Deafening works in a similar way to Dazzling, but is based on the Loudness of an event in place of Illumination. Like Illumination, Loudness drops off by 1 point per 5 metres. If Loudness exceeds 10 you start taking Deafening Penalties, at -10 you are temporarily deaf. These penalties fade at the same rate as Dazzling. Covering your ears to defend against loud noises works in an analogous fashion to covering your eyes versus flashes. Likewise a constant level of Loudness beyond 5 provides a Noise Penalty that quickly fades when the noise ceases.
