Components of the standard neurologic examination are found in Table 1 and discussed in detail in this review ( table 1 ). The text is adapted, with permission, from Reference 1 [ 1 ]. The examination of comatose patients is discussed separately. The acoustic reflex threshold (ART) is the sound pressure level (SPL) from which a sound stimulus with a given frequency will trigger the acoustic reflex. The ART is a function of sound pressure level and frequency. People with normal hearing have an acoustic reflex threshold (ART) around 70–100 dB SPL. People with … Ver más The acoustic reflex (also known as the stapedius reflex, stapedial reflex, auditory reflex, middle-ear-muscle reflex (MEM reflex, MEMR), attenuation reflex, cochleostapedial reflex or intra-aural reflex ) is an involuntary Ver más Most of the time, the stapedius reflex is tested with tympanometry.
