• Amusia — A congenital or acquired neurological disorder (following a brain injury) characterized by the partial or total inability to recognize, hum, reproduce, or understand musical tones, rhythm, and melodies, despite biological hearing and general intellectual functions remaining perfectly intact; tone deafness. This structural phenomenon affects the cognitive processing of sound structures in the secondary auditory cortex.
• Amusia variant — An extremely rare medical and neurological term, sometimes used as a variant or graphical error for 'amusia' or as a niche synonym for the congenital or acquired inability to correctly perceive and process rhythmic structures and tone elements of speech or music. It represents an anomaly in the central auditory analyzer affecting the decoding of complex acoustic signals.
• Anacusis — Total, complete, and permanent loss of hearing in one or both ears, structurally caused by profound damage to the cochlea, the auditory nerve, or the cortical nerve centers in the temporal lobe. This clinical phenomenon differs from hypoacusis by the absolute absence of any functional residual hearing, depriving the patient of sound wave perception and requiring complex neuro-sensory rehabilitation strategies or cochlear implantation.
• Antehelix — A curved prominence of the external ear pinna, situated in front of and parallel to the helix, separated from it by the scaphoid fossa. This cartilaginous structure bifurcates in its upper part into two flexible crura that frame the triangular fossa, playing an essential role in capturing, reflecting, and guiding sound waves toward the external auditory canal.
• Amusia — A rare disorder of musical perception or a specific form of auditory agnosia characterized by a person's pathological inability to distinguish, recognize, or reproduce musical sounds, rhythms, or tones, despite the peripheral auditory function and the ability to understand spoken language remaining fully intact.
• Hearing impairment — A popular term for deafness or a temporary or partial loss of hearing; a pathological or accidental state where an individual's auditory capacity is structurally diminished due to loud noise, an inner ear condition, or aging.
• Auditory — Belonging to hearing, relating to hearing or its organs; destined for the perception of sounds. In a neurophysiological sense, the term describes all the structural and nerve channels responsible for transforming acoustic vibrations from the environment into bioelectric signals interpreted by the cerebral cortex.
• Auricular — Pertaining to the ear or the cardiac auricle; auditory. As a masculine noun, it designates the pinky finger (named so because its size fits the external auditory canal). In linguistics and historical theology, it describes a confession made directly into someone's ear (e.g., auricular confession).
• Hearing — One of the five fundamental senses of humans and vertebrate animals, through which sound waves from the environment are perceived; a complex physiological function performed by the auditory system (ear, acoustic nerve, and cortical centers in the brain), consisting of transforming mechanical vibrations into nerve impulses.
• To hear — To perceive sounds, noises, voices, or acoustic signals using the sense of hearing; to learn about something through the words of others, to find out, or to be informed; (reflexive) to emit sounds that can be perceived by those around.
• Hearing — The act of hearing and its result; the perception of sound waves by the auditory organ or the process through which information or a rumor comes to a person's knowledge; the sense of hearing viewed in its dynamic manifestation.
• Female listener — A female person who hears or listens to a speech, a broadcast, or an acoustic signal; as an adjective, it describes a living being or biological structure capable of perceiving sound vibrations from the surrounding environment.
• Hearer — A male person who hears, listens, or attends an acoustic event; as an adjective, it describes an organism, organ, or apparatus possessing the faculty to perceive acoustic waves from the environment.
