The Psycho-listening Test measures the ability of the ear to listen, that is, to become conscious of sound and to respond. In other words, it measures active selective listening and not hearing. This is its main difference from the auditory test, the diagnostic tool of otorhinolaryngology and audiology. The test includes the following components:

  •  The air conduction curve
  • The bone conduction curve
  • Active selective listening
  • The localization of the direction of the sound signal (through air and bone conduction)
  • Audio-vocal control
  • Auditory lateralization for language (right or left)

The findings or the deviations from the “ideal” listening curve give us valuable information on possible dysfunctions in the area of active selective listening, on the energizing function of the ear, on the control of gross and fine motor coordination, on the ability to communicate, to learn, to concentrate, to memorize. The ideal listening curve of the ear in the region that we measure (125-8000 Hz) is a curve that ascends 5 dB per octave, forms a “dome” in the region between 2000-4000 Hz and descends slightly at 6000 and 8000 Hz.

The Psycho-listening Test uses a different calibration and administration procedure from standard audiometry. As a result of these differences, the qualitative information that it provides is closer to the way the ear perceives sound. The ideal listening curve constitutes a unit of measurement or reference point, since it is seldom found in persons. Deviations from the ideal listening curve reveal the neurosensory defenses and shields of the ear as a receiver of information from the cortex, when the person wishes to avoid something or to withdraw from something that is psychologically painful. For example, a closed selectivity is likened to a closed “emotional curtain” that keeps out what is undesirable.
