Phonophobia, also called ligyrophobia or sonophobia, is a fear of or aversion to loud sounds—a type of specific phobia. It can also mean a fear of voices, or a fear of one's own voice.^[1] It is a very rare phobia which is often the symptom of hyperacusis. Sonophobia can refer to the hypersensitivity of a patient to sound and can be part of the diagnosis of a migraine. Occasionally it is called acousticophobia.^[2]

The term phonophobia comes from Greek φωνή - phōnē, "sound"^[3] and φόβος - phobos, "fear".^[4]

Ligyrophobics may be fearful of devices that can suddenly emit loud sounds, such as computer speakers or fire alarms. When operating a home theater system, computer, television, CD player, etc., they may wish to have the volume turned down all the way before doing anything that would cause the speakers to emit sound, so that once the command to produce sound is given, the user can raise the volume of the speakers to a comfortable listening level. They may avoid parades and carnivals due to the loud instruments such as drums. As festive occasions are accompanied by music of over 120 decibels, many phobics develop agoraphobia. Other ligyrophobics also steer clear of any events in which fireworks are to be let off.

Another example is watching someone blow up a balloon beyond its normal capacity. This is often an unsettling, even disturbing thing for a person with ligyrophobia to observe, as he or she anticipates a loud sound when the balloon pops. When balloons pop, two types of reactions are heavy breathing and panic attacks. The sufferer becomes anxious to get away from the source of the loud sound.

It may also be related to, caused by, or confused with "hyperacusis", extreme sensitivity to loud sounds^{[citation needed]} Phonophobia also refers to an extreme form of misophonia.^[5]

Cardiophonophobia

Cardio Phonophobia is a branch of phonophobia and cardiophobia. People with cardiophonophobia are uncomfortable with hearing the sound of their own and/or other people's pulse and heartbeats. The reason for that is sometimes the fear of getting a heart attack, feeling the heart stop or hearing it skip beats. This could sometimes be caused by (or be the cause of) anxiety and panic attacks, but that is not always the case, as the person may just simply feel irritated by the sound of heartbeats and try to avoid hearing them, which is not necessarily a serious condition.
