Loud Music and Tinnitus




If your tinnitus has been caused by exposure to loud noise, for example from a rock concert or night club, then it is likely that the tinnitus will go within a day or so. However, although it is temporary, this should act as a warning that you have exposed you ears to a higher level of noise than they are comfortable with. If you let this happen frequently then it is possible that the tinnitus or any dullness of hearing, or both, may become permanent.
You should wear ear protection to protect your ears from damage when you are exposed to loud noise either at work or during leisure activities.

Mechanisms of subjective tinnitus

The inner ear contains thousands of minute hairs which vibrate in response to sound waves and cells which convert neural signals back into acoustical vibrations. The sensing cells are connected with the vibratory cells through a neural feedback loop, whose gain is regulated by the brain. This loop is normally adjusted just below onset of self-oscillation, which gains the ear spectacular sensitivity and selectivity. If something changes, it's easy for the delicate adjustment to cross the barrier of oscillation and tinnitus results. This can actually be measured by a very sensitive microphone outside the ear.

One of the possible mechanisms of how things can change in the ear is damage to the receptor cells. Although receptor cells can be regenerated from the adjacent supporting Deiters cells after injury in birds, reptiles, and amphibians, in mammals it is believed that they can be produced only during embryogenesis. Although mammalian Deiters cells reproduce and position themselves appropriately for regeneration, they have not been observed to transdifferentiate into receptor cells except in tissue culture experiments.[15][16] Therefore, if these hairs become damaged, through prolonged exposure to excessive decibel levels, for instance, then deafness to certain frequencies occurs. In tinnitus, they may falsely relay information at a certain frequency that an externally audible sound is present, when it is not.
The mechanisms of subjective tinnitus are often obscure.

While it is not surprising that direct trauma to the inner ear can cause tinnitus, other apparent causes (e.g., TMJ and dental disorders) are difficult to explain. Recent research has proposed that there are two distinct categories of subjective tinnitus: otic tinnitus, caused by disorders of the inner ear or the acoustic nerve, and somatic tinnitus, caused by disorders outside the ear and nerve but still within the head or neck. It is further hypothesized that somatic tinnitus may be due to "central crosstalk" within the brain, as certain head and neck nerves enter the brain near regions known to be involved in hearing.

While most discussions of tinnitus tend to stress physical mechanisms, there is strong evidence that the level of an individual's awareness of their tinnitus can be stress-related, and so should be addressed by improving the state of the nervous system generally, using gradual, unobtrusive, long-term treatments.

Is it true?

Is it true that stress can make tinnitus worse?
Stress and tinnitus are strongly linked. In some cases, such as bereavement, stress can actually causes tinnitus. However, generally it may exacerbate it. Stress caused from worrying about tinnitus can increase muscle tension, anxiety and irritability, making your tinnitus worse and leading to an increase in stress, which becomes a vicious circle.
Research has shown that the more you can relax, the easier it is to manage tinnitus. And relaxing doesn't need to be difficult or costly. If you take a walk or have a warm bath it can help.

Objective tinnitus

In a minority of cases, a clinician can perceive an actual sound (e.g., a bruit) emanating from the patient's ears. This is called objective tinnitus. Objective tinnitus can arise from muscle spasms that cause clicks or crackling around the middle ear. Some people experience a sound that beats in time with the pulse (pulsatile tinnitus). Pulsatile tinnitus is usually objective in nature, resulting from altered blood flow or increased blood turbulence near the ear (such as from atherosclerosis or venous hum ,but it can also arise as a subjective phenomenon from an increased awareness of blood flow in the ear. Rarely, pulsatile tinnitus may be a symptom of potentially life-threatening conditions such as carotid artery aneurysm or dissection.

Ear loss

Temporary hearing loss can happen after you've been exposed to loud noise for 15 minutes or less. If you have temporary hearing loss, you won't be able to hear as well as you normally do for a while. You may also have tinnitus ,which is a medical term for ringing in the ears. Your ears can feel "full," too. Luckily, these symptoms usually go away and your hearing is likely to return to normal.

If someone is exposed to loud noise over a long period of time, like every day, permanent hearing loss can occur. This means the person's hearing won't ever be as good as it once was. That's why construction workers and factory workers need to wear ear protection. Lawn mowers and power tools, like chain saws, can also be loud enough to affect a person's ability to hear high-pitched noises.

This kind of noise also can cause a person to have tinnitus all the time.
Listening to extremely loud music a lot can cause the same kind of damage, especially if headphones are used. Some famous musicians have lost hearing and developed tinnitus - a real problem for someone who needs to hear to make and enjoy music.
But you can help keep your hearing in tip-top shape.

Protect your ears by wearing ear protection when you're using machinery, like in metal shop at school. Also remember to turn down the volume, especially when you are wearing headphones or in the car. You also might want to give your ears a rest once in a while if you like wearing headphones.

And if you're going to a concert, where you know the music is going to be loud, consider wearing earplugs to protect your ears from the boom, boom, boom! Take these steps now and you won't be saying "What?" later on.

Fountains



The sound of running water can be very soothing and can help to mask tinnitus. Try installing an indoor fountain in your home. These are available from garden centres or general stores such as Argos and cost around £25.
