Puberphonia (also known as mutational falsetto, functional falsetto, incomplete mutation, adolescent falsetto, or pubescent falsetto) is a functional voice disorder that is characterized by the habitual use of a high-pitched voice after puberty, hence why many refer to the disorder as resulting in a 'falsetto' voice.

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 ...
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 ...
A voice change or voice mutation, sometimes referred to as a voice break or voice crack, commonly refers to the deepening of the voice of men as they reach puberty.Before puberty both sexes have roughly similar vocal pitches, but during puberty the male voice typically deepens an octave, while the female voice usually deepens only by a few tones.
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.
The upper pitch range of the human voice is, on average, about half as high in males as in females. [3] Even after controlling for body height and volume, the male voice remains lower. Charles Darwin suggested that the human voice evolved through intersexual sexual selection, [4] via female mate choices.
Adult male voices are usually lower-pitched due to longer and thicker folds. The male's vocal folds are between 1.75 cm and 2.5 cm (approx 0.75" to 1.0") in length, [3] while females' vocal folds are between 1.25 cm and 1.75 cm (approx 0.5" to 0.75") in length. The vocal folds of children are much shorter than those of adult males and females.
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.
