  • My hearing aid is whistling

    The ear canal has a build-up of wax – have the obstruction examined and removed by a professional.

Tips for cleaning your hearing aids

  • Remove earwax. It is important to remove earwax from your hearing aid to prevent temporary malfunction or permanent damage. When you purchase your hearing aids, you should receive cleaning tools including a soft brush and small picks or loops. Follow the manufacturer’s instructions for cleaning your hearing aids. 
  • When you remove your hearing aids at night, wipe them with a dry soft cloth. Do not use water, alcohol swabs or cleaning solvents as they can break down or damage your hearing aids.
  • Remove your hearing aids from your ears prior to sleeping.

After investing in your hearing aids, you will no doubt want to keep them performing to their optimum level and for as long as possible. This overview will help you keep your aids functioning exactly as they should. It is essential that you have a daily cleaning routine. If you do not do this, the speaker (the component which provides sound into your ear) may become blocked with wax and will gradually become weaker, affecting performance. If not cleaned regularly, it will eventually stop working altogether, requiring repair or even replacement.

Wax blockage is regarded by manufacturers as your responsibility, so they are within their rights to reject any warranty claim for damage caused by wax blockage – so even more reason to prevent it. At any time, if you have difficulty in changing filters or need to go over the cleaning regime again, contact Online hearing aids Ltd and ask for help – we would prefer you to do this rather than have the aids block with wax and not perform as they should do.

To care for your hearing aids effectively you will need:
Tissues, A small brush, A hook or pick, Replacement wax filters and replacement domes.

There are three parts to your hearing aids. The wire over the ear – the speaker and the actual aid that sits behind the ear. At night, gently use the little brush supplied with the aid to remove anything on the outside of the aid. Wipe the aid with some tissue to remove any grease from the shell. Except for rechargeable instruments, open the battery door and check the battery is clean. Place the aid somewhere warm to dry. Do not place hearing aids on a radiator or in an oven to dry!
Caring for your Receiver in the Canal (RIC) / Receiver in the Ear (RITE) aids

In the morning Any wax will be hard and easier to remove. There are two areas you need to look at: examine the rubber/silicone dome that you insert in your ear. If it has perforations round it, make sure these are clear, by brushing or by inserting the filament wire into the holes to dislodge any wax. If there are no holes just brush or wipe away any wax. Periodically pull the dome off completely. Underneath you’ll see the white coloured wax filter. If the centre of this is clear – it’s fine. If the centre is clogged with wax, change it from the supply of new filters you were given and replace or change the dome. We recommend that you change the filter at least once a month (every 2 weeks would be better if you produce excessive amounts of ear wax) to ensure it is fresh as this will reduce the likelihood of the speaker becoming blocked with wax. It’s essential that the dome is firmly replaced, or it may come off in your ear.

General maintenance:

A check on domes – if they become damaged these should be replaced immediately. If they become grossly mis-shapen (they start off circular) then replace them.

Wax guards These are inexpensive compared to the price of your hearing aid, so it is a false economy not to regularly change the wax guard. If the wax guard has become clogged with wax, it is essential to replace it. To replace the filter, use the removal and insertion tool that comes with the replacement wax guards. Press the tool end (without the new guard) on to the guard on the aid and pull it should come away at the end of the tool. Turn the tool around and press the new wax guard into the hole and it will stay there – just press lightly afterwards with your finger to make sure it is firmly fixed.

General Advice

Don’t drop your hearing aids

Dropping your hearing aids on a hard surface can damage the instruments. When you’re learning how to correctly place and remove your hearing aids, do it from a seated position with a towel or pillow on your lap.

Correctly storing your hearing aids

  • When not in use, keep your hearing aids away from heat and moisture and store them in a dry, cool place. 
  • Leave the battery door open to preserve battery power when not in use if you have a hearing aid with a disposable battery.

When not to wear your hearing aids

While most new hearing aids today are designed for water resistance, don’t wear your hearing aids:

  • In the shower or sauna
  • Swimming
  • When using a hair dryer
  • While applying hair spray or other types of spray on products. Apply hair products first, and then insert your hearing aids.
  • Remove your hearing aids prior to sleeping

About hearing loss

  • How many people around the world have hearing loss?

    If you have hearing loss, you’re not alone. 750 million people worldwide have disabling hearing loss.

  • What are the causes of hearing loss?

    Many factors can cause hearing loss, such as the aging process, heredity, disease, exposure to noise, and buildup of earwax, among other.

  • What are the different types of hearing loss?

    There are three main types of hearing loss: conductive, sensorineural and mixed hearing loss. Treatment of hearing loss is dependent on an individual’s type and level of hearing loss.

  • What is conductive hearing loss?

    Conductive hearing loss results from problems in the outer or middle ear caused by infections, build-up of wax or fluid, punctured eardrums or otosclerosis (abnormal bone development). This type of hearing loss is often temporary and can sometimes be corrected or treated with wax removal, medication, or surgery.

  • What is sensorineural hearing loss?

    Sensorineural hearing loss is caused by problems with the cochlea and the auditory nerve.  It can be a result of aging or exposure to loud noise. About 90% of all adult hearing problems are due to sensorineural hearing loss, which can be treated with hearing aids and occasionally surgery.

  • What is mixed hearing loss?

    Mixed hearing loss has elements of both conductive hearing loss and sensorineural hearing loss. This means there is damage to both the outer ear and inner ear. The outer ear cannot conduct sound properly to the inner ear, and the inner ear can’t process the sound to be sent to the brain.  

  • Can loud nose affect your hearng?

    Yes, extremely loud or prolonged noise can damage your hearing.

  • What can I do to protect my hearing?

    Protect yourself from extremely loud noise or prolonged exposure to even moderately loud noise as they can cause permanent damage to the tiny hair cells inside the cochlea. If your surroundings are loud enough that you must raise your voice to be heard, then the noise is loud enough to damage your ears – wear earplugs or other protective gear. 

About tinnitus

  • What does tinnitus mean?

    Tinnitus is the perception of sound (often described as ringing, buzzing, hissing or other sounds that never seem to go away) when no actual external noise is present.

  • What are the causes of tinnitus?

    Tinnitus can be caused by exposure to loud sounds, excessive ear wax, ear infections, high blood pressure, sensory nerve disorders, and aging. Alcohol, caffeine, smoking, and use of medications can also cause tinnitus. 

  • Am I the only one who suffers from tinnitus?

    You are not alone – 10-15% of the global population experience tinnitus on regular basis.

  • Does tinnitus have a cure?

    There’s unfortunately no cure for tinnitus, but there are ways to get relief. Avoiding loud noises, monitoring your stress level, getting ample rest, moderate exercise, and decreasing your salt and stimulant intake can help reduce your tinnitus. Competing sounds, such as a radio, white noise maker or fan, can also cancel out the noise you hear in your ears.

  • Are tinnitus and hearing loss related?

    Tinnitus does not cause hearing loss, but there is a relationship between tinnitus and hearing loss. About 4 in 5 people with tinnitus also experience problems hearing. Using a hearing aid to amplify sounds has proven effective in helping to cover up tinnitus and make it less distracting. Some hearing aids come with a built-in tinnitus sound generator feature, offering flexibility by treating both hearing loss and tinnitus
