The simple answer is YES - a single very loud noise can cause temporary and even permanent hearing loss.
According to the Canadian Academy of Audiology:
"...there can be a sudden permanent hearing loss if there is exposure to a brief but very intense sound."
More from the Canadian Academy of Audiology on noise induced hearing loss:
There are three types of noise-related hearing loss. Temporary damage is done slowly and will often come back after a rest from the noise. Often people who have attended a loud rock concert have experienced this type of hearing loss.
Temporary hearing loss can progress to a permanent loss over time if the noise/music is loud enough and the exposure time is long enough. The damage sustained is cumulative, so each new exposure can add to hearing loss.
Finally, there can be a sudden permanent hearing loss if there is exposure to a brief but very intense sound.
