| Abstract | The use of Remotely Piloted Aircraft Systems (RPAS) has experienced a significant increase in recent years. These systems are now being utilized for new purposes, such as package delivery, medical supply transportation, and urban videography. This has resulted in an uptick in their use, particularly in densely populated urban areas. However, for the use of RPAS to be sustainable, it is essential to maintain sound levels that are in line with or below the usual background levels of the region. It is worth noting that these levels can differ significantly between large city centers, suburbs, and rural areas. Studies funded by Transport Canada have revealed that noise pollution generated by RPAS may impede public acceptance, indicating that future noise regulations may need to consider social acceptability, taking into account not only safe noise levels, but also the annoyance and perception of noise by humans. |
