What is a Behavioral Audiometry Sound Field Audiometry Room

It's essentially a type of audiometric booth designed for assessing the degree of hearing loss in children aged 1-3 years. It is widely used in disease control centers and similar facilities.

Behavioral audiometry and sound field audiometry involve presenting a sound stimulus to the test subject and observing their behavioral response to assess their hearing level. Broadly speaking, behavioral audiometry is equivalent to all subjective response audiometry, and for testing younger children with hearing loss, it primarily relies on the age characteristics of the tested child, employing various methods.

A method of auditory testing to estimate the extent of a child's hearing loss.

Auditory Reflex: Newborns aged 0~3 months have not yet developed various conditional reflexes, but there exist various unconditional auditory reflexes, such as producing auditory reflexes in response to sounds.

Auditory Behavior Response: By 3 months, the auditory reflexes in a child gradually diminish, and they begin to develop定向listening abilities, paying attention to the direction from which sounds originate. During the examination, avoid the child's line of sight and present different intensities of sound from various directions to observe their reactions. Estimate the degree of hearing loss by roughly gauging the size of the sound presented.

Conditioned定向reflex: Combine sound stimuli with another type of stimulus that is easy to attract a child's attention or interest to strengthen the child's response to sound. Commonly used methods include combining sound with light or motion toys. During the examination, face the child, and while presenting the sound stimulus, simultaneously provide light and motion toy stimuli. After several repetitions, the child will form the concept of combining sound and light stimuli or sound and motion toy stimuli in their mind. Then, only present the sound without other stimuli, and observe the child.

During the examination, gradually reducing the intensity of the test sound can give a general understanding of the child's hearing. This test is suitable for children aged 1 to 3 years old.

Game-based Hearing Test: Suitable for children aged 3 and above. Designed according to children's love for play. During the test, arrange some game activities for children to accompany the hearing test process.

Pure Tone Audiometry: A subjective test conducted in an audiometric booth using a pure tone audiometer. This method has high accuracy, but requires good cooperation from the test subject, thus it is suitable for subjects aged 5 and above.
