Neuro-Audio-Screen General Properties

Neuro-Audio-Screen — autonomous device which can be put in a doctor’s smock pocket. It allows choosing a checkup type, entering a patient’s data; controlling a checkup process, displaying results and storing exams in database. It is possible to process and archive the checkup results on the external computer.

Available languages: Russian, English, Turkish, French, etc.

The results can be printed on a portable printer connected via wireless Bluetooth interface.

Stimulus volume during an exam is up to 60 dB nHL.

Techniques:

• Auditory brainstem response / brainstem evoked response audiometry (ABR / BERA / O-ABR)
• Transient evoked otoacoustic emission (TEOAE)
• Distortion product otoacoustic emission (DPOAE)

Why is it Important?

The hearing impairment is diagnosed in three of every thousand babies born, that is twice more than frequency of cleft lip (palate), twice more than frequency of Down’s syndrome and ten times more than frequency of phenylketonuria.

The problem of diagnostics and treatment of hearing loss and deafness in this special category of patients is actual both in medical and social relations. Often the visual examination and other traditional diagnostic techniques of hearing impairment detection do not reveal the problem until 1 to 3 years of age — which is well beyond the critical period (6 months) for healthy speech and language development.

However, if a hearing impairment is identified and treated in its early stages, studies have shown that the child’s speech and language skills will be comparable to his or her normal-hearing peers. For these reasons, hearing screening at birth and routinely throughout childhood is extremely important. Timely and correct diagnosis provides an opportunity to start the hearing rehabilitation and child integration to speech environment as soon as possible.

What Should be Done?

Earlier to solve the specified problem, the hearing screening of newborns and babies was applied. It was based on the consideration of risk factors with the further examination of babies, included in the risk group, in specialized establishments. However, at such approach 50% of children drop out of sight.

The only possible solution of the problem concerning early detection and rehabilitation of children suffering from hearing loss and deafness is introduction of hearing screening with the use of objective technologies in maternity hospitals and maternity departments of patient care institutions.

At present time, the fundamentally new so called objective techniques of hearing study are developed and applied in clinical practice, they are computer audiometry by auditory brainstem response (ABR) and recording of otoacoustic emission (OAE). It allows performing hearing study in any age, even in newborns.

Neuro-Audio-Screen device manufactured by Neurosoft Ltd. provides the best solution for newborn hearing screening using the techniques of OAE and ABR.
"Pass" or "Refer" results are given after each test.

TEOAE test results	Neuro-Audio-Screen Features OAE At present moment, the most important technique at the hearing screening of the newborns is the otoacoustic emission study. It is accurate, informative and at that simple for carrying out and saving the time resources technique. It is expedient to perform OAE to all babies before one year (even not once). If OAE is registered (test is passed), the baby’s hearing is not impaired. In case OAE is not registered, it is the indication to see an audiologist to perform the further examination of the baby. Otoacoustic emission is the acoustic response which reflects the normal functioning of the auditory receptor. It is an extremely weak audio fluctuations generated by cochlea which can be registered in the external auditory meatus with the use of highly sensitive noiseless microphone. These fluctuations are the result of active mechanical processes running in the Corti’s organ, namely in external hair cells. OAE is more convenient for screening study as it takes little time. It is very important also because the long-term immobilization of a child is sometimes impossible. Several variants of this method exist, but in practice the most often used ones are transient evoked otoacoustic emission (TEOAE) and distortion product otoacoustic emission (DPOAE). ABR / BERA / O-ABR The essence of this technique is the registration of the electrical potentials emerging in different structures of auditory system (from auditory nerve up to cerebral cortex) in response to audio signal which defines its objectivity. The widest application in audiology has auditory brainstem response (ABR) or brainstem evoked response audiometry (BERA) or short-latency auditory evoked potentials. The advantages of this technique: ABR can be registered in newborns from first hours of their birth including prematurely borns and newborns suffering from central nervous system pathology ABR registration is non-invasive (safe and harmless) ABR registration provides objective information concerning the condition of auditory pathway state and central nervous system ABR characteristics are stable and do not depend on a patient’s state (whether she/he is awake or sleeps, this sleep is natural or drug-induced) At two-stage technique of hearing screening, in case a child did not pass OAE test, a doctor should carry out the ABR test to specify the diagnosis.

All the techniques are performed in automatic mode. The checkup results are displayed on the screen immediately and if the thermal printer with wireless Bluetooth interface is available (is not included in the base delivery set), it is printed on the thermal paper. All these possibilities are very important for the screening.

Two delivery set variants are available: Neuro-Audio-Screen and Neuro-Audio-Screen/OAE
All devices are calibrated at Neurosoft facilities. NO TEXT
