The disappearance of one or two words during a conversation is quite different from the inability to hear words spoken when the speaker is turned off. There are varying degrees of hearing loss correspond to the range in dB (dB HL). Despite the degree of hearing impairment, it is important to understand the cause and hearing that will help you more. Each model of hearing aids, along with the included technology, can serve every degree of hearing impairment differently. Some models are better for certain levels. If you are unsure of the hearing that can help you, consult your doctor or hearing specialist. The varying levels of hearing loss are classified as follows:
Level of hearing loss —- Range in decibels (dB HL): Profound —+91
Severe —- 71-90 Moderate-severe —- 56-70 Moderate —– 41-55
Moderate —– 26-40 Slight ——– 16-25 Normal —– 10-15
Deep hearing loss means that a person cannot hear most sounds and is likely to communicate through sign language or lip reading. A slight loss of hearing occurs when it is difficult to hear a person while in a noisy environment or a distant person. If you cannot understand what a person is saying when you are away from you, you may have a moderate or moderately severe hearing impairment. People with moderate hearing impairment may be able to understand vowels but not consonants. Conductive hearing loss, where there is damage to the outer or middle ear, makes it difficult to hear low-frequency sounds (vowels). Sensory hearing loss, which occurs when the inner ear is damaged, results in low-frequency hearing (static).
When you choose a hearing aid, you want to make sure it serves a few purposes. First, you should be comfortable, or you’ll find that you simply will not wear it. After that, both the degree of dB and the frequency level should be absorbed. Otherwise, you will not be able to hear it. Most hearing aids, even those available without a prescription or a free hearing test, include features that increase hearing ability. Of course, these features are up to each R & D team of the manufacturer. The most common features are:
A directional microphone, which amplifies the noise coming from the direction faced by the wearer. This can be particularly useful in crowded environments and noise. Cancel comments. No one likes that loud sound that the headphones emit, and if you can’t hear the noise, it can be embarrassing if you do not know it is happening. Most hearing aids have a type of comment cancellation technique to reduce or remove comments. The devices in the channel tend to get fewer notes than the models behind the ear.
Zoom in. Adjusting the sound zoom allows the wearer to adjust the direction from which the volume will be magnified manually. Finding the perfect fit can take several models and combinations until you find a device that works for you and your hearing impairment. Look for a place with a grace period where you can return the device if you are not satisfied.
