Tinnitus is the perception of sound in the absence of a corresponding external acoustic stimulus, the sensations of tinnitus are generally of a uniform acoustic nature such as whistles, whistles, crickets or buzzing. It is usually a symptom of damage to the auditory system.
Types of Tinnitus
Tinnitus, is classified as objective or somato-sound if the perceived sound has an origin in the body that is audible to the examiner (for example, muscular contractions or vascular alterations near the ear) or as subjective tinnitus, which is much more common, when there is no detectable specific body sound source.
Tinnitus can be unilateral (that is, perceived only in one of your ears) or bilateral (perceived in your two ears), but it can also be described as inside the head. The perceived sensation can be constant, intermittent or pulsating. The matching of its intensity or volume can go from a subtle noise slightly above the auditory threshold, to loud or high intensity sounds. According to its psychoacoustic characteristics, tinnitus can be simple if it is composed of a single noise or complex if it is composed of several noises simultaneously.
What are the causes
Tinnitus can arise from pathological changes along the entire auditory pathway. In most cases, tinnitus develops as a consequence of cochlear injuries such as hearing loss, sudden hearing loss, acoustic trauma from exposure to noise, presbycusis, or medications that are toxic to the ear, or it can also be caused by abnormal changes in the nerve. auditory, for example microvascular compression or vestibular schwannoma.
To determine the cause and characteristics of your tinnitus, it is important to consult with the specialist who will help you, through specific tests for tinnitus, to determine which is the best management option for your case.
