Ensure that white noise machines are set at a safe volume and a safe distance away from a sleeping person before use.

Depending on how noise impacts someone, they may benefit from consulting with a hearing or sleep specialist. A therapist can also help teach coping mechanisms. For children exposed to frequent or loud noise, it is important to monitor for signs of hearing loss.

Listening to loud noise for a long time can overwork hair cells in the ear, which can cause these cells to die.

The hearing loss progresses as long as the exposure continues. Harmful effects might continue even after noise exposure has stopped. Damage to the inner ear or auditory neural system is generally permanent. The average person is born with about 16, hair cells within their cochlea. These cells allow your brain to detect sounds. By the time you notice hearing loss, many hair cells have been destroyed and cannot be repaired. You might not hear whispers, sound might seem muffled, or you may hear ringing in your ears.

Normal hearing usually returns within a few hours to a few days. This is because the hair cells, similar to blades of grass, will bend more if the sound is louder.

But they will become straight again after a recovery period. However, if loud noise damaged too many of the hair cells, some of them will die. Repeated exposures to loud noises will over time destroy many hair cells. This can gradually reduce your ability to understand speech in noisy places. Eventually, if hearing loss continues, it can become hard to understand speech even in quieter places.

In addition to damaging hair cells, noise can also damage the auditory nerve that carries information about sounds to your brain.
