Purpose and Preliminary Use: This free decibel meter application is provided solely as a preliminary noise monitoring tool for data logging and documentation. Its primary purpose is to help users establish that a noise incident or violation may have occurred, collect preliminary evidence, and maintain records of noise disturbances over time to support formal complaints. The data collected can serve as supporting evidence to demonstrate noise pollution, as recognized under the Environment Protection Act, 1986, and the Indian Evidence Act. Consistent documentation with date, time, and location, along with supporting video and photo evidence, is the recommended protocol.
Legal Limitations: Crucially, the readings from this application are not admissible as primary legal evidence in Indian courts or regulatory proceedings. For measurements to be legally valid for enforcement and compliance under the Noise Pollution (Regulation and Control) Rules, 2000, they must be: conducted using pre-calibrated and certified Class 1 or Class 2 Sound Level Meters conforming to IEC 61672 standards; performed by authorized personnel (such as State Pollution Control Board/SPCB representatives); and documented strictly according to CPCB protocols with traceable calibration certificates. This application, therefore, is a tool to support your case, but it cannot replace official certified monitoring.
Registration and Privacy: Access to the application requires registration and verification using a 10-digit mobile number, which is a process implemented to ensure responsible use and user accountability. Regarding privacy, we do not collect, store, or process any of your data. All measurements, recordings, and data logs are processed and stored entirely on your device, remaining completely under your control. Your mobile number is used exclusively for login authentication and verification purposes.
Disclaimers and Responsibilities: The application is provided "as is" without warranties. Its measurement accuracy may vary significantly based on device specifications, microphone quality, and environmental conditions. Users are responsible for using the application legally and ethically, ensuring all recordings comply with privacy laws, and not using the data for harassment or malicious purposes. By using this application, you explicitly acknowledge these legal limitations and agree to use it only for preliminary monitoring and complaint documentation. For official, legally binding measurements, you must contact your State Pollution Control Board.
