They are neither distracted nor overwhelmed by common sounds and often react automatically, knowing just what to do when they hear familiar noises like the school bell or the alarm clock. Most children function in noisy environments without missing a beat. A child with a functioning auditory system is able to filter out sounds that are not important, such as a friend tapping his pencil on the neighboring desk, while tuning into sounds that are important, such as the teacher’s direction to start working on an assignment. They are able to follow verbal directions from their teacher or parent. A Healthy Auditory SystemĬhildren with healthy auditory systems are able to respond to sounds naturally, looking when their names are called or turning their heads toward a sound. The inner ear and the sense of hearing also contributes to our vestibular system, helping us with movement and balance. In general, the cochlea translates and interprets every sound we hear (what is it?) and the vestibule helps move the sound along to the brain to integrate the sensations we receive and help process motor responses to the sound (what should I do next?). The inner ear has two important organs that, as partners, have big jobs. What should we do next? What is going on around us? Is the sound alerting us to something dangerous or important, like a fire alarm or a honking car horn? Is the sound quiet and calming, like classical music or the whirring of a fan? When we hear a sound, it travels to our brains to be analyzed in order for us to generate a response.
