Tinnitus Notch Therapy

New: Signia Notch Therapy

As part of our commitment to always provide you with the most comprehensive and effective toolkit of tinnitus therapy options, we’re pleased to introduce a new and clinically proven tinnitus therapy approach. Notch Therapy is Signia’s proprietary and patented sound therapy, which has been shown to be especially effective against tonal tinnitus, a very common type of tinnitus.

Unlike other therapy approaches that work by providing an additional noise or audible sound to the patient, Signia Notch Therapy provides amplification with a notch filter set to correspond to the individual’s tinnitus frequency.

Setting up Notch Therapy for your tinnitus patient is easy, and requires no specialized training. Connexx intuitively guides you through some simple steps to determine your patient’s tinnitus frequency, and automatically sets up the notch amplification in the hearing aid accordingly.

The human ear consists of three parts – the outer, middle, and inner ear.

 

Outer ear: The outer ear picks up sound and transmits it to the eardrum via the ear canal

 

Middle ear: Sound waves cause the eardrum to vibrate. The ossicles, called malleus, incus, and stapes, pass the vibration on to the inner ear.

 

Inner ear: The cochlea converts movements of the ossicles into electrical signals. The auditory nerve transmits the signals to the brain.

The following video demonstrates how hearing works:

Hearing loss

Hearing loss generally develops slowly over many years; the effects become apparent only gradually. This makes it difficult for those affected to recognize that they are actually suffering from a hearing impairment. Relatives, friends or colleagues are often the first to realize that something is wrong.

For a simplified example, if the patient’s tinnitus is centered around 1,000 Hz, Signia hearing aids can be set to provide amplification for the patient according to their hearing loss across the frequency range, with the exception of at 1,000 Hz. This therapy technique utilizes cortical lateral inhibition, a neural mechanism that reduces the activity in the over-stimulated region of the brain responsible for many types of tinnitus, and has been shown in multiple clinical studies to be highly effective.

Possible impacts of hearing loss:

  • Decreased attention
  • Diminished understanding of speech
  • Trouble communicating with others
  • Diminished memory
  • Less willing to embrace the unknown
  • Declining job performance
  • Lack of acknowledgement by others
  • Irritability, stress, depression
  • Withdrawal from social life, isolation

Hearing impairments can occur in all parts of the ear; dysfunctions of the outer or middle ear can generally be treated with medication or surgery. However, a good 80 % of all hearing impairments are caused by dysfunctions of or damage to the inner ear. Today, modern hearing aids can compensate for most inner ear damage.

 

However, no two cases of hearing loss are the same. Most often people with a hearing impairment are unable to distinguish soft tones and high-pitched sounds and have difficulties hearing sounds such as whispers, children’s voices or birdsong.

This video helps to understand hearing loss:

Binaural hearing: two ears hear better than one

Nature gave us two ears for a reason: Binaural Hearing, or hearing with both ears, helps us localize sounds no matter where they come from. It also allows us to precisely focus on what we want to hear by letting us perceive certain sounds like speech louder and clearer while ignoring others. A few of the most important binaural processes include binaural redundancy, binaural squelch, and binaural directed listening. 

Binaural redundancy

When we hear a sound in both ears, it’s like hearing the same sound twice. This helps our brain create a better perceptual image of the sound. With hearing loss, this effect is significantly reduced. Wearing two hearing instruments helps to bring back the benefit of binaural redundancy.

Binaural squelch

In situations where there is both noise and speech, hearing with both ears helps our brain to give speech sounds preference to noise. This makes speech seem louder than it really is. With hearing loss, this effect is significantly reduced. Wearing two hearing instruments helps to bring back the benefit of binaural squelch.

Binaural directed listening

In noisy situations with many different sounds coming from different places, hearing with both ears helps our brain pick out the one single sound source we’re interested in and focus on it. With hearing loss, this effect is significantly reduced. Wearing two hearing instruments helps to bring back the benefit of binaural directed listening.

Take action now

It is only when hearing starts to deteriorate noticeably that we realize just how important good hearing is in our everyday lives. And how much we miss out when we no longer hear well.Why take action as soon as possible?

Hearing loss is a gradual process

Hearing loss is usually a gradual process that takes many years – so gradual that we don’t immediately recognize its negative effects in our lives.

Untreated hearing loss impacts our lives

Communication problems with family, friends, and colleagues can lead to irritability, stress, isolation, and even depression.

The sooner the better

The earlier we are properly fit with hearing aids, the better, even if you only have slight hearing loss.

Training your brain

When you hear well again with hearing aids, the brain is stimulated and mental vitality is maintained.

Get more out of life

Quality of life is enhanced, resulting in unrestricted interpersonal communication and social interaction.
