A detailed noise study includes noise modeling which enables our engineers to recommend custom mitigation strategies to meet the acoustical requirements of the project.
Our process is flexible and can be adapted to multiple industries and tailored to each client’s individual needs.
Step 1: Data Collection: Monitoring and identifying the source of noise
Step 2: Measure baseline noise level and noise modelling
Step 3: Analysis and Report findings.
Step 4: Recommend mitigation options and plan of action based on client requirement
Step 5: Follow up services (if required)- Verification of results and compliance after installation of mitigation system by preferred vendors.
Identifying the source of the sound is the first step in the process of noise mitigation.The most common significant noise sources in industries include Compressors, Turbines, Boilers and steam recovery systems, Turbo gas chimneys, Air coolers, Pumps and Electrical motors etc.
Modelling is usually developed through proper predictive noise propagation software.The modelling output will be noise level contours depicting the noise levels within the plant and surroundings of the plant boundary. As per client’s request each scenario would be taken separately and assessed for the contribution level based on the contribution to the free-field environment or open atmosphere conditions.
The report shall include vendor confirmed data on the equipment and also include the summary of the completed design stage, specified limits, supplier’s noise data, and noise control measures adopted, restricted area and outstanding areas if applicable.
After environmental noise studies are completed and presented, a wide range of design and mitigation options are available. Solutions are customized to each individual project.There are many different noise mitigation systems to be considered. iFluids works carefully with client teams to determine the optimum, cost-effective solution for each project. Ourfollow-up services include post-installation testing to verify noise mitigation results and code compliance as necessary.
Inputs required from client:
- General Plot plan – in DXF format or AutoCAD Format
- Buildings dimensions with elevation
- Equipment list – preferably in excel with size
- Vendor specifications for significant noise generating equipment
- Technical drawings of the equipment (general arrangement or assembly)
- Type of Operation of noise sources (if continuous or intermittent)
- Mechanical Datasheet
- Vendor Noise Data
- Metrological Data
- Existing Noise report data (if available)
- Noise level measurement at pre agreed time intervals and locations on plant boundary.
- Final Report including iso-noise contours (isopleths) on the Plot Plan showing the predicted noise levels at predefined time intervals andelevations above ground level.
