Particular causes of hearing loss will be show up in the clinical audiogram in characteristic ways.
Conductive hearing loss comes about when the transmission of sound to the inner ear is impaired, perhaps due to impacted ear wax (cerum), an ear infection (otitis media with effusion or OME), or calcification of the middle ear ossicles (otosclerosis). It is often possible to treat conductive hearing loss by removing the cause of the physical obstruction. By far the most common cause of sensory neural hearing loss is damage to sensory hair cells in the cochlea.
Because our outer and middle ear transmits frequencies near 4 kHz very efficiently, hair cells that are tuned to frequencies near 4 kHz are particularly vulnerable to noise damage.
Even if we avoid exposure to very loud noise, the ear's outer hair cells may also simply wear out as we age, leading to age related hearing loss.

If you think that you have a hearing loss and would like to talk about it with an experienced audiologist, please make an appointment for a full hearing assessment. There is no obligation to buy and you will have the opportunity to discuss your concerns, learn the exact nature of your loss and consider possible solutions.
The following list of questions, while not exhaustive, will provide good indication of any hearing problems. If you have answered 'yes' to three or more of these questions, we recommend an in-depth hearing assessment with one of our hearing aid audiologists. These ear muffs feature cutting-edge noise reduction technology that blocks out only the sounds that exceed safety levels.
Conductive hearing loss tends to a loss of sensitivity across the entire range of frequencies, most commonly in one ear only. In this condition, high frequency outer hair cells tend to die off before low-frequency ones, possibly because the high frequency outer hair cells have to work harder if their job is to amplify acoustic vibrations on a cycle by cycle basis. Import charges previously quoted are subject to change if you increase you maximum bid amount. We even offer trial periods on some of our hearing aids, so you can discover just how much you may have been missing out on. Other causes include hereditary factors, prolonged exposure to noise exceeding 85 decibels (the equivalent to heavy road traffic), illness, accidents or even some medications. A proper hearing test will determine the nature of your loss, whether you require further medical opinion and whether a hearing aid can help. It will only take a few minutes and will test how clearly you can hear in different levels of background noise.
There is no substitute for a proper hearing test carried out by a trained hearing aid audiologist.
Featuring over 200 hours of battery life on two AA batteries (sold separately), hands-free operation and an LED indicator light, these ear muffs offer user-friendly noise reduction ideal for the workplace or garage. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable.


The majority of hearing loss is ‘sensorineural’, namely irreversible damage to the sound-conducting hair cells of the inner ear.
The degree of loss can range from mild to profound, and most people with hearing difficulties can benefit from using hearing instruments. Noise damage or age related hearing loss tends to produce characteristic deficits as shown in the audiograms here below. Continuing to suffer with hearing loss can significantly affect our social life and our relationships, and often leads to a feeling of isolation. Unlike conductive hearing loss, which can often be cured, sensory-neural hearing loss is in most cases irreparable, and treatment will aim to make the best use of those auditory structures that remain in tact, perhaps by boosting sensitivity through a hearing aid, or, in severe cases, by trying to bypass dead sensory hair cells with cochlear or brainstem implants. If you’re sure you’ve entered it correctly, go back to the product page, and click on ‘Add to basket’. I have never found the slot to pry the left ear muffs used to get them apart so I just pried them open at the bottom of the left side to insert the batteries. I also thought the muffs were electronic noise canceling type they cancel the noise the same way that other muffs do not electronically.
What they are is muffs with a microphone on the outside and speakers on the inside when you turn them on you can hear the outside sounds through the speakers by turning the knob you can adjust how loudness of the sound.
You can hear conversations around you during low noise and the sound is about cut off during high noise. They won't hold up to man handling like some more expensive ones but I can go through 4 pairs of these before the price even compares !!
