It rehabs the patient and moves him/her from a situation where they are unconscious to the sound to being able to detect it. Sound detection is the initial stage and most important one. The stages are continuous and strengthening up and not isolated from each other (Chen and Lincan 4 King Abdul-Aziz University Hospital Nagawah 15). 2).Ī typical aural rehabilitation therapy processes are composed of four stages, as it explained in figure 2, starting with sound detection, sound discrimination, sound identification and ending with sound comprehension. Non-speech sounds are important as well, especially the environmental sounds like car sounds for example (Chen and Lincan 4 Swetto 1 Yin et al. In case of deaf children,Ĭonstant is more likely to percept than vowel, where a good skill of hearing should master all phoneme classes. A vowel is defined as ongoing, unchanging sound in which the oral tract is kept open from the glottis to the lips(Chen and Lincan 4).It's clearly known that the intensity of vowel is stronger than consonant, but its frequency is lower. Vowel and consonant of phoneme are considered as independent phoneme. Human speech also considered as an elementary material of an aural rehabilitation, and it's characterized by secondary phoneme and segmental phoneme, while the first refers to the rhythm, the second represents the entity unit of speech (Chen and Lincan 4 Yin et al. In daily life, we can classify sound as speech, which is generated by human sound systems, and the non speech sound as environmental sounds and noise. Human ears can accept sound intensity that ranges from 0 to 130dB SPL, with frequency amount between 20- 20000Hz (Chen and Lincan 4 Yin et al.
The sound intensity is the fluctuation ranges of sound sources. The main material in aural rehabilitation therapy is sound, which is considered as a three dimensional concept with parameters of intensity, frequency and time. By attending an evaluation with Aural Rehabilitation speech pathologists, a therapy plan is conducted along with objectives that vary according to the patient need (Aural Habilitation/Rehabilitation). Many variables control the amount of therapy needed, including when hearing loss was detected and the amount of time since that. It involves comprehensive assessment and treatment of hearing impaired people post the cochlear implant surgery on weekly basis. Aural habilitation/rehabilitation (AR) therapy refers to the process of associating sound to meaning through listening.
