助听器刺激大脑更活跃
助听器不仅仅能帮助到你的听力,还会做的更多。它能帮助你的大脑记住那些不戴助听器就不能听得到的声音。
大多数时候,听力损失的加重是静静的。突然有一天,你发现再也不能听到电冰箱的嗡嗡声或者小鸟的叫声。
平均起来,听力损失发展到需要干预和行动之前大概是10年时间。一些听力损失患者简单的期望听力问题能够自然好转,而这鲜有发生。
未经治疗和干预的听力影响着生活质量,不但如此还会影响到大脑记忆普通日常生活声音的能力,原因在于听力通路长期闲置不再利用。
当听神经失去它们的功能,听觉通路不再传输声音信号给大脑,随着时间的过去导致大脑“忘记”这些声音并且变得不能理解它们(声音)。
记忆力衰退
在听觉开始减退之后,大脑听觉中心能够存储声音和噪声最多大概3年时间。7年之后,记忆变得越来越微弱。
因此,重要的是一旦发现有听力损失必须立刻进行听力测试和助听器选配。当选配上助听器后听力处理程序继续重新工作提供信号给大脑。
重新学习聆听
如果助听器的选配过于迟了,不管何种方法,没有助听器能够转换输入声音信号变得易于理解。意味着,大脑不再认识日常声音和噪声,比如电冰箱和电脑的嗡嗡声。大脑必须重新学习聆听。
如果对你的听力有任何怀疑,你可以看医生和进行听力测试。

Hearing aids stimulate brain activity
A hearing aid does more than help you hear. It also helps your brain remember the sounds you cannot hear without your hearing aid.
Most often, hearing loss sneaks up on you. Suddenly one day, you notice that you no longer hear the humming of the refrigerator or the birds’ singing.
On average, it takes 10 years for people with hearing loss to finally do something about it. Many people are simply waiting for the hearing problem to go away. This rarely happens.
Untreated hearing loss affects your quality of life, but it also affects the brain’s ability to remember common everyday sounds because the hearing channels are no longer effectively used.
When the hearing nerves lose their function and no longer channel sound signals to the brain, the brain ’forgets’ the sounds over time and becomes unable to understand them.
Memory weakening
The brain centre for hearing stores sounds and noises for up to three years following the onset of a hearing loss. But after about seven years the memory becomes weaker and weaker.
Therefore, it is important to have your hearing tested and hearing aids fitted when you find that you are losing some of your hearing. Once you have a hearing aid the hearing processing resumes supplying signals to the brain.
Learning to hear again
If the fitting of a hearing aid is seriously delayed, however, not even a hearing aid will be able to transform the incoming sound signals into understandable information. This means that the brain no longer recognizes ordinary everyday sounds and noises, such as the hum of the refrigerator or the computer. The brain must learn to hear all over again.
If you have any doubts about your hearing, you should see your doctor and have a hearing test.
