DISORDERS OF PHONEMATICAL HEARING

(suspected dyslexia):

DISORDERS OF LISTENING AND HEARING IN NOISE

(difficulties in understanding speech):

DISABILITY OF VISUAL AND HEARING INTEGRATION

(speech defects):

• abnormal functioning of the nerve structures of the posterior temporal lobe of the hemisphere, responsible for correct speech organization (the left hemisphere);

• disruption of the decoding function of the acoustic features of speech sounds allowing the distinction of phonemes (phonological type errors, e.g. replacing the phoneme /d/ with the phoneme /t/)

• difficulty in differentiating speech sounds;

• difficulties in reading and writing;

• frequent speech defects.

Hearing disorders at the phonological level are the most common form of central hearing disturbances (50%).

• impaired function of the frontal lobe, including the Broca’s region;

• poorly functioning short-term auditory memory;

• difficulties in understanding speech in unfavorable acoustic conditions;

• impaired attention of hearing concentration;

• active speech disorders―poor vocabulary, incorrect grammatical forms;

• impulsivity;

• therapy: listening training with active application of the Johansen, Tomatis, and/or Warnke methods, as well as the Neuroflowone―active hearing training;

• FM system―hearing aids or different types of hearing help equipment.

Auditory attention disorders account for 30% of central hearing disorders. They show similarity to ADD and ADHD.

• Impaired function of the corpus callosum and structures of the right cerebral hemisphere;

• Difficulties in assessing and actively using prosodic speech features;

• Difficulties in understanding speech in unfavorable acoustic conditions;

• Problems with the location of the sound source;

• Problems with visual-hearing-motor coordination;

• Reading and writing disorders (taking notes, writing dictations);

Possible forms of therapy: ear training, SI therapy, speech therapy.
