Understanding the importance of Noise, Vibrations & Harshness related sources and mandatory requirements in Vehicular applications. Parameters affecting design criteria, construction & architecture, as well as operational systems for reduction of NVH. Subjectively evaluate vehicle performance characteristics for functional requirements including mandatory - safety parameters. In order to better prepare today’s automotive engineer for this course, to help in understanding fundamental principles and automotive system applications, along with associated improvements implemented in different models of vehicles.
Course Outcome
1. Students will become familiar with the basic terminologies of Noise, Vibration & Harshness – NVH, which is a major focus for high end luxury vehicles manufacturers, in the current times. 2. Students will acquire Comprehensive, theory based understanding of natural and physical sciences along with engineering fundamentals related to Sources of Vibration and Noise applicable to the automobile engineering discipline and possibility of modifications and improvements. 3. Student will understand Application of engineering techniques, tools, for measurement methods in order to learn to control and solve complex Vehicle vibrations behavior /as well as performance problems. 4. Student will learn Application of systematic engineering synthesis and design processes for eliminating or reducing the Vibration, Noise to reduce irritation to occupants and achieve improvement in perception of ride comfort.

Active Learning
Preparation of power-point slides, which include videos, animations, pictures, graphics for better understanding theory and practical work – The faculty will allocate chapters/ parts of chapters to groups of students so that the entire syllabus to be covered. The power-point slides should be put up on the web-site of the College/ Institute, along with the names of the students of the group, the name of the faculty, Department and College on the first slide. The best three works should submit to GTU.
