Brief summary

Tinnitus can be a possible complication of noise-induced hearing loss (NIHL) which is usually observed at frequencies equal to or higher than 3000Hz and one octave band higher than the frequency affected due to NIHL. A method which has been proposed for the treatment of tinnitus is low-level laser therapy (LLLT). This study was designed to evaluate the effect of LLLT on tinnitus accompanied by NIHL.

Interventions

Low-level laser therapy Laser properties: 5mv laser with a wavelength of 650nm Duration & frequency:20 minutes each session,every other day Overal duration: Laser therapy for 20 sessions (40 days)
