Under a acoustic trauma (acoustic trauma ) is understood the damage of the ear by sound.
Acute acoustic trauma
Acute acoustic trauma or acute acoustic trauma is the damage to the hearing organ caused by a single acoustic event.
- Pop trauma
- A very short sound exposure (<3 ms ) with extremely high sound pressure (shots, firecrackers) leads to damage to the organ of Corti . One speaks of a pop trauma when only the inner ear is damaged, but the eardrum and middle ear ( ossicles ) remain unharmed.
- Explosion trauma (of the ear)
- One speaks of an explosion trauma of the ear when an acute sound effect causes an injury to the eardrum and possibly the middle ear. Damage to the inner ear can also occur. The duration of the sound event is> 3 ms.
- Acute noise trauma
- When exposed to very high sound levels (140 dB or more), hearing loss or deafness can occur within minutes . The cause here is an injury to the hair cells in the cochlea. Hearing can take up to a few weeks to regenerate from an acute noise trauma; effective treatment methods are not yet available.
- Acoustic accident
- The meeting of an unusually stressed cervical spine (while working overhead or the like) with a sound level that otherwise leads to a hearing impairment only after years of exposure (over 85 dB) can cause a sudden, one-sided hearing impairment.
- Acoustic shock
- The physical and psychological consequences of a sudden and unexpected loud sound event over the telephone, headset or similar are referred to as acoustic shock . Causes can be misdirected fax signals, errors in the Internet transmission, errors in the headset and the like, particularly affected are employees of call centers. The expression is not yet very widespread in German-language literature. There are also no known adequate studies on this syndrome. In the ENT medical assessment of patients, the acoustic shock is not to be regarded as an adequate accident event. The acoustic shock is not identical to a pop trauma or acute noise trauma, hearing loss is usually not associated with it, and the triggering sound levels are usually below those of a pop trauma or acute noise trauma. Patients complain of a feeling of fullness in the ear, numbness or burning sensation in the affected ear and / or the side of the face and neck, noises in the ears, dizziness and nausea are also possible. Headaches and anxiety (especially before resuming work with a headset and the like) are also given.
Chronic acoustic trauma
Chronic acoustic trauma is synonymous with noise-induced hearing loss . Chronic acoustic trauma or chronic acoustic trauma means damage to the hearing organ caused by chronic, i.e. H. Long-term exposure to noise (over 85 dB). A noise-induced hearing loss that is acquired at work is a legally recognized occupational disease .
Treatment of acoustic trauma
In order to have the best possible chance of recovery in the event of an acoustic trauma, treatment should be started as soon as possible. In addition to classic treatment options such as taking cortisone or other drugs, studies have shown that treatment with hyperbaric oxygen (HBO) also promises success. Here, breathing in medically pure oxygen in the pressure chamber can lead to a regeneration of damaged sensory cells, as these are better supplied with oxygen.
