Abstract
Ocean sound is an Essential Ocean variable. As such, it requires detailed study and monitoring. Within this framework, this study comprises the process of development of an optimized Matlab software package for the analysis and characterization of underwater sound recordings from wind farms. This software package is based on a Matlab script produced by one of the authors. This script was analyzed, and the following modifications were done: 1- The one-third-octave band filters were replaced by stable filters that meet the IEC 61260-1 standard. 2- The low band and band pass filters were replaced by a single bandpass filter 3- Five additional metrics were included, in such a way that the script generates the following metrics: SPL (Sound Pressure Level), Leq (Equivalent Level), L1, Ls, L10, L50, L90, L 95, and Lpeak (Peak level). 4- The computational load of each line of code was measured and the software modified to increase the speed of execution. 5- The results are saved in the hdf5 file format. As a result, a Matlab software package was created that generates the desired metrics, performs faster than the original script, and saves the results in a standard file format.
