NVH PDF

A technical documentation that delves into the challenges of reducing noise, vibration, and harshness (NVH) in modern automotive engineering. The document explains sound theory, the propagation of sound, and methods to measure sound levels in vehicles. It discusses the sources of vehicle noise, including mechanical engine noise and tyre noise, and the role of turbocharging in noise reduction. The inclusion of diagrams and charts helps in understanding the relationship between various noise sources and their impact on vehicle performance.
