} Aims:

◦ Identification of critical areas

◦ Designing therapeutic and promotional measures

◦ Systematic support and guidance for parents} Evaluation of therapeutic measures} Documentation of the learning processes

} Relationship between the child‘s actual age and its“hearing“ and “speaking“ age

} Prevention and intervention


k

} Regular diagnostic check-ups (every 6 or 12

months)

} Observation of the overall development

} Main focus in a check-up: hearing and speaking

} Identification of critical areas of development

} Introducing measures of intervention

} Evaluating these measures


k

} Following the guidelines of natural language acquisition

and the specified order for the acquisition of linguistic

competences

} Integration of tests, conversations with parents and

observation by therapists

} Test procedure in comfortable atmosphere for parents

and children


k

} Interdisciplinary conversations with educational/

1. Measurement of impedances(telemetry) and if necessary NRT

2. Loudness Scale� Determination CL-values (Comfortable Level)� Identification of the most comfortable level for each

electrode

3. Determination of Threshold-values ◦ like audiometrie◦ not often◦ problem: hide own movements !!!

} 4. Loudness adjustment of THR- and CL-values between neighboured electrodes (sweep)

◦ Playing the first tone of one electrode and then directly the neighboured electrode

◦ Child has to decide whether the loudness of the two heard tones are equal or not

} Discrimination between frequencies ( low and high) and loudness (loud, quiet)

} Sensibility concerning of high frequencies, butthe high frequencies are very importent for speechdiscrimination

5. decreasing/ increasing the valuese.g.◦ If the child can‘t hear the LING sounds◦ If it‘s to loud/silent◦ …

6. Checking additional map parameters, e.g.:◦ Microphone sensitivity◦ Loudness growth function◦ Input dynamic range (40dB – 80dB) ◦ AGC


k

7. Determination of the parameters, which can be adjusted by the patient him- or herself◦ Loudness, if the recipient is in a loud or silent situation◦ Microphone sensitivity, if the backroundnoise is to loud

8. creation of additional maps e.g.:◦ „everyday“, „focus“, „noise“, „music“ (Cochlear)


k

} I. Results depend on the examiner…◦ Sympathetic understanding◦ Patience and calmness◦ Good knowledge of the control panel◦ The better you know the child, the better you

are able to interpret the child‘s reactions◦ Consideration of individual preferences◦ Skills to preserve the child‘s motivation◦ experience◦ Knowledge of age: Age of life is different from

the age of development!


k

} II. Results depend on the child…◦ Power of concentration ◦ Understanding of the task ◦ Understanding of speech ◦ Cognitive skills ◦ Perceptive faculties◦ Willingness for co-operation ◦ The more the child is used to the rooms, tasks

and examiner, the better it is able to work


k

} III. Results depend on…◦ Good links to ohter professionals ◦ Communication amongst the team◦ Evaluation of match concerning audiology and

observation of parents
