The Adaptation of Waste Date Palm Fibers for Sound Absorbing Purposes
Main Article Content
Abstract
In this study, an experimental procedure is developed in order to elaborate an acoustic absorber based on date palm fibers. This kind of material has a double interest: The first is due to its great importance in environment protection by recycling wastes; the second is the fact that these materials are used in the treatment of a second environmental problem which is the noise pollution by reducing it. In this work, wastes from the date palm were used to manufacture an acoustic absorber. In fact, agriculture wastes are increasingly used in the acoustic field. In this work, wastes from date palm were used to manufacture acoustic absorbers. To achieve this goal, date palm waste is acoustically evaluated by an experimental characterization based on measuring the acoustic absorption coefficient of the studied material in the frequency band [0-4000 Hz] using the Kundt tube. The obtained results are encouraging with acoustic absorbent coefficient reaching 0.9 in some frequencies.

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.
