Active Vibration Control Methods: Effective Tools in Noise Reduction

For a workplace to be conducive to a productive and convenient surrounding, it must be free from any disturbance and nuisance. However, since machines and heavy equipment such as fan surround most of the office spaces in a building, air-conditioned and other equipment, it is unavoidable to experience distraction caused by vibration from equipment and machines. Hence, the workspace will be exposed to unnecessary sound or noise that may affect the productivity of the employees.

According to studies, employee’s productivity is mainly accounted to how conducive and appropriate their working environment is. As such, as a property manager or a business owner, you definitely want to give the best to your employees to allow them to function well and accordingly with their job. As such, any distraction, noise or vibration must be eliminated to achieve wellness and order. But the question is – how do you reduce any nuisance caused by your equipment and machines? This is when anti vibration methods come into the picture. If you are not yet aware about what a vibration control is, you are in the right place. This article will give you an overview of how vibration control methods work and it will walk you through the importance of utilizing it accordingly.

Through the continuous advancement of technology, new devices and tools are being created, developed and introduced to the market that help different organizations, businesses, and people to have a convenient and hassle free environment. One of those is the active vibration controller. Basically, a vibration isolator is a device or tool designed to eliminate and control the noise and vibration that comes from any machines, objects or equipment. With this tool, workers can now experience a working environment that is conducive to productivity and healthy work place. Furthermore, there are different factors that you should consider before selecting the right vibrator isolator for your workspace. These factors will be explained as you read on this article. These factors will help you determine the design and features of vibration isolator that you should purchase. These factors also serve as your basis in drafting the overall layout of your equipment and machineries so an expert can easily look after the internal and external components and aspects of your workstation, machines, and materials that indicate the type of loadings that you should also take into consideration when looking for the right vibration isolator.

Active vibration control has been promoted and utilized as one of the most efficient methods to eliminate unnecessary vibrations coming from wide variety of machines, equipment and systems. Efficient functions and usage of every vibration control method is relevant to the proper selection of dynamics of the unit of selection and the accuracy of the design. Active vibration control methods have been carefully evaluated and assessed by experts in the previous years of studies. Moreover, the usage of these methods has demonstrated efficiency and positive feedback from its users. So if you are looking for an effective method to reduce vibration in your workplace, you must always go for a method or controller that have been reliably used by a lot of organizations and individuals. With this, you will be able to guarantee the quality and efficiency of your tools. Hence, you can provide a safe, healthy, and conducive to learning environment for your people. Moreover, noise reduction using active vibration control methods have been highly recommended by experts. In this case, you can ensure that you are investing your money in the right tool. After all, your workers safety and productivity should always be given high importance.

Now that you are aware about the importance of active vibration control method, it is now time to know what are the necessary things that you need to consider when choosing the right tool or method of noise reduction. According to expert, the main factor or point that one must take into consideration is to understand and know the issue very carefully. Identifying exactly the issues or problems will easily help you understand what design, features and type of active vibration method you should use. Technically, when the system id studied and analyzed completely, the source of the disturbance is commonly known and the system of the model is being extracted. Consequently, the engineer has to locate the accurate and appropriate place that an actuator can be set. Moreover, being able to obtain feedback from the vibrating structure is essential in designing the active vibration controller. Thus, the type of the accessible sensors and actuators must be clearly specified and identified. The accuracy of the solution relies on how accurate and specific the identification of the problem is. As such, knowing and understanding the issues should be one of the highest considerations when it comes to getting an active vibration controller.

To arm you with the different methods of active vibration control, this article will also discuss such information with you. Some of the most common and effective methods are integral-based controllers, sliding mode control and nonlinear method, positive position feedback or PPF and vibration control in MEMS systems.

Integral based controllers

This method is considered as one of the most efficient methods for vibration control. These types of methods have a first order integrator which is responsible in increasing the damping of the system when they are used in a closed-loop form.

Sliding mode control

This method is considered as adaptive in nature as it has been utilized in energy harvesting.

Positive position feedback

This type of control method is being used in space structures vibration control.

MEMS or Micro Electro Mechanical SYSTEMS

This type of method utilizes micro-gyroscopes that provide a low cost inertial measurement of rotation rate by sensing the Coriolis force.

Apart from the mentioned tools and methods, there are other more methods that experts use in controlling vibration. However, the above mentioned are usually the most popular and the most used methods because of their efficiency and positive feedback and results from their users.

As the convenience and productivity of workers should always be the priority of businesses, using active vibration control methods is the best way to promote a conducive, healthy and safe working environment for workers. These methods are designed specifically for different features and approaches but basically, they have the same purpose and function – to eliminate and control the unnecessary noise and vibration of nay objects, machines and equipment in the workplace. Hence, workers can feel comfortable and secured when they are working that will result to high productivity rate that will allow the business to achieve its goals and objectives.

In this light, it is very much fair to say that noise reduction machines are more than just working tools, they are necessity. In a business setting where productivity and convenience of workers are very crucial in the overall success of the business in its operation and production, it is necessary to deploy all the necessary equipment that would aid in reducing and hindrance of productivity. As such, this is when noise reduction and power comes into the picture. Since they are very crucial in all the property and building setting, you must be able to choose the right noise reduction tool that will work best for your business.
