Hyperacusis

Hyperacusis is a disorder often associated with tinnitus or sudden hearing loss. It refers to a sound sensitivity that exists independently of hearing ability. This phenomenon leads those affected to feel as though they are hearing more and better than usual. Sounds or music at normal volume levels are perceived as uncomfortably loud and even distressing. In extreme cases, even the noise of an air conditioner or one's own voice can be experienced as unbearable. Hyperacusis is generally a temporary condition and can be effectively treated through desensitization to sounds using psychoacoustic stimuli, such as Auditory Stimulation Therapy (AST®).

Auditory Processing and Perception Disorder (APD)       

APD refers to a disorder in the processing of auditory information in one or more sub-processes of cognitive auditory processing. Stress, traumatic or emotionally overwhelming experiences, or other illnesses such as depression can trigger this condition. Despite good hearing ability, speech comprehension and concentration are often significantly impaired. Through auditory processing training, these processing functions can be repaired, and speech understanding and concentration can be optimized.

Hearing Desensitization

Hearing desensitization refers to a disorder in the processing of auditory information in one or more sub-processes of cognitive auditory processing. It is caused by hearing loss that has persisted for more than three months. Hearing desensitization is characterized by impaired speech comprehension and concentration, even with the use of hearing aids. Noisy and loud environments are difficult to tolerate, and the source of sounds may be poorly recognized or not recognized at all. Through auditory processing training, these processing functions can be repaired, and speech comprehension and concentration can be optimized.

Phonophobia

In contrast to hyperacusis, phonophobia is not a general disorder of sound sensitivity, but rather refers to specific sound events where the experience of the noise is associated with certain negative experiences. For example, individuals who developed tinnitus after attending a concert may develop aversions or even fears of such events and avoid them. In these cases, a behavioral therapeutic approach (Psychological Immunization Training - PIT®) is useful, which aims to gradually habituate the individual to the situation instead of avoiding it, helping to counteract the fears.
