Indications for Use
The Evok series is designed for use in sound therapy for tinnitus retraining therapy, masking, or other recognized forms of tinnitus treatment. Sound therapy should be used in concert with counseling from a physician, an audiologist or other qualified tinnitus specialists. The target population for this product is primarily the adult population 18 years of age and older. The target group for this product includes individuals reporting tinnitus who can also benefit from an air conduction hearing aid. NOTE: The Evok 900 series Tinnitus Masker Devices are targeted primarily to the adult population over 18 years old. Our User Guide does state this but it also has a statement that reads; "a child with a hearing loss should be directed to an Audiologist for evaluation and rehabilitation". This is not meant to be a contradiction considering the user guide is generic in the general information supplied to the end user. As part of a Tinnitus Management Program, we suggest the following recommendations applicable to clinical settings for all the devices listed above; The Tinnitus Management treatment should include evaluation and recommendations done by a qualified audiologist, otorhinolaryngologists or other licensed hearing healthcare professional. Since tinnitus can be associated with a number of auditory conditions, the audiologic evaluation can yield extensive information regarding the possible cause for the tinnitus and options for a successful Tinnitus Management treatment.
Device Story
Evok 900 series combines air conduction hearing aid and tinnitus masker in single instrument; intended for patients with tinnitus and hearing loss. Device generates broad-band noise for tinnitus masking therapy; provides amplification for hearing loss. Programmable volume controls allow independent adjustment of noise level and hearing aid gain. Dispenser, audiologist, or user adjusts noise/amplification mix. Used in clinical settings under guidance of qualified hearing healthcare professionals. Benefits include perceived tinnitus reduction and improved hearing. Device does not exceed OSHA 29 CFR 1910.95 amplification limits.
Clinical Evidence
Bench testing only. Evidence consists of electroacoustic performance data demonstrating similarity to predicate devices. No clinical trials were conducted; safety is established by the long-term market history of Class I hearing aid technology.
Technological Characteristics
Custom and standard air conduction hearing aids (BTE, OTE, RIC, CIC). Features hybrid circuit for programmable acoustical properties and broad-band noise generation. Materials and construction consistent with Class I hearing aids. No specific ASTM standards cited. Connectivity is limited to programmable internal circuits.
Indications for Use
Indicated for adults 18+ years old with tinnitus and hearing loss who require sound therapy (masking/retraining) and air conduction amplification. Contraindicated for children without professional audiologic evaluation and rehabilitation.
Regulatory Classification
Identification
A tinnitus masker is an electronic device intended to generate noise of sufficient intensity and bandwidth to mask ringing in the ears or internal head noises. Because the device is able to mask internal noises, it is also used as an aid in hearing external noises and speech.
