For instance, two recognized sources of high-pitched sounds might be electromagnetic fields common in modern wiring and various sound signal transmissions. A common and often misdiagnosed condition that mimics tinnitus is radio frequency (RF) hearing, in which subjects hear objectively audible high-pitched transmission frequencies that sound ...
In many cases, worsening, high-pitched tinnitus and hearing loss are linked to damage from noise exposure over time and can hit suddenly or worsen gradually, per a 2016 study in Noise & Health.
High frequency hearing loss causes a high pitched tinnitus and low frequency hearing loss causes a roaring tinnitus. [19] Noise-induced tinnitus can be temporary or permanent depending on the type and amount of noise a person was exposed to.
Tinnitus is described as hearing a sound when an external sound is not present. [13] Noise-induced hearing loss can cause high-pitched tinnitus.

A 1973 report cites a university study of fifty cases of people complaining about a "low throbbing background noise" that others were unable to hear. The sound, always peaking between 30 and 40 Hz (hertz), was found to only be heard during cool weather with a light breeze, and often early in the morning. These noises were often confined to a 10 ...
Tinnitus, difficulty hearing high pitched sounds (such as birds singing or cell phone notifications), and trouble understanding speech in background noise can be indicators of hearing loss. Getting a hearing test regularly.
Over time, the detection of high-pitched sounds becomes more difficult, and speech perception is affected, particularly of sibilants and fricatives. Patients typically express a decreased ability to understand speech. Once the loss has progressed to the 2–4 kHz range, there is increased difficulty understanding consonants. Both ears tend to ...
