Basics of Noise and Vibration Engineering

Course Description

Basics of noise and vibration engineering is an interaction-intensive introductory course in noise and vibration engineering and provides the first step towards understanding the fundamentals of the subject, detecting the problems related to noise and vibration engineering and devising a practical approach towards solving them. The focus of the training is on imparting a right mix of theoretical and practical knowledge of the subject and includes multiple demonstration sessions on the various topics covered in the classroom. The participants are also exposed to a variety of real world problems along with the proper approaches, standards and techniques involved in diagnosing and tackling them. The course is non-vendor biased and is designed independent of a particular manufacturer’s instruments and software. The voluminous participation in our previous programs and the eclectic set of industries we have had the professionals attending from speak utmost of the quality of our program.

Who Should Attend

This course does not demand any pre-requisite knowledge about the noise and vibration analysis and starts from the very basic, thereby making it ideal for people with little or no background in this subject. The training is most beneficial for the people in the role of engineer/manager/team-lead in one or more of the following functional categories:

  • Maintenance.
  • R&D/ Product Design.
  • Quality Assurance.
  • Testing/ CAE/ Simulation.
  • Process Engineering.
  • Installation and Commissioning.
  • Application/ Support.
  • Students & Faculty.
  • Qualification for various norms and standards.

Why Should You Attend

You should take this course if you desire to gain awareness of the problems and the testing & analysis techniques in the domain of noise and vibration engineering. Apart from this, the training will also put in a better position to devise and plan your strategy for tackling such issues at your facility. In addition to gaining an overview of the subject and becoming acquainted with numerous standards the industry follows, you will also realize the importance of the experimental noise and vibration in quality assurance, validation of product design and various other applications/situations.
