Environmental Noise

Time domain noise source location

The combination of three particle velocity sensors makes possible the location of impulsive noise sources in a very large area range. This system is specially designed for Harbours, dry ports and industrial areas where goods are handled ,carried  and stored so very heavy machinery and containers are displaced and dropped causing severe noise problems to the area inhabitants.

Each measuring station is autonomously driven , continiusly monitoring 360 degrees,once an station is noise triggered and the impulsive event is detected, the event is time domain analyzed and localized. The information is sent via GSM connection to a central server where the data from all the measuring stations is collected. This information is related to a reference coordinate system and then the exact location of the noise emitter can be noticed and fined.

The control network is completely scalable being able to increase the number of control stations by a  GPS synchronization system which allows to correlate the results from every station. As he system grows it becomes a more reliable control network, with a wider coverage range, several station location and back-up stations so big industrial areas can be controlled and centralized  by a single acoustic system as easily as small load and unload areas such as supermarket delivery entrance.

Annoyance can be included and correlated with the measured data in order to directly relate it to it's cause. Also a camera can be added to the system, triggered and pointed by the detected noise event.

 

Application features:

  • Time domain impulse analysis
  • Particle velocity based system
  • Scalable system, from 1 to several GPS synchronized control stations
