Product Introduction

Using the AWA6218Y mobile environmental noise automatic monitoring device (including the AWA6228+multifunctional sound level meter) and airport noise analysis software, it becomes a measurement system for aircraft noise around the airport. Complies with the GB9661-88 standard for measuring aircraft noise around airports. AWA6228+requires an SD card to continuously record and store changes in noise over time. If equipped with 1/3 octave band analysis software (S6228+-00303), the aircraft noise around the airport can be measured using precision methods. While conducting real-time 1/3 octave frequency spectrum analysis on noise, one or several misclassified events can also be cancelled based on the flight schedule. After cancellation, the weighted equivalent continuous perceived noise level LWECPN for the entire day can be recalculated. The evaluation software can read in the analysis results and measurement point information (longitude, latitude, etc.) of the analysis software, or manually input the analysis results and measurement point coordinates by the user. The software uses the binary interpolation method to draw noise contour maps based on the read or input data, and there are multiple map layers that can be inserted by the user into the map.

Product Features

There is basically no need for monitoring personnel to operate the instruments on site, which reduces the workload;

The instrument automatically records all noise within 24 hours without missing any flight events;

Automatically calculate LWECPN and generate reports after reading data into the computer;

● Can achieve precise measurement with higher measurement accuracy;

The evaluation software can estimate the data of other measurement points based on a small number of measurement points, especially the data of locations where point placement is not possible, and draw a noise contour map.
