated Highway at Persiaran Mokthar Dahari was built next to Bukit Jelutong residential area. Our client Perbudi Sdn Bhd anticipated that noise from the highway will be transmitted through the housing area once the highway opens to traffic. We were assigned to supply and install Acoustic Mansory Barrier to solve this issue. The length of the barrier itself is 400 meters while the height is 2.4 meters and so far there is no complaint from the residential area on the traffic noise.

Cooling Tower Noise Mitigation at Damansara City

Cooling towers may be the most efficient way of removing heat from a facility but like all mechanical equipment, they create noise. They are efficient machines but notoriously loud and can be disruptive to neighbors especially when it is installed in between high-rise buildings. 

 

ISTIQ Noise Control was called to give a solution on how to mitigate the annoying noise coming from the Cooling Tower. 

A partial Acoustic Enclosure was proposed. Photos above are steel structures were erected to support the modular acoustic panels which enclosed the discharge air of the Cooling Tower. The discharge air are installed with 45 deg bend round duct.

Walls and Roof panels are been installed. 

Air Intake Silencers with 90 degrees  elbow are installed.

Before Treatment

After Treatment

The photos above show before and after acoustic treatment at the Fan Discharge Air of the Cooling Tower. After the completion of the works, the noise level that comes from this side of  cooling tower is noticeably disappeared.

Metal Noise Barrier at Promenade Straits Quay Penang for KERJAYA PROSPEK

Feb 4, 2022
 

 

 

 

During the construction of the “Marine Bridge”, the piling activity had caused disturbance to the residence at Straight Quay. A Metal Noise Barrier was proposed. 


This Metal Type Perforated Noise Barrier is with a thickness of 75mm. The noise barrier is rated at STC 40 with G.I perforated sheet as front casing and G.I sheet as rear casing. Internally, acoustic infill is used as an absorption.


The panel's barrier is installed, supported by I-beam and concrete-based plate. The total length of this barrier is measured at 24m with a height of 4.5m. Noise has been succesfully control with the proposed barrier.


Replacing STEAM AIR EJECTOR SILENCERS at ASTA Chemical, Penang

Feb 3, 2022

Asta Chemical was having an issue where their old Ejector Silencer was not performing as it was supposed to.

Upon investigation, it was most likely due to internal corrosion taking into account that the silencers has been installed more than 20 years ago.

The old silencers were manufactured by a well-known company Burgess Manning, USA

The noise level with old silencers around the area was recorded at 98.3 dBA


Using CFD software, we ran a simulation to see how the flow behave, the integrity of the material, the pressure drop, and the expected noise level.

As soon as we were given the green light to proceed, our fabrication team start the work by procuring the material, cutting, rolling, and welding.

The silencers' requirements were to be painted externally and internally.


After such a long delay due to Covid-19, finally the project resumed and we start the installation in the 2nd quarter of 2021. 


The crane was used to lift the old silencers and then replaced with the new one which was designed and fabricated by ISTIQ Noise Control Sdn Bhd

The silencers were successfully installed as planned and after commissioning the client was satisfied with the overall performance. The noise level after the completion of the works was measured at 84 dBA.


Acoustic Enclosure at HITACHI for FIN Press Machine

Feb 1, 2022

The most challenging design for this acoustic enclosure is the requirement to incorporate the “L” shape sliding door due to the overhead crane.


This enclosure is used to house the FIN Press Machine. Upon completion, the noise level was measured at 80 dBA at 1 meter away as guaranteed.

Single or multiple stamping presses running simultaneously bring sound levels to dangerous levels for prolonged worker exposure. The sound proof box will provide excellent accessibility for product and process, as well as, die change and maintenance.

Our full sound proof box enclosures have a perforated steel skin facing the noisy press and solid sheet steel on the outside, filled with acoustic mineral wool sound insulation.

A steel sound enclosure constructed of removable acoustical panels, doors, windows and ventilation, custom designed and fabricated to meet your application and noise control requirements.
