    How do you clean your ears sufficiently to use such things?

    I'd imagine if you have waxy ears that they must push it all the way in before insertion.

    Some of the clinical websites that sell these ear plugs suggest that if you have wax problems that you should see a medical practitioner to have all your wax removed before having the fitting performed.

    My son uses custom made ear plugs when he races Suoerkarts and he had to have his ears syringed before they took the moulds of his ears. Some time later he had hearing issues and he found that inserting the ear plugs had pushed the wax and compacted it further into the ear canal. The only reason he had them made was because he needed to be able to have radio communication and race announcements and they had speakers in them to do just that.

    A couple of things with noise reduction that I picked up over 20 years as a construction and mining safety manager
    The best hearing protection is not always the one with the greatest NRR rating as you still need to hear some of the surrounding noises, a good rule of thumb is to measure the noise levels at the noise source (smart phone apps work well enough for this) and then select hearing protection NRR to give a noise level at the ear of about 75 dB (eg if the typical noise source is 95dB then you will need a NRR rating of 20 which is a Class 3 on the SLC80 scale), keep in mind that each machine in the workshop will emit different noise levels so aim for the loudest to select hearing protection. Even if the NRR is overstated by the manufacturer this will still give a good level of protection
    Any machine that exceeds 110 - 115 dB will need both ear plugs and ear muffs, in this case the ear plugs are said to play a greater role in noise reduction so aim for the NRR of the plugs to be as high as possible
    Ear muffs that don't seal properly are useless as an effective hearing protection. Failure to seal properly can be for a variety of reasons, (eg wearing glasses, old and stiff ear cushions, lack of clamping pressure, chewing gum etc) so ear plugs are generally more effective if they are inserted properly but they are a pain to keep clean
    Statutory noise levels are for an 8 hour day and in WA are 85dBA (this is widely recognised as a noise level that still cause hearing damage if the exposure is over several years which is why I recommend using a target of 75dB when using the NRR system to select hearing protection).
    Happy to answer any specific questions that anyone has

    By PM if you prefer

    Get a Doctor/nurse to clean out your ears. Not rocket science.
    I get it done once a year, have waxy ears. Mild pressure washing with very warm water.
    Absolutely disgusting, puking results but the result sure feels good.
    Ram the wax into your inner ear with ear plugs? You some special kind of crazy?

    Once a year is nowhere near often enough if you use ear plugs constantly, you would have to be crazy to leave it that long.

    I use in ear headphones up to five times a week, I'm 34 an have never had mine cleaned. If the wax reduces the sound getting to me eardrum that is good isn't it? Hahaha! I do have pretty waxy ears but they seem to sort themselves out if wax does get pushed in. At sound engineering school they said you should go at least every six months if you want to be a sound engineer.

    At my last medical the person said that no one will get anything past me as my hearing is really good, I was pretty surprised as I haven't been kind to my ears.

    EDIT- This thread has gone may OT!
