Hearing loss caused by loud noises is called noise-induced hearing loss. It is more common for gradual hearing loss to occur from long-term exposure to loud noise than from a sudden loud burst of sound. Hearing loss may be temporary or permanent. Long-term exposure to loud noises can cause permanent hearing loss.
Common causes of acoustic trauma include:
- Loud music, such as live musical performances and home, auto, or portable stereo systems. Hearing loss is usually temporary but can be permanent.
- Industrial sounds, such as traffic, sirens, jet engines, power tools, chain saws, jackhammers, or hydraulic machinery.
- Physical injury to the ear. Severe injury can rupture the eardrum. Physical injury can be caused by:
- A blow to the side of the head.
- An explosive burst of sound close to the ear, such as when an air bag is set off during a motor vehicle accident.
- Rapid changes in environmental pressure, such as from underwater diving or descending in an airplane.
Most people stop hearing high-frequency sounds, such as bells and chimes, first. Later, it becomes harder to hear lower-frequency sounds, such as voices.
Because of this danger, “safe listening” is important for children and adults. Thankfully, the American Speech-Language-Hearing Association (ASHA) started a campaign called “Listen To Your Buds” to help increase awareness and to inform people of the appropriate listening levels and when to take breaks from listening to preserve hearing.
