The Mind330 is a 10 channel product, with a feature-set controlled by the Widex Dual ISP chip. One of the talking points of the list of new features introduced by the Dual ISP was the Audibility Extender.
The Audibility Extender is intended primarily for children and adults with steeply sloping or severe to profound hearing loss. In a steeply sloping hearing loss, the vast majority of the hearing loss lies in the very high frequencies. Since many speech sounds are located in the high frequency region, discrimination can be significantly impaired without access to high frequency input. Sounds such as /s/, /f/, /t/, /z/ may all be missed, and a great deal of guesswork needs to be done by the hearing impaired person. The Audibility Extender aims to increase the audible range of the hearing aid wearer. This is done by moving the inaudible high-frequency speech sounds, and environmental sounds like birdsong, a doorbell, music, etc. to a frequency region where they are audible. One section of frequencies is moved to a lower range of frequencies without compressing or distorting the signal.
For a mid range product, the Mind330 still offers many of the features seen in the top of the range Mind440. In this way, it is certainly much more highly featured than the next level down, the Mind220.
SmartSpeak was introduced with the Mind products – quite an unusual feature for hearing aids – it provides the wearer with information about their hearing aid in the form of a recorded voice – so instead of hearing beeps or tones indicating when, for example, programme changes have taken place, a recorded voice will ‘tell’ the wearer that they are now in ‘Programme 2’. This is now a standard feature in the ranges introduced after Mind.
The Mind330 products are available in behind-the-ear or custom-made ITE styles. The in-the-ear options also include the IIC design – invisible-in-canal.
