KSAFA SYSTEM EFFECTS

By the application of KSAFA system, the onset of pseudomental retardation is prevented in 30% children (aged 0–3) with verbal communication disorders.
By the application of KSAFA system, in 88% children with different degrees of hearing impairment, speech and language are fully developed so that they can be included in the regular education system.
By the application of KSAFA system, the length of the treatment of children with undeveloped speech and language and speech pathology is reduced by 50%,
The Institute for experimental phonetics and speech pathology provides extensive help and support to the users of KSAFA system.


KSAFA-m

KSAFA-m (Kostic's selective auditory filter amplifier) diagnostic–educational apparatus is intended for early habilitation of speech and language of:
- children with different degrees of hearing impairments,
- children with undeveloped speech communication,
- and children with pathological patterns of speech communication.
KSAFA-m is applicable for individual work in clinical practice, at school, in kindergartens, at home etc.
KSAFA-m can be easily and precisely adjusted, depending on the cause, degree and kind of speech communication impairment.
KSAFA-m has independent change of parametres: amplification, central frequency, width of a band-pass filter around central frequency for the left and/or the right ear.
KSAFA-m apparatus provides first-class results with minimal efforts of the therapist.
KSAFA-m apparatus is simple and easy to use in health institutions, schools and kindergartens.
KSAFA-m apparatus requires minimal investment compared to the effects it provides.
KSAFA-m apparatus guarantees high quality that is provided through the total control of the production process and included servicing.

DESCRIPTION
