Medial Olivocochlear Reflex (MOCR) is still poorly understood, although its action in inhibiting otoacoustic emissions has been explored since the 1980s. Its inhibitory effect results in otoacoustic emissions amplitude reduction when the efferent system is activated by noise. MOCR estimated by transient otoacoustic emissions (TOAE) is measured in decibels, but the percentage reduction mea…
The search for effective methods in the early diagnosis audiological is a great concern for the professionals. The goal of screening is to identify possible changes of the hearing as early as possible. The otoacoustic emission tests identify outer hair cells dysfunctions that affect the cochlea. However, the measurement is influenced by the middle ear status. The reflectance of the middle…
In comfortable situation of listening, as in quiet environment, the normal sensibility for pure tones can depend on the activity of only a restricted number of the inner hair cells (IHC) and the respectively associated neural fibers. The otoacoustic emissions are resultants from somatory effect of IHC activity, and may be more sensitive to initial cochlear dysfunction. To verify the influ…
Introduction: Superior Semicircular Canal Dehiscence (SSCD) consists of an opening in the otic capsule that alters cochlear hydrodynamics and results in conductive hearing loss without middle ear involvement. Therefore, this study hypothesizes that the non-linear mechanisms of the cochlea may be impaired in conductive hearing loss due to SSCD. It is believed that, despite presenting condu…
The acoustic reflex of the stapedius muscle is the result of strong sound stimulation. Its threshold corresponds to the lowest intensity of the activating stimulus capable of producing this muscle contraction, thus modifying the middle ear immittance. The acoustic reflex functions, among others, are related to the improvement of auditory attention and speech intelligibility and the attenu…
The acoustic reflex threshold measures the lowest sound level that triggers a middle ear response. If the magnitude of the response for each sound level is plotted on a graph, the growth curve of the amplitude of the acoustic reflex can be plotted. People with auditory function integrity are expected to show a typical growth curve pattern. Thus, in addition to the acoustic reflex threshol…
Otoacoustic emissions have the objective of evaluating the cochlea functioning mainly of the outer hair cells (OHC), helping in the audiological diagnosis of cochlear lesions. The Input/Output Growth Function provide information about the threshold and the nonlinear mechanisms within the cochlea that are associated with OHC. Auditory processing is the ability to transform acoustic energy …

The incudomalleolar and incudostapedial joints are true diarthroses and, therefore, may be subject to the same rheumatic lesions as other articulations in the body. Research studies have been undertaken to discover the existence of typical inflammatory alterations in the middle ear joints and their relationships with functional audiological, In patients with RA, both sensorineural hearing…
