THE LIST OF THE VERBOTONAL APPARATUSES
FOR THE REHABILITATION AND EDUCATION
OF THE HEARING IMPAIRED PERSONS,
PERSONS WITH COCHLEAR IMPLANT
AND FOR THE SPEECH THERAPY

1.

VERBOTON G10; the apparatus primary intended for the group rehabilitation and education of the profoundly deaf and of the hearing impaired children with the possibilities of the mobile or fixed wired installation in the classroom. Because of the very numerous filter responses the VERBOTON G10 is suited for the beginning individual rehabilitation too.

2.

VERBOTON G10M; the apparatus for the group rehabilitation and education of the profoundly deaf and of the hearing impaired children with the possibilities of the mobile or fixed wired installation in the classroom.

3.

VERBOTON G20; the apparatus primary intended for the individual rehabilitation and education of the profoundly deaf and of the hearing impaired persons. It is suited especially for the determination of the optimal hearing fields and for the hearing aids choosing. Because of the powerfull output amplifier VERBOTON G20 is suited for the rehabilitation work with the small group (up to 4 pupils) too.

Option: The suitcase portable model named VERBOTON G 20P

4.

VERBOTON VT15; the individual audio training apparatus intended for the teaching and home exercises of the profoundly deaf children according to the verbotonal method. It is delivered as the set arranged with one hand held microphone, one headset and with one vibrator. VERBOTON VT15 is constructed as the small dimensional line powered desktop device.

5.

VERBOTON G30L; the apparatus for the speech correction and for the teaching of foreign languages. It is primary designed for the individual work but because of the powerful output amplifier is very suited for the class work too. In this case the VERBOTON G30L can drive one loudspeaker or six headsets via the suited distribution box or via the class room installation.

Option: The suitcase portable model named VERBOTON G 30LP

6.

DIGIDEL 2000; the special verbotonal apparatus for the stuttering and aphasia therapy. It consists two channel digital delay and two filters for the modification of the time sequence of the filtered audio feedback.

DIGIDEL 2000 is constructed as the line powered desktop device for the individual treatment.

7.

IRETON G8; the wireless infrared set for the group rehabilitation and education of the profoundly deaf and small hearing impaired children. It is especially suited for the rhythmical and musical exercises. The set consist of: one infrared modulator and transmitter, four infrared radiators (prepared for the wall fastening), one charging device, one hand held microphone, one wireless (radio) microphone and eight infrared receivers built in the headphones sets.

8.

REVER 4E; the electronic device for the addition of the variable artificial reverberation to the stimulating speech signal, by the audio training of the hearing impaired persons. The reverberation time can be adjust from 0 to 2.2 s in the steps of 0.2 s. This treatment is provided for the cases of the prolonged integration time of the listening.

The REVER 4E must be connected to the input of the some individual audio trainer, for example VERBOTON G20.

9.

SPL-met G50; the special instrument for the precise measuring of the true value of the sound pressure level (dB SPL) in the headphone-ear system. This is achieved through the special measuring microphones built in the each of headphone (L and R). The signals from these micro-phones are connected to the measuring inputs of the SPL-met G50 which have the vertical light bar display calibrated in dB SPL.

10.
WN 98; battery powered white noise generator for the tinitus therapy. The output of this device must be connected to the input of VERBOTON G20.

11.

TMS 98; the third octave audio spectrum modifier for the phonetic and linguistic researches, voice therapy and speech correction. It is equipped with 24 third octave band-pass filters, which have very selective frequency responses (rolloff 60 dB/octave).

THE LIST OF THE VERBOTONAL accessories

1.

TYPE G; the special constructed dynamic stereo headphones, closed system designed for the extra high loading (138 dB SPL continuously), minimal distortion, excellent transient response, frequency range from 10 Hz to 18 kHz, impedance 70 ohms, high sensitivity (100 dB SPL at 70 mV RMS), contoured soft foam-filled polyurethane and antiallergenic coated aircushions, stainless steel headband and self-adjusting pivoting yokes insure a comfortable fit over a wide range of the head size, extra robust construction for the very reliable exploitation, coiled cord 3 or 5 m long and terminated with the metal stereo connector 6.35 mm.

(probably the best headset on the world for the rehabilitation of the deaf persons)

2.

ECM 10S/L; the hand held electret condenser microphone with the omni-directional polar pattern, frequency range from 5 Hz to 18 kHz, sensitivity 5.6 mV/Pa, extra robust metal construction resistant to the crush, special large diameter extra flexible cord (the handling loops and knots are reduced), cord length 2 m (S) or 5 m (L).

3.

ECM 17; the miniature electret condenser microphone with the omni-directional polar pattern fastened on the special on-head holder (hand free operation for the rhythmical and musical exercises), frequency range from 5 Hz to 18 kHz, sensitivity 5.6 mV/Pa, special large diameter extra flexible cord (the handling loops and knots are reduced), cord length 5 m.

4.

KERVIB M35; the special electromagnetic bone oscillator (vibrator) for the somatic-sensory stimulation of the profoundly deaf and hearing impaired children, frequency range extended to the infrasound area (to 1Hz), flexible cord terminated with mono connector 6.35 mm.

5.

VT 60; vibrating board with active area of 60x60 cm for the somatic-sensory stimulation of the small group of the deaf children, frequency range extended to the infrasound area (to 1Hz), flexible cord terminated with mono connector 6.35 mm.

6.

VS 40; the vibrating seat for the individual somatic-sensory stimulation

7.

LRV 1+1; desk top distribution panel for one headset and one vibrator with the binaural loudness adjuster.

8.

DB 5+2; the distribution box for the connection of five headsets and two vibrators with the binaural loudness adjuster for the each headset, mobile installation for the group work.
