    Suppressors are one of the fastest growing parts of the firearms industry at the moment. And for good reason – given the right combination of host, suppressor and ammunition, shooting goes from fun to awesome. Besides that, they also just look cool. However, for many of us who have a lifetime of shooting under their belt, some form of hearing loss is a given. A suppressor in conjunction with quality ear muffs and/or plugs can reduce your exposure to damaging noises. Here’s a brief look at tinnitus, one of the more common types of hearing damage among shooters.


    From the Mayo Clinic (http://www.mayoclinic.org/diseases-conditions/tinnitus/home/ovc-20180349):

    Tinnitus (TIN-ih-tus) is the perception of noise or ringing in the ears. A common problem, tinnitus affects about 1 in 5 people. Tinnitus isn’t a condition itself — it’s a symptom of an underlying condition, such as age-related hearing loss, ear injury or a circulatory system disorder.

    Although bothersome, tinnitus usually isn’t a sign of something serious. Although it can worsen with age, for many people, tinnitus can improve with treatment. Treating an identified underlying cause sometimes helps. Other treatments reduce or mask the noise, making tinnitus less noticeable.

    Symptoms

    Tinnitus involves the annoying sensation of hearing sound when no external sound is present. Tinnitus symptoms include these types of phantom noises in your ears:

    • Ringing
    • Buzzing
    • Roaring
    • Clicking
    • Hissing

    The phantom noise may vary in pitch from a low roar to a high squeal, and you may hear it in one or both ears. In some cases, the sound can be so loud it can interfere with your ability to concentrate or hear actual sound. Tinnitus may be present all the time, or it may come and go.

    There are two kinds of tinnitus.

    Subjective tinnitus is tinnitus only you can hear. This is the most common type of tinnitus. It can be caused by ear problems in your outer, middle or inner ear. It also can be caused by problems with the hearing (auditory) nerves or the part of your brain that interprets nerve signals as sound (auditory pathways).

    Objective tinnitus is tinnitus your doctor can hear when he or she does an examination. This rare type of tinnitus may be caused by a blood vessel problem, a middle ear bone condition or muscle contractions.
    When to see a doctor

    If you have tinnitus that bothers you, see your doctor.

    Make an appointment to see your doctor if:

    You develop tinnitus after an upper respiratory infection, such as a cold, and your tinnitus doesn’t improve within a week.

    See your doctor as soon as possible if:

    • You have tinnitus that occurs suddenly or without an apparent cause.
    • You have hearing loss or dizziness with the tinnitus.

    Causes

    A number of health conditions can cause or worsen tinnitus. In many cases, an exact cause is never found.

    • A common cause of tinnitus is inner ear cell damage. Tiny, delicate hairs in your inner ear move in relation to the pressure of sound waves. This triggers ear cells to release an electrical signal through a nerve from your ear (auditory nerve) to your brain. Your brain interprets these signals as sound. If the hairs inside your inner ear are bent or broken, they can “leak” random electrical impulses to your brain, causing tinnitus.
    • Other causes of tinnitus include other ear problems, chronic health conditions, and injuries or conditions that affect the nerves in your ear or the hearing center in your brain.

    Common causes of tinnitus

    In many people, tinnitus is caused by one of these conditions:

    • Age-related hearing loss. For many people, hearing worsens with age, usually starting around age 60. Hearing loss can cause tinnitus. The medical term for this type of hearing loss is presbycusis.
    • Exposure to loud noise. Loud noises, such as those from heavy equipment, chain saws and firearms, are common sources of noise-related hearing loss. Portable music devices, such as MP3 players or iPods, also can cause noise-related hearing loss if played loudly for long periods. Tinnitus caused by short-term exposure, such as attending a loud concert, usually goes away; long-term exposure to loud sound can cause permanent damage.
    • Earwax blockage. Earwax protects your ear canal by trapping dirt and slowing the growth of bacteria. When too much earwax accumulates, it becomes too hard to wash away naturally, causing hearing loss or irritation of the eardrum, which can lead to tinnitus.
    • Ear bone changes. Stiffening of the bones in your middle ear (otosclerosis) may affect your hearing and cause tinnitus. This condition, caused by abnormal bone growth, tends to run in families.

