strategic noise map shall mean a map designed for the global assessment of noise exposure in a given area due to different noise sources or for overall predictions for such an area." EU Member States are required to produce strategic noise maps in their main cities, near the main transport infrastructure and industrial sites. The main goals of ...
The pre-processing of ambient noise data refers to the filtering of the raw data before proceeding to further analysis (cross-correlation, inversion). Raw seismic data can be collected by either geophones, seismometers, or from authorized official bodies. There are also public ambient noise source maps available in recent years. [8]
The Sound Around You Project began as a soundscape research project [7] at the University of Salford, UK in 2007.The project allows people to use audio recorders to record clips or sonic postcards of around 30 seconds in length from different sound environments, or ‘soundscapes’ from a family car journey to a busy shopping centre, and to upload them to the virtual map, along with their ...
The map aims to assist city planners, elected officials, scholars, and residents to gain access to up-to-date aviation and Interstate highway noise information. [117] States and local governments typically have very specific statutes on building codes, urban planning, and roadway development. Noise laws and ordinances vary widely among ...
Noise experts and some small specialized companies have slowly developed a limited number of calculation tools, which have increased in number and become more user-friendly, covering more application cases, and adding service elements to the noise calculation tools. The noise calculation process is complex in input (gathering data, correctly ...

Sound localization technology is used in some audio and acoustics fields, such as hearing aids, surveillance [1] and navigation.Existing real-time passive sound localization systems are mainly based on the time-difference-of-arrival approach, limiting sound localization to two-dimensional space, and are not practical in noisy conditions.
In noise-limited conditions at initial detection: [33] SL − 2PL + TS − (NL − AG) = DT, where SL is the source level , PL is the propagation loss (sometimes referred to as transmission loss ), TS is the target strength , NL is the noise level , AG is the array gain of the receiving array (sometimes approximated by its directivity index ...
