The 2nd RUMBLE Open Workshop has been performed @ e-FORUM ACUSTICUM 2020

The RUMBLE Consortium was glad to organize the 2nd RUMBLE Open Workshop which was held in the frame of the e-FORUM ACUSTICUM 2020 with the aim to present the project's achievements regarding low sonic boom and supersonic flight. Despite the COVID-19 negative impact, especially for in-person gatherings, the event took place virtually giving the opportunity for RUMBLE to showcase its results.  

The 2nd RUMBLE Open Workshop was performed on Tuesday, 8th December, 2020 from 08:50 to 17:30 during the onlinve event 9th Forum Acusticum, organized by the European Acoustical Association (EAA) together with the French Acoustical Society (SFA). More than 1100 attendees from all over the world participated to around 100 structured sessions. 

The Purpose

The 2nd RUMBLE Open Workshop presented and discussed the final outcomes and lessons learned within RUMBLE. Furthremore, the event has set the basis to establish and promote comprehensive roadmaps for technology regarding low sonic boom and supersonic flight. In this frame the following presentations took place, the abstracts of which can be found here (column St Clair 3B). The session was also followed by a round table more than one hour long. More specifically, the following presentations have been presented in the event: 

1. Effects of atmospheric turbulence on sonic boom metrics and annoyance