    Your doctor will examine your ears, head and neck to look for possible causes of tinnitus. Tests include:

    • Hearing (audiological) exam. As part of the test, you’ll sit in a soundproof room wearing earphones through which will be played specific sounds into one ear at a time. You’ll indicate when you can hear the sound, and your results are compared with results considered normal for your age. This can help rule out or identify possible causes of tinnitus.
    • Movement. Your doctor may ask you to move your eyes, clench your jaw, or move your neck, arms and legs. If your tinnitus changes or worsens, it may help identify an underlying disorder that needs treatment.
    • Imaging tests. Depending on the suspected cause of your tinnitus, you may need imaging tests such as CT or MRI scans.

    The sounds you hear can help your doctor identify a possible underlying cause.

    • Clicking. Muscle contractions in and around your ear can cause sharp clicking sounds that you hear in bursts. They may last from several seconds to a few minutes.
    • Rushing or humming. Usually vascular in origin, you may notice sound fluctuations when you exercise or change positions, such as when you lie down or stand up.
    • Heartbeat. Blood vessel problems, such as high blood pressure, an aneurysm or a tumor, and blockage of the ear canal or eustachian tube can amplify the sound of your heartbeat in your ears (pulsatile tinnitus).
    • Low-pitched ringing. Conditions that can cause low-pitched ringing in one ear include Meniere’s disease. Tinnitus may become very loud before an attack of vertigo — a sense that you or your surroundings are spinning or moving.
    • High-pitched ringing. Exposure to a very loud noise or a blow to the ear can cause a high-pitched ringing or buzzing that usually goes away after a few hours. However, if there’s hearing loss as well, tinnitus may be permanent. Long-term noise exposure, age-related hearing loss or medications can cause a continuous, high-pitched ringing in both ears.
    • Acoustic neuroma can cause continuous, high-pitched ringing in one ear.
      Other sounds. Stiff inner ear bones (otosclerosis) can cause low-pitched tinnitus that may be continuous or may come and go. Earwax, foreign bodies or hairs in the ear canal can rub against the eardrum, causing a variety of sounds.

    Noise suppression

    In some cases white noise may help suppress the sound so that it’s less bothersome. Your doctor may suggest using an electronic device to suppress the noise. Devices include:

    • White noise machines. These devices, which produce simulated environmental sounds such as falling rain or ocean waves, are often an effective treatment for tinnitus. You may want to try a white noise machine with pillow speakers to help you sleep. Fans, humidifiers, dehumidifiers and air conditioners in the bedroom also may help cover the internal noise at night.
    • Hearing aids. These can be especially helpful if you have hearing problems as well as tinnitus.
    • Masking devices. Worn in the ear and similar to hearing aids, these devices produce a continuous, low-level white noise that suppresses tinnitus symptoms.
    • Tinnitus retraining. A wearable device delivers individually programmed tonal music to mask the specific frequencies of the tinnitus you experience. Over time, this technique may accustom you to the tinnitus, thereby helping you not to focus on it. Counseling is often a component of tinnitus retraining.
    • Medications

    Drugs can’t cure tinnitus, but in some cases they may help reduce the severity of symptoms or complications. Possible medications include:

    • Tricyclic antidepressants, such as amitriptyline and nortriptyline, have been used with some success. However, these medications are generally used for only severe tinnitus, as they can cause troublesome side effects, including dry mouth, blurred vision, constipation and heart problems.
    • Alprazolam (Niravam, Xanax) may help reduce tinnitus symptoms, but side effects can include drowsiness and nausea. It can also become habit-forming

    My suggestion: besides a quality set of hearing protection, check out the latest and greatest suppressors on the market. But be careful, silencer collecting can be an affliction of its own.
