The main purpose of this study is to investigate whether cognitive behaviour therapy (CBT) can be useful for people suffering from Hyperacusis.
Also, the investigators are interested in investigating this group of patients on psychiatric and somatic comorbidity, personality traits, and startle response to sounds.
The investigators will also study the audiological measures commonly used in Sweden to measure hyperacusis, and investigate their validity.
The investigators hypothesize that CBT might be helpful for patients suffering from Hyperacusis.
Hyperacusis, defined as unusual intolerance to ordinary environmental sounds, is a common problem for which there are no controlled trials on psychological treatment. Given the avoidance strategies present in hyperacusis, and similarities with problems such as tinnitus and chronic pain, cognitive behaviour therapy (CBT) is hypothesized to be helpful for patients with hyperacusis. In this randomized controlled study of 60 patients with hyperacusis, CBT was compared with a waiting list control group using the Loudness Discomfort Level test (LDL), the Hyperacusis Questionnaire, the Hospital Anxiety and Depression Scales, the Quality of Life Inventory and an adapted version of the Tampa Scale of Kinesiophobia. There were significant between-group effects in favour of the CBT group on all measures except for the HADS anxiety scale. Between-group effect sizes were moderate to high, with Cohen's d = 0.67 and 0.69 per ear, respectively, for the primary measure LDL, and ranging from d = 0.32 to 1.36 for the secondary measures. The differences between groups ceased to exist when the waiting list group was treated later with CBT, and the treatment results were largely maintained after 12 months. In conclusion, CBT is a promising treatment for hyperacusis, although more research is necessary.

| Quality of Life Inventory (QOLI) | Inventory measuring how patients' percieve the importance of and their satisfaction with many variables that concludes life quality, for instance economy, physical health and family life. | Evaluation for participance (day one), before treatment for waiting list patients (up to 6 months), direct after treatment, 12 mts after treatment |
| Khalfa Hyperacusis Questionnaire | A questionnaire to quantify and evaluate various hyperacusis symptoms, screening several aspects of auditory symptomatology. | Evaluation for participance (day one), before treatment for waiting list patients (up to 6 months), direct after treatment, 12 mts after treatment |
| Loudness discomfort threshold | Audiological measure where the patient is exposed to sounds, gradually of higher volume. The patient is instructed to indicate when the sound level is uncomfortably loud, and that terminates the exposure. The test is performed by an audiologist using a calibrated audiometer. | Time Frame: (FDAAA) Evaluation for participance (day one), before treatment for waiting list patients (up to 6 months), direct after treatment, 12 mts after treatment |

The Swedish version, 5.0.0. was used. | At evaluation for participance (day one) |
