Characterization of the Automotive Interior Cabin Noise: Interior Trim Acoustic Materials - Research Proposal Example

This therefore means that the automotive industry has had to focus on the redesigning the interior of this personal cars to make the cars as quiet as possible. The automotive industry has been compelled to enhance their interior trim products with better designs due to eco-friendly factors such as whether these products are recyclable, the fact that the noise and vibrating levels have the possibility of resulting to serious health issues and price of products. However, there is still a lot of research that need to be done in order to get a more profound understanding of the consequences of the interior trim design on the noise and vibrating levels.

Once this improved and refined trim designs and concepts are recommended for the automotive industry, this need to enhance their interior trim products with better designs will become even more obligatory. Hence, this research paper is anticipated to deliver a practicable process which can estimate and optimize the interior cabin noise level for dissimilar interior trims and seating arrangement. In carrying out this research we first have to understand the effects of vehicle interior trims in minimizing interior cabin noise.

In doing so, we will begin by establishing the noise characteristics. In establishing the noise characteristics of interior design, I will peg my research on a paper published by Jha and Priede which investigated the simplest mechanism of understanding how noise is generated in a car. This noise is majorly caused by the vibration of the cabin walls. While this research was carried out over 30 years ago the findings from this research are still applicable with the design and features of an ordinary modern day vehicle.

Jha and Priede carried out experiments of internal noise spectra of a number of vehicles. The internal noise spectra of the vehicles were also done at contrasting speeds. The internal noise spectra was seen
