A Review on Acoustical Properties Measurement Methods and A Proposed Novel Method for Acoustical Characterization of Laminated Glass used in Automotive Applications
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2017, Vol 7, Issue 4
Abstract
Many-a-time, deviation of attention of driver due to excessive noise is among the major factors responsible for accidents, and 54.3 dB of the sound between 500 to 5000 Hz is the high noise transmitted to the driver among all the components of the car [1]. Thus, there is a strong requirement for inclusion of acoustical measures for the laminated glass (LG) in IS 2553. The present work includes, a brief review on literature reported on acoustical properties measurement using traditional ASTM E1050-98 (sound absorption testing using impedance tube) and ASTM C423 (sound absorption testing using scale rooms) and acoustical measurements that are reported in literature for biological and other applications. A novel method is also proposed for the acoustical property measurement. The Finite element (FE) simulation for the acoustical property measurement of polyvinyl butyric (PVB) LG (material used for windshield) sample is also performed based on the proposed experimental method.
