Noise Monitoring

Observer supports a better environment by supporting environmental noise measurement practices. Observer Noise consists of 3 modules: 1. Noise Measurement Devices: It stores the environmental noise data by measuring in decibels. Observer can measure environmental noise by two different device classes:

Class 2 Device: Measures in the range of 1000 ± 125 Hz. Its accuracy range is ±3 dB.
Class 1 Device: Measures from 31.5 Hz to 16000 Hz more sensitively at 8 main frequencies. Its accuracy range is ±2 dB and hence more than Type2. For more information

2. Communication Terminals: Collecting the data on-site environmental noise measurement devices, it transmits the data to the central server over GPRS connection to be stored and analyzed via reports. Furthermore it evaluates the noise data on-site and sends an alarm SMS and/or e-mail if the alarm treshold is exceeded. 3. Central Server: The data stored in he central server database can be retrieved by the users by a web browser. Alarms can be screened. Following are possible through Noise Observer:

Noise data collected from noise measurement stations are transmitted to center in decibels after being analysed by GPRS and EDGE telemetry devices.
Data can be monitored on mobile phones, main servers and internet.
When the decibel limits are exceeded, the authorized inspectors are alerted by sending SMSes to their mobile phones.
Through reporting tools the historical noise data can be evaluated statistically and success graphic can be viewed in desired time intervals.
The location of stations where the system is set-up can be changed.
The system brought environmental efforts to a higher dimension by utilizing recyclable energy resources like solar energy.
