What time does Taiyuan Angel Children's Hospital go to work in the afternoon?

1 point. Oh! Behavioral audiometry refers to giving the testee a sound stimulus and observing the testee's behavioral response, so as to understand his listening level. According to the age of the children, different audiometry methods are used to evaluate the degree of hearing loss of children.

There are three ways to test a child's behavior:

1. Behavioral observation audiometry (BOA): It is suitable for children aged 0-6 months and can be used as one of the evaluation methods of newborn hearing screening. Behavioral observation audiometry is to observe children's behavioral responses to stimulating sounds through toys or equipment in a relatively quiet environment, such as observing children's behaviors such as sucking, shaking limbs and jumping, and never judging children's listening situation.

2. Visual enhanced audiometry (VRA): suitable for children from 6 months to 2 years old. After children's conditioned reflex to acousto-optic stimulation is established, visual stimulation is used as the strengthening means to observe children's response to sound. The purpose is to let children establish a conditioned reflex to the stimulus sound, and their local response to the stimulus sound will be rewarded. At the same time, they will be attracted by the flashing toys with rewards, and use the directional reflection with rewards to encourage children to continue to turn their heads in the direction of the sound source even when the stimulating sound itself is no longer interesting, so as to obtain their listening situation.

3. Play audiometry (PA): Suitable for children aged 2-8. Game audiometry combines stimulating sounds with various games, so that children can establish conditioned reflex of audiometry, participate in an interesting game and teach children to make clear and reliable responses to stimulating sounds.

Behavioral audiometry or pure tone audiometry can provide a lot of important information. Due to the limitations of various objective audiometry methods such as brain stem ABR or multi-frequency steady-state ASSR, it is necessary to judge children's hearing by combining the results of behavioral audiometry. Whether the results of ABR or multi-frequency steady-state ASSR are analyzed or calculated by the auditory unit of behavioral audiometry, they can be used as the basis for children to choose or debug hearing aid cochlea. At present, the objective audiometric results of brain stem ABR or multi-frequency steady-state ASSR can only predict the hearing situation, which has errors with the real hearing. Our advice to parents: Your baby must do pure tone behavior audiometry, air conduction audiometry, bone conduction audiometry and FF effect evaluation audiometry after hearing aid.

Although behavioral audiometry is simple, the detected hearing situation reflects the function of the whole hearing system at various frequencies, not only physiological and physical processes, but also a large number of psychoacoustic processes. Behavioral audiometry is the gold standard of international listening assessment.
