Noise-induced hearing loss affects adults and kids alike. This condition develops when damage occurs to the delicate hair cells in the inner ear due to exposure to loud sounds or noises. Get more ...
Acoustic trauma can occur from a single, loud noise exposure or loud noise over a period of time. One sign of acoustic trauma is ringing in the ears and muffled hearing after a loud sound exposure.
Traumatic noise exposure can happen at work (e.g., loud machinery), at play (e.g., loud sporting events, concerts, recreational activities), and/or by accident (e.g., a backfiring engine.) Noise induced hearing loss is sometimes unilateral and typically causes patients to lose hearing around the frequency of the triggering sound trauma.
Occupational noise exposure is the main risk factor for work-related hearing loss. One study examined hearing test results obtained between 2000 and 2008 for workers ages 18–65 who had a higher occupational noise exposure than the average worker. [153] Of the sample taken, 18% of the workers had hearing loss.
Acoustic trauma is an injury to the inner ear that's often caused by exposure to a high-decibel noise. This injury can occur after exposure to a single, loud noise or from exposure to noises at significant decibels over a longer period of time. [medical citation needed] Many cases have included a period of reduced hearing after exposure to loud ...
In many cases, worsening, high-pitched tinnitus and hearing loss are linked to damage from noise exposure over time and can hit suddenly or worsen gradually, per a 2016 study in Noise & Health.
Acoustic shock is the set of symptoms a person may experience after hearing an unexpected, loud sound. The loud sound, called an acoustic incident, can be caused by feedback oscillation, fax tones, or signalling tones. Telemarketers and call centre employees are thought to be most at risk. [1]
However, if the noise is loud enough or happens frequently enough, the damage can be permanent. This is called noise-induced hearing loss (NIHL), and it happens when the tiny hair cells in your ...
