What is omni directional hearing aid?
An omnidirectional microphone is a microphone that picks ups sounds from all sides and directions, whether the sound is coming from the front, back or side of the wearer. This type of microphone is the technology traditionally used in hearing aids.
What is digital pinna?
Simulates the natural pinna effect to improve hearing aid users’ front/back localisation. The ear has some natural directional characteristics, mainly due to the presence and shape of the pinna (outer ear).
How do you adjust a Widex hearing aid?
Push the lever, or upper part of the control, upwards to gradually raise the volume. Push the lever, or lower part of the volume control, downwards to gradually lower the volume. Each time you operate the volume control, you will hear a beep – unless you have chosen to deactivate tones.

Can’t tell what direction sound is coming from?
The inability to distinguish spatial cues is known as spatial hearing loss. For example, if a person suffers from spatial loss of hearing, they would likely be unable to tell where a sound came from. They would also have a difficult time picking one person’s voice out of a crowd.
How do you test for directional hearing?
To measure directional performance, you can compare the response of the hearing aid when the signal source is in front of the patient (eg, the “forward response”) with the response of the hearing aid when the source is behind the patient (eg, the “reverse response”).
What is pinna effect?
The pinna is the flap of skin surrounding our ears. Reflected sound off the pinna combines with the direct sound into the ear to create high frequency comb-filtering effects (typically above 6kHz). These effects change as a function of angle of arrival, so that each angle of arrival has a unique sound quality.
What is head shadow effect?
The sensation of sound comes from our ability to distinguish the source of the sound based on the variation in the volume of sound perceived between both our ears. This phenomenon is known as the Head Shadow Effect. Lower frequency sounds tend to have longer wavelengths and range up to 1000Hz.
Why is my hearing aid volume so low?
If your hearing aids are working but the sound seems to be muffled or too soft, there is likely a buildup of wax on the microphone or earmold. Try thoroughly cleaning your hearing aid.
