The SV 307A is an innovative noise station dedicated to the continuous monitoring of noise levels through the integration of a class 1 sound level meter with 4G and GPS modems. Its waterproof casing can be removed to have access to the user interface with a color screen and an operating keyboard. The SV 307A is equipped with a patented MEMS microphone with a guarantee of life and the measurement data are stored in a removable microSD card, as well as being sent via its integrated 4G modem to a dedicated server on the cloud using the SvanNET platform. It also counts with the verification of the system using an internal noise source at 90 dBA and 1 kHz, which allows you to always have information on the operating status of the microphone. Other variables can be additionally integrated into the system, such as weather conditions of wind speed, wind direction, rain, humidity, among others. Including if you can have PM2.5 or PM10 particulate material monitoring together with the noise data through external sensors. The SV 307A is an ideal option for measuring environmental noise, providing all the parameters of environmental monitoring for the control, evaluation, and modeling of noise. It is ideal for environmental measurements, monitoring in constructions, preparation of noise maps, industrial noise monitoring, assessment of environmental impacts, compliance with environmental management plans, noise control in neighboring areas, among others.
