Implications of Smartphone Technology in Environmental Noise Monitoring in Indian Perspectives

Abstract

The paper extensively reviews the recent studies conducted on environmental noise monitoring and control using smartphone applications. The methodologies and procedures adapted by several researchers utilizing smartphone technology has been summarized. The study also discusses the various methods of calibration and the calibration factor observed for smartphone when compared to sound standard. This study concludes that the smartphone applications is an easy, cheap and convenient technology as compared to the conventional technology provided the calibration of smart phone microphone is undertaken with reference to sound standard and free-field microphone for environmental noise measurements.
