Abstract:
Intention of paedaudiology is to detect and to evaluate hearing loss in children. In new born and small infants, in children with behavioral disorders and multiple disabilities, the clinical techniques of audiometry are often not useful. The brainstem audiometry is a reliable alternative and not so cost intensive and time consuming as it is often assumed. Encouraging is this technique in regard of hearing aids: prevention of attaching unnecessary hearing aids, ruling out not appropriate fitted hearing aids and proper habilitation of unilateral hearing loss.

01:31Hearing
When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
01:13The Cochlea
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.
01:15Auditory Pathway
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
