Indeed, the noise floor of the fly-inspired microphone is about 17 decibels lower than what can be achieved using a pair of low-noise hearing aid microphones to create a directional hearing aid.
A few studies have examined directional hearing aid use with subjects with severe-to-profound SNHL.
Noise-source correlation is another factor that must be considered in directional hearing aid research.
The comparison with normative data, however, does not allow for a conclusion about the amount of benefit that is attributable to the directional hearing aid alone.
The exception to this pattern was for the service and cost subscale, for which the directional hearing aid condition was rated significantly higher than the omnidirectional condition, which in turn was rated higher than the old aid condition.

Directional hearing aids are designed to provide less amplification for sounds that are generally behind the listener in comparison to sounds arriving from in front of the listener.
Much of my recent research has been focused on examining the benefits and limitations of the directional hearing aids that I mentioned earlier in real world listening situations.
Since wind noise is predominantly low-frequency and typically a greater problem for directional hearing aids, a significant amount of the wind noise problem is alleviated by ReSound's Surround Sound Processor because low-frequency sound inputs are processed omnidirectionally.
The application areas of robust adaptive beamforming are also expanding, which include, for example, smart antennas in wireless communications, hand-held ultrasound imaging systems, and directional hearing aids.
There are also exciting emerging applications such as smart antennas for wireless communications, handheld ultrasound imaging systems, and directional hearing aids.
