Software

VA-Lab is developed based on the international standards and OTOCUBE experiences in acoustics. It is bases on MATLAB® . This is a the high-level language and interactive environment used by millions of engineers and scientists worldwide.  These experiences span from environmental, architectural, industrial, and audio acoustical measurements. VA-Lab has module design with the special applications according to ISO standard requirements, such as Sound Power, Sound Insulation, and Impedance

Measurements. FFT Analysis: general signal analysis including FFT,CPS, Transfer Function,Cohe rence , Auto Correction , Cross, Correction, Cepstrum, etc. Data can be captured and saved in real-time mode. 1/n Octave: general 1/n octave analysis for sound and vibration signals, n=1,3,6,9,12,24. Calibration: user selection of sound or vibration calibration. Signal Generator: sine, square, triangle, sawtooth wave, white noise, pink noise, frequency sweep, multi-tone, tone burst, wavefile, etc. Record: Wave file or time series signal record and play back.

You can also  buy a commercial software package A§E at OTOConsult. This is a set of psycho-acoustical tests to be used by the professional audiologist. It is designed to test hearing impaired children and adults who are typicaly aided with a conventional hearing aid, cochlear implant or other device. All tests are speech- and language-independent, and supraliminal (above-threshold).

 A§E tests include levels of detection, discrimination and identification:

  1. To assess the intensity coding of sound (loudness scaling)
  2. To assess the spectral coding of sound (phoneme detection, discrimination and identification)
  3. To assess the low frequency temporal coding of sound (intonation tasks, word stress pattern, sentence intonation)
  4. In addition, a two-loudspeaker localization task to assess the central fusion of binaural hearing is contained underneath.
