Noise Consultant Service

Understanding the noise profile of your industrial plant or commercial facility is important not only from a regulatory perspective but also for solving complex noise issues. Excessive noise can negatively affect employee health, communication, and morale if left unattended. Our task is to bring an acoustic engineer, when necessary, into the project scope to perform detailed analyses that establish the noise goals applicable to your plant/facility.

Noise Mitigation Consultation

To find the best and most cost-effective noise attenuation approach, we’ll perform a qualitative and quantitative analysis of the problem. When dealing with a complex issue, we reduce it to source-path-receiver relations. This simplification allows for an accurate ranking of the problems regarding their contribution to the overall noise levels. Typical tasks in a noise consultation include:

Identify the various sources of noise and measure sound pressure levels
Map noise data at various locations of the facility/ equipment for visual presentations
Customize solutions for the site with target noise levels, cost, and aesthetics in mind
Ensure compliance with workplace safety standards and building codes

Occupational Noise Measurement

The first step in noise mitigation is to measure the noise levels of the equipment and the levels the workers are exposed to at the facility. Indicators of potentially hazardous noise include speaking loudly to someone one meter away, hearing a ringing noise after work, etc. Occupational noise measurement typically involves measuring the sound pressure level with a sound level meter (SLM), integrating a sound level meter (ISLM), etc.

Noise Source Identification and Control

Noise source identification methods are used to identify and rank the most critical sub-sources of noise based on sound power, position, and frequency. The ranking is used to choose options that will most effectively control the noise.

Noise Modeling of Facilities

Noise modeling is essential in the noise attenuation process for industrial facilities with many noise sources. A combination of state-of-the-art computing and modeling software helps to visualize noise propagation points.

Source-Path-Receiver Analysis

Lowering the noise in work environments can be a complex task. The source-path-receiver approach is to break noise into three parts and apply suitable solutions for each if needed. For instance, installing fan or blower silencers along the noise path is a typical and economical noise control option.

OSHA Noise Exposure Measurement

The General Duty Clause of the OSHA act requires employers to provide a workplace free from recognized hazards that cause/are likely to cause serious physical harm or death. OSHA mandates a hearing conservation program for noise exposure when the noise is 85 dB @ 3 feet or greater. Similarly, the Mine Safety and Health Administration (MSHA), National Institute for Occupational Safety and Health (NIOSH), and Environmental Protection Agency (EPA) provide standards and guidance for worker protection.

Noise Attenuation Equipment

When the noise source (s) are identified, SysTech will recommend steps to alleviate the issue (s). These will include additional field evaluation, discussions with plant personnel, and specific attenuation equipment selection. An acoustic engineer will be called onto the project to finalize subsequent attenuation designs if a more in-depth analysis is required. There are solutions to your noise issues, whether silencers, noise wraps, or custom enclosures. Call SysTech for a noise attenuation solution.
