Acoustic Wall Panel
The importance of reflection sound in auditorium, music hall and multipurpose hall and conference room as been known for many years. The contribution to solve reflection sound which is we can call it as echo is recognized to the extent that designers and builders of such halls must take special care that there will be a proper supply of such reflections. SI Acoustic Wall Panel can be apply at auditorium, studio, lecture hall, cinema, office, home theatre, banquet hall and others.
audiometric room/booth
A major component necessary for a good hearing test is sufficient quiet in a test room or booth. SI Audiometric Room/Booth will be constructed to meet the minimum noise restrictions within a test environment to obtain a valid test according to the maximum allowable sound level stated by Department of Occupational Safety and Health (DOSH). SI Audiometric Room offer perfect atmosphere in the audiometric room which consists of good ventilation, observation window, lighting and aesthetic design to help audiologist/doctor serve their best to their patient.
acoustic door
Si Acoustic Door sets provide a sound privacy in office, commercial and industrial environment. Our highly qualified engineers will advised on acoustic application and assist with calculation for specifications. Si Acoustic Door has two materials which are Steel and Timber that come with acoustic door seal system and ironmongeries for soundproofing you actually need.
studio
There are too many types of studio such as recording studio, mixing studio, audio video and many more. Studio is a system which the whole things needs to be balance. The general requirement of a studio should be carefully thought about before location is chosen such as floating floor, acoustic sub ceiling, wall angle and silent ventilation system. Good sound isolation is essential and many people greatly underestimate its importance.
anechoic chamber
An anechoic chamber is a room designed to complete absorb reflections of either sound or electromagnetic waves. This room are also insulated from exterior source of noise. It can be designed to provide ambient sound 20dB(A) and below. This type usually use for sophisticated testing.
industrial
acoustic canopy
SI Acoustic Canopy is fabricated to comply with the noise level requirement set by DOSH and DOE and is designed to meet the requirement of acoustic performance and ventilation simultaneously. SI Acoustic Canopy will be installed with acoustic items such as duct silencers, exhaust silencers, acoustic panel and acoustic door. It can be applied to house gensets, compressors, pumps and other internal combustion engine that emits high noise level.
acoustic enclosure
SI Acoustic Enclosure is designed to reduce noise level up to client’s requirement. SI Acoustic Enclosure come with versatile design that has panel modules to fit various applications such as manufacturing machine (press, stamping, and injection), sound testing room and others. SI Acoustic Enclosure is constructed using galvanized iron and has powder coated epoxy as the finishing that come together with acoustic door, observation window, air conditioning system and other features.
exhaust silencer
SI Exhaust Silencer is applied to reduce exhaust sound effectively that arise from gensets, compressors, pumps and other machinery powered by internal combustion engines. SI Exhaust Silencer is manufactured using high quality steel plate to ensure meet most installation condition. Connection flanges follow to ANSI, JIS, DIN standard or custom made to meet site condition. Software aided calculation is used to determine pressure drop across exhaust silencer.
duct silencer
SI Duct Silencer is used when ventilation is required and at the same time acoustic performance also be to be achieved. SI Duct Silencer is constructed with galvanized iron (G.I) body and mild steel angle iron frame. Acoustic performance is determined by the length of duct silencer. SI Duct Silencer can be applied for room or canopy ventilation system and building air conditioning system.
spark arrestor
SI Spark Arrestor has a same construction materials with exhaust silencer, but come with additional internal construction. Spark Arrestor is used to trap particles emitted from internal combustion engine and stored in soot collector. SI Spark Arrestor is manufactured using high quality steel plate to ensure meet most installation condition. Connection flanges follow to ANSI, JIS, DIN standard or custom made to meet site condition. SI Spark Arrestor also available in stainless steel.
acoustic barrier
SI Acoustic Barrier is made by perforated galvanized sheet in both side of panel and pack with high dense acoustic infill. Barrier finishing is either power coated epoxy or marine spec coating systems depend on the location of the installed barrier. SI Acoustic Barrier is effective to reduce noise from motor vehicle from road traffic or construction noise towards residential area.
vent silencer
SI Vent Silencer is applied to silence high-velocity and high pressure fluid that vented to atmosphere which create excessive noise level. SI Vent Silencer is custom made based on client’s requirement. It is constructed with heavy duty hot rolled boiler plates. Non-destructive test is performed to ensure welding meet required specification.

noise monitoring
Noise Exposure Regulation 2019 in Regulation 3 stated that it is employer duties whether his employee may be exposed to excessive noise in the workplace.
As contained in Regulation 6, no employee shall be exposed to daily noise level exceeding 85dB(A) or daily personal
noise dose exceeding hundred per cent; the maximum sound pressure level exceeding 115dB(A) at any time; or the peak sound pressure level exceeding 140dB(C).
SI Noise monitoring will be conducted by using our latest equipment which are Sound Level Meter (SLM) for workplace or environment and Dosimeter for direct noise exposure to employee.
Noise Control Study
Regulation 4 of Noise Exposure Regulation 2019 stated employee to appoint a noise risk assessor to carry out Noise Risk Assessment if his employees may be exposed to excessive noise and then it need to be reviewed not more than 5 years from the date of the previous noise risk assessment.
Upon completion of the Noise Risk Assessment, our noise risk assessor will prepared a report and submit the report to the employer which include all the finding and recommendation needed.
dosh submission
Our service cover of internal room ambient, document preparation and submission to DOSH for approval. The applied room for audiometric test should comply with the noise level as stated by the DOSH.
Audiometric testing should be conducted annually as per mentioned in the Industry Code Of Practice (ICOP) For Management of Occupational Noise Exposure and Hearing Conservation 2019.
doe submission
Prior to installation of generator set, owner need to submit set of documentations together with written notification under Regulation 5 of Environmental Quality (Clean Air) Regulation 2014. We can work on behalf of the owner to prepare the documents that include PE stamping drawings, calculations and catalogues. Our experience know how to make all the process go smoothly.
