NeXTSTEP version

Digital Audiometer is a computer software application for investigating hearing thresholds in a 0 Hz to 22,000 Hz frequency range. It runs on popular desktop hardware, including portable computers, and does not require any external or internal proprietary devices. It is very precise, easy to use and, due to the stability of digital circuitry, needs to be calibrated only once.

The new audiometer allows for a more accurate evaluation of hearing loss, auditory problems and capabilities. It is especially useful in fitting today's more advanced digital and semi-digital hearing aids.

  • no harmonic and intermodulation distortions


The Screening Audiometer is ideal for those who perform standard hearing tests in clinics, schools or the workplace. It should be of great value to audiologists, nurses and medical professionals such as ENT doctors.

Its parameters also make it an ideal instrument for research and teaching in the fields of acoustics, psychoacoustics, audio, electroacoustics, audiology and speech pathology.
