Anvil ear pro12/5/2023 ![]() They can make the wearer feel too hot and the fact that they are quite bulky means that they can feel heavy and tiresome to wear over longer periods. ![]() Large earmuffs can work well at keeping harmful noise out, but can feel cumbersome when worn for long periods. In most cases however, it is preventable, and the best way to protect these hairs is by wearing hearing protection while undertaking high noise exposure activities such as playing drums, riding motorcycles or shooting, and there are several types of hearing protectors out on the market. Unlike some animals, humans can’t regrow these damaged hairs and, as a result, any damage is not reversible. Each is attached to a nerve cell and, as they die, so the sound our brain hears becomes less clear. It is in the cochlea where these super sensitive hairs can be found. Three small bones in the inner ear (known commonly as the hammer, anvil and stirrup, but medically called the malleus, incus and stapes) then amplify those vibrations before they travel into the inner ear, where the cochlea processes the waves into sounds our brain can understand. The sound waves pass into our ears and cause our eardrum to vibrate. The ear works by processing sound waves and converting them into electrical pulses our brains can understand. It happens because highly delicate cells and tiny hairs in the inner ear become can be damaged by prolonged exposure to loud sounds. ![]() In extreme cases, very loud blasts or sudden changes in pressure can cause the eardrum to rupture, causing immediate and permanent hearing damage, but for many sufferers, noise induced hearing loss (NIHL) comes through prolonged exposure in noisy environments. Without proper protection, this damage can be irreversible – leaving the sufferer with tinnitus (a permanent ringing in the ears) and diminished hearing ability. A full shift in a typical factory may leave the worker with a ringing in their ears, while just 15 minutes riding a motorcycle at motorway speeds, or playing a musical instrument, can have the same effect. Scientists have determined that we risk damaging our hearing at above 85dB. In day to day life, a typical conversation takes place at around 60 decibels (dB) and any sounds below 85dB are considered safe, although there are many everyday sounds which regularly exceed this threshold, such as a typical kitchen blender, a ride on the London Underground and even squeezy toys for children and pets.Įxposure to these sounds may not cause immediate harm to your hearing but prolonged exposure may well do so. Of course, old age is not the only cause of hearing loss, and there are ways that we can all work to preserve our hearing. This can often be counteracted by the use of a hearing aid, which amplifies the incoming sound before sending it to the ear. Over the years, the tiny hairs and nerve cells of the inner ear can become damaged through natural wear and tear, causing a muffling of sounds. There are three main areas of the ear, the inner, middle and outer, and each plays a part in processing this sound. The ear works by processing sound waves and turning them into signals which can be understood by the brain. ![]() Naturally, aging is a major contributing factor when it comes to hearing loss. We all know that exposure to loud bangs and prolonged noise can cause hearing damage and ultimately deafness, but what is less commonly known is how it actually occurs. How noise induced hearing damage and deafness occur (and how you can prevent it)
