Main Article Content
The importance of acoustic comfort has grown in the past few years in case of passenger cars, since regarding consumer side, the quality of the vehicle is strongly influenced by that criterion. In this paper the sound pressure level of passenger vehicle was investigated. A B-segment estate car was chosen for the acoustic experiments as sample vehicle. Input data were varied in three levels containing qualitative (working condition of the vehicle) and quantitative (excitation from the outer environment) ones as well. Pink noise was chosen as measurement signal and the values of the generated equivalent continuous sound pressure level were registered in the cabin in case of each possible combination of the levels of the input variables. Based on the measured data, a second order empirical model was constructed by help of response surface methodology (RSM). The accuracy and the conformity of the equation were investigated by help of the residuals. The applicability of the formula was verified by further confirming measurements. Investigations revealed that the residuals follow Gaussian distribution in both cases, what is more, have small-scaled standard deviation. As a consequence, the presented formula is proper for calculating the sound pressure level of the vehicle interior with an adequate accuracy within the range of the parameters examined.
Journal author rights
In order for Romanian Journal of Acoustics and Vibration to publish and disseminate research articles, we need publishing rights. This is determined by a publishing agreement between the author and Romanian Journal of Acoustics and Vibration. This agreement deals with the transfer or license of the copyright to Romanian Journal of Acoustics and Vibration and authors retain significant rights to use and share their own published articles. Romanian Journal of Acoustics and Vibration supports the need for authors to share, disseminate and maximize the impact of their research and these rights, in Romanian Journal of Acoustics and Vibration proprietary are defined below:
For subscription articles:
Authors transfer copyright to the publisher as part of a journal publishing agreement, but have the right to: Share their article for personal use (manuscript version); retain patent, trademark and other intellectual property rights (including research data); proper attribution and credit for the published work.
For open access articles:
Authors sign an exclusive license agreement, where authors have copyright but license exclusive rights in their article to the publisher. In this case authors have the right to: share their article in the same ways permitted to third parties under the relevant user license; retain patent, trademark and other intellectual property rights (including research data); proper attribution and credit for the published work.
Rights granted to Romanian Journal of Acoustics and Vibration
For both subscription and open access articles, published in proprietary titles, Romanian Journal of Acoustics and Vibration is granted the following rights:
- The exclusive right to publish and distribute an article, and to grant rights to others, including for commercial purposes;
- For open access articles, Romanian Journal of Acoustics and Vibration will apply the relevant third party user licence (Open access licencses) where Romanian Journal of Acoustics and Vibration publishes the article on its online platforms;
- The right to provide the article in all forms and media so the article can be used on the latest technology even after publication;
- The authority to enforce the rights in the article, on behalf of an author, against third parties, for example in the case of plagiarism or copyright infringement.
