A sexy brand, the sort that gives you a quasi-orgasmic thrill when you walk into one of their stores, and one that is as ubiquitous as it is instantly identifiable. This morning I was on a train from Clapham Junction to Victoria – a journey of 5 minutes – and I was surrounded by four white-headphone-wearing buffoons, completely and selfishly oblivious to the leaking cacophony of rubbish pouring out from about their ears. I have a pair of these babies from Shure – in-ear, noise cancelling – I can’t hear anything but the music and no one else can hear I’m listening to Genesis – job done!
Not only are they loud, tinny and annoying – they are also the most painful headphones in the world, considering the great design job on the iPod, how come they screwed the buds up so bad?

Our quick and non-invasive diagnosis of deafness in dogs is achieved through Brainstem Auditory Evoked Response (BAER); a test where the electrical activity of the brain in response to an auditory (click) stimulus is recorded and displayed on a computer screen. BAER testing is a technique that can be used to assess the hearing status of adult animals where there is a concern about deafness, or prior to breeding and puppies before they go to their new homes.
Congenital deafness (deafness at birth) is recognised as a problem in many breeds of dog that carry the extreme piebald gene, demonstrated by a predominantly white coat. Deafness has also been reported to be associated with the gene that causes the merle coat colour, for example in the Border Collie, Australian Shepherd, Dappled Dachshund or Old Sheepdog. The merle gene is not reported to be present in breeds with the extreme piebald gene, for example the Dalmatian, but blue eyes do occur in these breeds. If you have an animal you think may have become deaf due to illness such as infection, or from a breed not usually associated with congenital deafness, it is important that your dog is seen by your local vet. In a normal-hearing dog, a series of peaks and troughs is produced which is displayed on a screen.

Unilaterally deaf dogs make excellent pets, but they carry the genetic material for deafness.
It is hoped eventually that a DNA test may be available to identify carriers of the disorder, and we are currently collecting samples for prospective study and for this purpose, we encourage breeders to always bring over the entire litter if possible.
Different types of animals can have their hearing tested using the BAER, but the other most common species we test is the cat. Cats may not be as receptive to performing the hearing test without sedation, but some will allow it with no problems. Each cat gets a certificate with his or her trace attached, and this is again verified and signed by a veterinary surgeon. The Animal Health Trust is a veterinary charity, based in Suffolk, which offers clinical referral services and diagnostic testing for horses, dogs and cats in East Anglia, across the UK and internationally.


Normally when I see stray kitten(s), they hide or flee but a couple hours ago my Dad found one by the back door that was very friendly. However I noticed the kitten didn't react to noise like when my other cat hissed and growled the the new kitten, and when I tried making noise behind the kitten her ear didn't move or anything.
My cat ignores all sounds except me meowing and calling her name and treat bags being shaken.
I'd try a variety of sounds - snap your fingers, whistle, crumple paper - see if she reacts to anything. I'm not sure if a vet could even tell for sure unless she has a physical, external, see-able cause for the deafness.
It could also be that she just has a lot of wax or build-up in her ears and has trouble hearing around it.
I don't know if I want to keep her, I have enough indoor cat and Socks just don't like any other cat. I agree that a vet visit is in order, both to check her ears and also to get her all fixed up for her new forever home.
Conductive deafness – due to interference in the transmission of sound waves to the inner ear, for example caused by a foreign body or wax in the ear canal, rupture of the ear drum or infection in the middle ear. Sensorineural deafness – results from damage or defect in any part of the auditory (hearing) pathway from the cochlea in the inner ear, via the auditory nerve to the auditory cortex of the brain.
Congenital deafness – present at birth, while late onset deafness, as its name suggests, occurs later in life, such as hearing loss associated with old age. Inherited deafness - passed down through one or both parents, whereas acquired deafness is due to external factors such as injury or disease. Such breeds include Dalmatians, English Setters, white Boxers and white English Bull Terriers. Absence of pigment in one or both irises resulting in blue eye colouration may also be present in merle dogs. Because of the recognised relationship between blue eyes, white coat and deafness in cats, an association between blue eyes and deafness in dogs was suggested. If they think that a hearing test is required, they will be able to refer you to us for an appointment. It is not possible to assess hearing in puppies before the ear canals open at 12-14 days as sound waves cannot enter. The optimum time to begin the testing is when they have settled down, therefore a quietening down period is factored into the time allocated for each litter. A series of clicks are passed into the ear through a headphone and they are in turn passed into a specialised electrodiagnostic machine. BAER testing can identify whether your animals are deaf in both ears (bilateral deafness) or in one ear (unilateral deafness). Trace 1 on the left is from the deaf ear at 80dB, trace 2 at 100dB, showing contralateral recordings that are eliminated by masking the other (hearing) ear with "white noise" in trace 3.


As the condition is hereditary, it makes sense not to use affected individuals for breeding. Until we achieve a DNA test, the only way to know with certainty the hearing status of each individual, and go some way towards reducing the percentage of affected dogs, is to evaluate each animal using the BAER test. White cats, especially those with one or more blue eyes, are also prone to congenital deafness, and may be tested in the same way as dogs.
However, owners are requested to bring cats and kittens in without having had food on the day of the test, just in case. As with dogs, if you are concerned that the deafness is not congenital, please consult your veterinary surgeon. Through its research programmes it develops new diagnostic tests, treatments and vaccines to help thousands of animals.
Another thing that cats almost can't resist reacting to is bird sounds - if you have a smartphone (or do this on the computer), pull up a YouTube video of a crow cawing or other birds chirping and turn the sound way up. So she does have hearing but I don't know if she is just ignoring other cat or has some hearing issue. The vibrations set up waves in the fluid of the cochlea, the spiral-shaped structure in the inner ear.
Blue iris colour is caused by a lack of pigment in the iris, and it is thought that this may reflect a lack of pigment cells in the inner ear, which is linked with this kind of deafness.
The test can be carried out at any age after this, including on adult dogs; however, many breeders wish to know the hearing status of their pups before they go to their new homes. It may be necessary to sedate a pup over the age of eight weeks, but this is a last resort; it is always attempted un-sedated in the first instance. There is no partial deafness in these cases and the deafness is irreversible and permanent. Work in the US showed that in unilateral-to-normal matings, the prevalence of affected offspring is approximately double that obtained from matings where both parents have bilaterally normal hearing. Kittens may be tested from eight weeks of age onwards and it is always attempted without sedation first. The change in pressure ultimately causes movement of the hair cells inside the cochlea that are connected to the auditory nerve. BAER testing can provide an instantaneous yes-or-no result through the assessment of the waveforms generated through the test.
Older animals are requested to come in without having eaten on the day of the test, just in case sedation is required.
It may therefore be possible to reduce the prevalence of unilaterally or bilaterally deaf puppies if only bilaterally normal hearing parents are used for breeding.
