Dutch person to the rescue. Here's my translation:
Permanent Hearing Damage for Over 20 Victims of the 22 March Attacks
Antwerp - After the attacks in Brussels in 2016, 56 people were treated for hearing damage at the University Hospital Antwerp (UZA). 40 percent of them have permanent complaints such as hearing loss or tinnitus due to the explosions, UZA reports this Friday.
After the attacks at the airport, many people reported to the UZA who initially seemed unharmed, but had nausea afterwards. "56 patients presented with complaints of reduced hearing, tinnitus, a feeling of pressure and/or hypersensitivity to sounds," says Annick Gilles of the UZA. Three patients also showed perforation of the eardrum by the pressure wave from the blast.
It is striking that the majority of patients showed hearing damage to the right ear, because the first explosion took place on the right side of the terminal. The second explosion went off on the other side of the terminal while everyone approached the exit, so that the second explosion also occurred on the right side of most people.
