Hearing & Tinnitus
Pitch perception in the range of 250Hz to 6kHz is important for speech recognition. An audiogram will test up to 8kHz. For frequencies higher than this the brain is analysing harmonics, detecting minute time delays in neural signals to give direction in free space to the origin of a sound source.
Tinnitus is a complex audiological and neurological condition, which when related to age is commonly linked to hearing loss, usually within these higher frequencies.
It’s a serious health condition that can negatively affect a sufferer’s quality of life and there is presently no known cure but with perseverance the perception of Tinnitus can be significantly reduced.
Sound based therapies have been the most successful of all non invasive methods at promoting selective attention and lowering perceptual processing by the central nervous system.
Tinnitus and its Symptoms
Described as a subjective disorder, Tinnitus is most common in people aged between 40 and 70, but can affect those of all ages.
Sufferers describe it as a constant or intermittent buzzing, ringing, rattling or a general persistent noise that others cannot hear. Tinnitus can develop suddenly or slowly over time and is not always attributable to specific lifestyle factors or causes.
For some people, Tinnitus is short-lived and triggered by temporary and curable conditions, such as prolonged exposure to loud noises, ear wax build-up and infections.
In more serious cases, Tinnitus sufferers can live with the disorder full-time. Long-term sufferers can find it has a negative impact on their productivity, concentration, sleep patterns and mental health.
An estimated one per cent of the UK population experiences severe Tinnitus that affects their quality of life.
Currently there is no way to cure Tinnitus but the first step is always to seek medical advice to determine the cause. Treatment options that exist are largely focused around therapy such as cognitive behaviour therapy CBT, counselling, retraining therapy and hearing loss correction methods.
Present therapy seems to favor masking the phantom noise with real noise using devices which are worn for long periods in the hope the brain will learn to ignore the the Tinnitus (habituation).
About Tinnitless®’s Creator ( a different approach)
Tinnitless® was developed by an audio engineer from the north-east of England with over forty years of experience in the industry.
After developing Tinnitus which was diagnosed as age-related, he used his professional experience to design a device which would alleviate his own symptoms. However, in the process he realised that the device had the potential to help others with the same condition.
Fast-forward two years and he has designed and tested the prototype.
