Although the Widex DREAM330 range is the second level of technology, it still shares a large number of features seen in the top of the range 440 series, not seen further down the pricing options. This should make it a fairly attractive option compared to the next level down – the Dream220.
Some of these features seen in the Dream330 but not in the Dream220 include the Digital Pinna, Personal Audibility Extender and TruSound softener features.
As there are a wide range of receiver-in-the-ear and behind-the-ear products in the range, the Digital Pinna feature is worth looking at in more detail: In a nutshell, this can help users of products fitted behind the ear to distinguish between sounds (especially speech) coming from either the front or back.
The human ear has some natural directional characteristics, mainly due to the shape of the outer ear or pinna, which help us to decide if a sound is coming from in front or behind, especially for frequencies around 2-8 kHz. One example of these natural directional characteristics is called the pinna shadow effect. Sounds coming from the front reach the ear canal almost directly, whereas sounds coming from behind are partially blocked by the outer ear and decrease in volume before they reach the ear canal. At some frequencies this attenuation can be as much as 3-4 decibel relative to sounds coming from the front. This difference in volume is important for the listener to know whether a sound source is in front or behind them.
Behind-the-ear hearing aids, where the microphones are usually located behind the pinna, will not preserve this pinna shadow effect, and the hearing aid user therefore loses some of the ability to distinguish front and back. The Widex Digital Pinna feature uses digital processing to restore this natural function.
Full range of styles available, including two different receiver-in-ear designs.
