Ear ringing from sudden loud noise or prolonged exposure to high levels of noise is the major cause of tinnitus today! The noise associated with this tinnitus sort are cricket and cicada sounds as well as a high pitched ringing in the ears. For more info goto

Enceladus up there above me has your answer. There will only be ‘amplifier’ solutions for your friend, be they by surgery or other aids that send “white noise” to drown out the ringing. Hearing loss cannot be reversed.

No. Basically, hearing loss is irreversible. There are cochlear implants, but those aren’t a reversal of hearing loss, just an aid to improve hearing. Tinnitus is actually common for many people. Most people get it, but extreme tinnitus is a constant problem and results in hearing loss. In those cases, the damage is generally not reversable. However, ringing in the ears goes away in most people if it isn’t serious.

There are many treatments that are effective for tinnitus resulting from a particular cause, but none are effective in every case. Conversely, tinnitus may resolve without any treatment. Effective treatments include:

Objective tinnitus:

Gamma knife radiosurgery (glomus jugulare)[18]
Shielding of cochlea by teflon implant[19]
Botulinum toxin (palatal tremor)[20]
Propranolol and clonazepam (arterial anatomic variation)[21]
Subjective tinnitus:

Drugs and nutrients
Benzodiazepines (xanax, ativan, klonopin)
Avoidance of caffeine, nicotine, salt[22][23]
Avoidance of or consumption of alcohol[24][23]
Zinc supplementation (where serum zinc deficiency is present)[25][26][27]
Acamprosate[28]
Etidronate or sodium fluoride (otosclerosis)[29]
Lignocaine or anticonvulsants (usually in patients responsive to white noise masking)[30]
Carbemazepine[31]
Melatonin (especially for those with sleep disturbance)[32]
Sertraline[33]
Vitamin combinations (lipo-flavonoid)[34]
Electrical stimulation
Transcranial magnetic stimulation or transcranial direct current stimulation[35][36]
Transcutaneous electrical nerve stimulation[37]
Direct stimulation of auditory cortex by implanted electrodes[38]
Surgery
Repair of perilymph fistula[39]
External sound
Low-pitched sound treatment has shown some positive, encouraging results.(UC, Irvine press release)
Tinnitus masking[40] (white noise)
Tinnitus retraining therapy[41][42]
Auditive stimulation therapy (music therapy)[43]
Compensation for lost frequencies by use of a hearing aid.[44]
Ultrasonic bone-conduction external acoustic stimulation[45][46]
Avoidance of outside noise (exogenous tinnitus)[47]
Psychological
Cognitive behavior therapy[48]
Although there are no specific cures for tinnitus, anything that brings the person out of the “fight or flight” stress response helps symptoms recede over a period of time. Calming body-based therapies, counseling and psychotherapy help restore well-being, which in turn allows tinnitus to settle. Chronic tinnitus can be quite stressful psychologically, as it distracts the affected individual from mental tasks and interferes with sleep, particularly when there is no external sound. Additional steps in reducing the impact of tinnitus on adverse health consequences include: a review of medications that may have tinnitus as a side effect; a physical exam to reveal possible underlying health conditions that may aggravate tinnitus; receiving adequate rest each day; and seeking a physician’s advice concerning a sleep aid to allow for a better sleep pattern.

am not sure but i think its a no
