Can I hear the phone calling while watching TV?
It is possible to hear the phone calling while watching TV if the hearing aids are programmed with a streaming + microphone program. If the hearing aids are programmed with a streaming only program it is not possible to hear the phone calling while watching TV. If you have a Unite Phone Clip paired with your mobile it will automatically connect to the phone. Ask your Hearing Care Professional what program you have.
How do I take a phone call when I’m watching TV?
When the phone rings while you are watching TV, you can pick up the phone and the hearing aids will automatically change to PhoneNow if you have the phone magnet attached to your phone. You will hear an indication in the hearing aids that you are in PhoneNow. You will still have streamed signal in the other ear. When you hang up the phone the hearing aids will automatically go back to streamed sound, and you will hear an indication in the hearing aids that you are in streaming mode.
Can I hear my mobile phone ringing while watching TV?
Yes, it is possible to hear your mobile phone ringing if you have paired the phone to the Unite Phone Clip. The phone signal will be received in both ears.
Is there extended bandwidth with ReSound Alera?
Yes, the bandwidth extends to 7000 Hz.
Why is there no volume control? How can I change the volume?
For the Alera wireless 312, the volume can be controlled directly by the wearer with the optional Unite Remote Control. For all Alera models, environmentally dependent volume control settings can be configured in the Environmental Optimizer II in the Aventa3 software.
Why doesn't ReSound Alera have a LP receiver?
The LP receiver was introduced primarily to allow individuals with normal or near-normal hearing to use the Live TS tinnitus feature without circuit noise from the instrument masking the tinnitus sound generator signal. Potentially, this receiver could also alleviate noise complaints of those with mild hearing losses who complained of noise with the Live. Because of the new ReSound Range chip, the noise floor of the circuit has been reduced dramatically, eliminating the need for a receiver with lower output.
In Aventa, the dispenser has the option of shifting the crossover frequency (or blending point) higher or lower. Why and when would they want to do this?
In the Aventa software, the shifting of the blending point occurs through changes to the 'Directional Mix' setting. The Directional Mix setting is inversely related to the crossover frequency. A very low Directional Mix setting results in the highest blending point, and provides less directionality in the low and mid 'frequencies. Increasing the Directional Mix setting decreases the blending point, thereby providing more directionality in the low and mid frequencies. If the patient complains of difficulty understanding conversation in a noisy surrounding, the Directional Mix setting should be increased. If the patient complains that the hearing instrument is too noisy in quiet situations or desires more listening comfort, then the Directional Mix setting should be decreased. Note that because the mixing point is calculated automatically, the settings should only be changed when the patient's needs can be clearly and accurately assessed.
When you change the Directional Mix setting, is there any change in the low frequency intensity?
No. Changing the directional mix will cause the hearing instrument to have a larger or smaller omnidirectional frequency range, but there is no intensity or gain change.
How is band-split directionality calculated?
Band-split directionality is calculated in all directionality modes according to the average of the hearing thresholds at 250 and 500 Hz for each ear. Hearing instrument style is also taken into account.
For patients who do not use the memory button appropriately, what is the best directional option, especially if Natural Directionality II is not available?
SoftSwitching is the best directional option for patients who do not use the memory button appropriately, if Natural Directionality II is not available.
What is the significance of AutoScope Adaptive Directionality? How is it different from MultiScope Adaptive Directionality?
AutoScope Adaptive Directionality improves upon MultiScope directionality by making automatic adjustments to the beamwidth through environmental steering. AutoScope automatically adjusts the directional beamwidth based on the relative levels of the inputs to the front and rear microphones. As the signal to the front becomes more intense, the beamwidth narrows. As the signal to the front becomes less intense, the beamwidth widens, allowing more audibility for surrounding sounds. AutoScope Adaptive Directionality creates an effect of zooming in on the speakers if they are directly in front of the listener, and zooming out when the listener is surrounded by many speakers.
Why is there a NoiseTracker II per environment setting? Doesn’t NoiseTracker II adapt automatically?
NoiseTracker II does automatically change the amount of noise reduction applied based on an estimate of the signal-to-noise ratio. However, it is limited by the Aventa setting to mild, moderate, etc. This means that the maximum amount of noise reduction applied may not be what is most beneficial for the user in a given situation. For example, a smaller degree of noise reduction is often preferred for quiet situations, and a more aggressive setting for a noisy situation, such as riding in a car. This is why we have different NoiseTracker settings in different environment programs. The Environmental Optimizer II automatically sets the maximum amount of noise reduction possible that is most appropriate for the specific environment that is identified by the environmental classifier - without the user having to identify the environment and manually change programs for the optimum setting.
Why are there 7 environments to adjust NoiseTracker II in? Noise is not in all environments.
There is always input sound to the hearing instrument, even in environments with no noise. In environments with no noise, the inputs are low level, and the compression system amplifies low level sounds the most. Thus the hearing instrument can sound noisy to the user both in quiet and noisy situations. NoiseTracker II is of benefit in all types of sound environments, both with and without noise. It reduces amplification of both unwanted noise, as well as amplification when there is no sound of interest, making using a hearing instrument a more comfortable and less tiring experience.
When should I change the slider for NoiseTracker II per environment - based on what info?
Changes in NoiseTracker II settings can be motivated by complaints regarding clarity or noisiness, particularly when they are related to specific types of environments. For example, if the patient reports that it is a great effort to follow the conversation at a noisy restaurant and that other voices seem muffled, it might be helpful to increase the NoiseTracker II one step in the speech in noise environments. A patient with a severe hearing loss might complain that they aren't hearing as much as they would like to or that they feel disconnected. For them it might be helpful to decrease the degree of NoiseTracker II in noise and speech in noise environments.
Will DFS Ultra/Whistle Control change its setting automatically based on the calibration or is that the dispenser's choice to make?
The default level is 'mild' but the dispenser may choose to change the setting.
