Tinnitus is described as hearing a sound when an external sound is not present. [13] Noise-induced hearing loss can cause high-pitched tinnitus. [14] An estimated 50 million Americans have some degree of tinnitus in one or both ears; 16 million of them have symptoms serious enough for them to see a doctor or hearing specialist.
It is typically experienced as a secondary symptom of sensorineural hearing loss, although not all patients with sensorineural hearing loss experience diplacusis or tinnitus. [ 1 ] [ 2 ] The onset is usually spontaneous and can occur following an acoustic trauma , for example an explosive noise, or in the presence of an ear infection . [ 3 ]
Auditory processing disorder (APD), rarely known as King-Kopetzky syndrome, is a neurodevelopmental disorder affecting the way the brain processes sounds. [2] Individuals with APD usually have normal structure and function of the ear, but cannot process the information they hear in the same way as others do, which leads to difficulties in recognizing and interpreting sounds, especially the ...
High-frequency hearing loss is common with aging and noise exposure. Here's how to test your ears, prevent hearing loss and treat your hearing. Causes and Treatments for High-Frequency Hearing Loss
Speech sound disorders (SSDs) can arise from a variety of causes, which are generally categorized into organic and functional factors: Organic causes These include physical or neurological issues that affect speech production: hearing loss, including temporary hearing loss, such as from ear infections; developmental disorders (e.g. autism)
Traumatic noise exposure can happen at work (e.g., loud machinery), at play (e.g., loud sporting events, concerts, recreational activities), and/or by accident (e.g., a backfiring engine.) Noise induced hearing loss is sometimes unilateral and typically causes patients to lose hearing around the frequency of the triggering sound trauma. [17]
Dysacusis is a hearing impairment characterized by difficulty in processing details of sound due to distortion in frequency or intensity rather than primarily a loss of the ability to perceive sound. [1] The term is sometimes used to describe pain or discomfort due to sound, a condition also known as auditory dysaesthesia. [2]
If one is exposed to loud sound (including music) at high levels or for extended durations (85 dB A or greater), then hearing loss will occur. Sound intensity (sound energy or propensity to cause damage to the ears) increases dramatically with proximity according to an inverse square law: halving the distance to the sound quadruples the sound ...
