NIHL can be either permanent or temporary, called a threshold shift. Unsafe levels of noise can be as little as 70 dB (about twice as loud as normal conversation) if there is prolonged (24-hour) or continuous exposure. 125 dB (a loud rock concert is ~120 dB) is the pain level; sounds above this level cause instant and permanent ear damage.
The damage can become permanent (permanent threshold shift, PTS) if sufficient recovery time is not allowed before continued sound exposure. [1] When the hearing loss is rooted from a traumatic occurrence, it may be classified as noise-induced hearing loss, or NIHL. There are two main types of auditory fatigue, short-term and long-term. [2]
A TTS will resolve with time, while the time frame for hearing recovery is unique in every case, any SNHL that persists beyond eight weeks after injury is most likely permanent and should be considered PTS.

Noise damage is cumulative; all sources of damage must be considered to assess risk. In the US, 12.5% of children aged 6–19 years have permanent hearing damage from excessive noise exposure. [55] The World Health Organization estimates that half of those between 12 and 35 are at risk from using personal audio devices that are too loud. [11]
However, many exposure scenarios can be considered a risk of hearing disorders, and many individuals are negatively impacted by tinnitus and other hearing problems. [49] While some population studies have shown that the risk for hearing loss increases as music exposure increases, [ 49 ] other studies found little to no correlation between the ...
Noise from traffic, in particular, is considered by the World Health Organization to be one of the worst environmental stressors for humans, second only to air pollution. [2] Elevated workplace or environmental noise can cause hearing impairment, tinnitus, hypertension, ischemic heart disease, annoyance, and sleep disturbance.
Various ototoxic effects are manifested by using antimalarial drugs, with dizziness being one of the most common one. Other effects include vestibular symptoms, hearing loss and tinnitus, which can appear to be both temporary or permanent. [25] Nonetheless, the underlying mechanisms of antimalarial-induced ototoxicity are still poorly understood.
