Hyperacusis / phonophobia has been treated and seriously studied by Michael Zazzio at Audio Laser-Kliniken. Michael Zazzio has been doing clinical research on the treatment of hyperacusis. The results display that the condition will almost always improve. In his hyperacusis study there were 69 (83.13%) out of 83 treated ears that were improved on pain thresholds by 10 dB or more. All ears improved. The average improvement per ear was 15.37 dB. Among the 444 observations the average improvement per observation was 15.26 dB. 417 (93.92%) of the observations were improved. The positive effects of the treatment are often long lasting. Long term follow up after 4-6 months shows almost 10 dB greater improvement than immediately after finished therapy. The average long term follow up improvement 4-6 months after finished therapy per ear was 21.82 dB. All ears improved. Among the 80 long term follow up observations in the study the average improvement per observation was 23.19 dB. 79 (98.75%) of the 80 long term followed up observations were improved. According to this, long term effects are much greater than the immediate effects obtained.

Patients who were treated for 20 sessions received much better treatment effects than those who were treated for only 10-12 sessions. 444 hyperacusis observations have been made at the Audio Laser-Kliniken during the past five years and the treatment effects are consistent.

Many of those patients who are suffering both from hyperacusis and tinnitus often claim that their oversensitivity to sound is a greater problem and more difficult to handle than the tinnitus. Also diplacusis (twanged tones) and distortion (unclear hearing), symptoms which create tremendous problems for musicians, can be treated with positive results.

Before this clinical study was reported there had never been any functioning treatment method for hyperacusis, but now this method is systematically used and the treatment results are sometimes described as “incredible” by ENT doctors. But the results are not viewed as incredible for those who have verified the positive effects that most patients get.



There are more 500 reasons why tinnitus may develop. In rare cases the tinnitus can reach over 30 dB above the hearing threshold. At Audio Laser-Kliniken several patients have had a tinnitus level between 35 and 40 dB above the hearing threshold.

Mostly the tinnitus symptoms can be related to the inner ear, but there are of course sometimes other reasons for the symptoms.

Seven LASER therapy research studies show that most patients with tinnitus improve from LASER therapy. In the best tinnitus studies the condition is improved for 81-95% of the patients.

According to a study at the Karolinska Institutet, Sweden, conducted by Tullberg och Engberg, 56% of all untreated tinnius patients with TMD had a more intense tinnitus after two years of waiting. Only 12% of them had a lessened tinnitus from doing nothing. So, the statement that tinnitus symptoms go away all by themselves is true, but quite uncommon. I presume it is the same with hyperacusis, impaired hearing, Ménière's disease and the other hearing and balance disorders. The hearing capacity continuously gets worse as time goes by, and logically that brings along a smaller chance to recover from a treatment made in the future instead of now.

Michael Zazzio has studied 23 tinnitus patients who were also suffering from hyperacusis. 22 (96%) of the patients had less tinnitus after LASER therapy, and 6 (26.1%) got rid of their tinnitus problems.



Chronic hearing impairment can be treated, sometimes with very good results. The best average improvement at Audio Laser-Kliniken for a patient suffering from a chronic hearing impairment is 42.73 dB. Hearing improvements in single frequencies have been measured up to 60 dB. The improvements are even larger than that for patients suffering from sudden deafness.



When sudden deafness / sensorineural hearing loss (SSNHL) occurs the best average hearing improvement after LASER therapy has been measured to 49 dB. The largest single frequency improvement is 80 dB.



Tympanic membrane damages can be treated successfully. The same goes for bleedings. An example of the positive effects on a perforated tympanic membrane is a patient who had a perforated tympanic membrane for 16 years. The membrane didn't heal at all during that period of time. The patient was treated at the Audio Laser-Kliniken in the spring of 2007. After ten treatments including LASER therapy the tympanic membrane was healed and the patients tinnitus had gone down from 17.5 dB above the hearing threshold to 7.5 dB above the hearing threshold.



The anti-inflammatory effects of the LASER light positively affects such conditions in the ear. Chronic inflammatory processes mostly get better from the treatment.



For single frequencies the hearing improvement of patients with Ménière has been measured up to 55 dB and an average hearing improvement for the Ménière patient receiving the best result has reached 30.45 dB. This patient group also very often gets other positive effects from the treatment such as improvements in tinnitus, balance and vertigo.



Balance disorders such as vertigo are treated with positive results among most patients treated with LASER therapy.


There are more hearing and balance related symptoms, conditions, dysfunctions and diseases that can be successfully treated with LASER. This list is very brief and contains only the most frequent disorders treated at Audio Laser-Kliniken.
