KSAFA-V

KSAFA-V (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-V is applicable for individual work in clinical practice, at school, in kindergartens, at home etc.
KSAFA-V can be easily and precisely adjusted, depending on the cause, degree and kind of speech communication impairment.
KSAFA-V is compatible with KSAFA-m apparatus. Thus the parametres obtained in the individual work on KSAFA-m apparatus are also used for the adjustment of KSAFA-V apparatus. KSAFA-V can be delivered with changeable number of outputs (for 2 to 9 children), each output having 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-V is realized as a digital device. For the input or change of the parametres, it uses keyboard or the serial port for the communication with the PC.
KSAFA-V apparatus provides first-class results with minimal efforts of the therapist.
KSAFA-V apparatus is simple and easy to use in health institutions, schools and kindergartens.
KSAFA-V apparatus requires minimal investment compared to the effects it provides.
KSAFA-V apparatus guarantees high quality that is provided through the total control of the production process and included servicing.

DESCRIPTION

Basic parts of KSAFA-V are:

• KSAFA-V unit
• microphone
• headphones

KSAFA-V provides the following functions:
• Changeable linear amplification of input signals within the whole frequency range characteristic of human speech
• Selective amplification of certain frequency areas for both ears
• Independent linear and changeable amplification of modulated signals for both ears within the whole frequency range characteristic of human speech
