The Signia/Siemens Primax is a water/dust resistant hearing aid touted to enable the user to hear as well in noise as the individual with normal hearing. I don't think this is hyperbole, and the general response of users is very, very positive. The primax is programmable for individuals with hearing loss from mild to severe. The operation of the device automatically changes with the environment, resulting in a responsive, automatic hearing aid. Smart phone apps designed by the manufacturer can be downloaded at no charge to use your iPhone as a remote control for the hearing aids.
This waterproof and dust proof hearing aid is designed for individuals with a mild to moderately severe hearing loss. Those with severe to profound hearing loss cannot benefit from this hearing aid. To swim with this hearing aid, the tube fit configuration is replaced with a screw on tone hook and custom snug ear mold to prevent water from ebbing into the hearing aid electronics from the ear canal. It works quite well!
Individuals with precipitous high frequency hearing loss will find terrific benefit from these newly released hearing aids. Clarity significantly improves. Unaided word discrimination scores of 60-70% often improve to the low 90s. Speech in Noise scores as measured with the Quick Sin test often improve by 10-13 dB. The improved streamer has more than doubled streaming hours. Tinnitus treatment is built in as a no-charge option, but often not needed, due to the amplification algorithm.
This is the best hearing aid I know about for individuals with a severe to profound hearing loss. It is water resistant, available at four levels of technology, and is often covered by state health insurance benefits.
Bluetooth (BT) technology continues to be available from nearly every manufacturer of hearing aids. The reason is clear: BT improves clarity on the telephone, on television, in groups, and at long distances, when it is programmed into the hearing aid. Several manufactures have discontinued the use of streamers. Each manufacturer has a different strategy; most manufacturers enjoy collaborating with Apple to make apps available to add very helpful features to the hearing aid.
